Run UBI on NAND flash (3 replies)

Stephen — Mon, 29 Mar 2010 18:16:59 -0600

Hello,

Is it possible to run UBI on the entire NAND flash (mtd device), then have the bootloader, kernel, and root filesystem running on top of UBI?

Or even run UBI on a partition of the NAND flash?

Thanks.

oprofile on Snapper 9260 (no replies)

IGW — Tue, 09 Mar 2010 18:18:58 -0700

Hi all,

I have looked (a bit) into running oprofile (profiling package) on the Snapper 9260. It is not going all that smoothly for me. I have found the right (I think) menuconfig options to enable to get the oprofile driver in the kernel. The problem is making sure I have got the right libraries and letting the oprofile configure script know this.

Are there any instructions for getting oprofile (and any required libs) on the Snapper 9260? (Under the 2.6.29 kernel in my case.)

Would this be a useful package to have available in the Bluewater repository for ipkg-cl to access?

Thanks,
Ian

Both post installation script requires: update-alternatives command which I couldn't find it anywhere in the system and [www.bluewatersys.com].

DHCP (4 replies)

mylesdw — Wed, 17 Feb 2010 14:37:30 -0700

Can you point me in the direction of some instructions for getting an IP by DHCP during a 'normal' BOOTD of a Snapper 9260. I just want the IP without all the other dhcp_boot stuff.

I tried adding ip=any to the boot_args but this does not quite work...

Thanks

OSS emulation "asoc: machine hw_params failed" (no replies)

nathanaelg — Thu, 10 Dec 2009 13:00:56 -0700

I am trying to get the VoIP framework sipXtapi running on a snapper 9260 but it requires OSS audio. I recompiled the 2.6.29 kernel after adding in OSS emulation using make menuconfig and then created /dev/dsp but when I try and play audio using OSS (e.g. using madplay) I get:

error: frame 0: lost synchronization
output: ioctl(SNDCTL_DSP_SPEED): Device or resource busy

and dmesg shows:
asoc: machine hw_params failed

Any ideas as to what is causing this and how to fix it?

Upgrade alsa in kernel (no replies)

I am wanting to upgrade Alsa to 1.0.21 (from 1.0.18a in your latest kernel) to be able to use more sample rates for the tlv320aic23. Is this possible using the alsa-driver from [www.alsa-project.org] How would I go about doing this?

Audio not playing correctly at sampling rates other than 44.1kHz (no replies)

nathanaelg — Wed, 02 Dec 2009 21:19:05 -0700

I have been unable to get aplay to play audio correctly at sampling rates other than 44.1kHz. For some reason at 8kHz, 32kHz, 48kHz the audio is played faster than it should be. Is this likely to be a limitation of the driver in the kernel or something else to do with my setup?

When installing ppp, libpcap0.9 also gave the same error. Why is this likely to be?

Tweaking time slice (2 replies)

IGW — Tue, 27 Oct 2009 14:47:42 -0600

Hi all,

It seems that the stock kernel on the Snapper 9260 has a basic time slice of 100 ms:
#define DEF_TIMESLICE (100 * HZ / 1000)

Will I get myself into a lot of pain if I reduce this to 10 ms?

I have some external buffering in some hardware that only provides about 100 ms of buffering. I guess I could run it as an interrupt, but I am keen to know if I can get an adequate result by tweaking the timeslice to 10 ms at least for the current development phase.

Thanks,
Ian

bluetooth pairing problem (24 replies)

Henry — Thu, 22 Oct 2009 16:28:04 -0600

Hi,

All the configuration of Bluetooth on snapper has been set properly, however, pairing is always failed when any other bluetooth devices request a pin from snapper. The snapper can't response to any request at all.

i think the problem can be seen from "/etc/bluetooth/main.conf" and D-bus as shown below, but I don't know how to fix it

root@snapper:$ hcid -n
hcid[702]: Bluetooth HCI daemon
hcid[702]: Parsing /etc/bluetooth/main.conf failed: No such file or directory
hcid[702]: Unable to get on D-Bus

And this is my /etc/bluetooth/hcid.conf file, which I can't see any problem

root@snapper:~$ cat /etc/bluetooth/hcid.conf
#
# HCI daemon configuration file.
#

# HCId options
options {
# Automatically initialize new devices
autoinit yes;

# Security Manager mode
# none - Security manager disabled
# auto - Use local PIN for incoming connections
# user - Always ask user for a PIN
#
security user;

# Pairing mode
# none - Pairing disabled
# multi - Allow pairing with already paired devices
# once - Pair once and deny successive attempts
pairing multi;

# Default PIN code for incoming connections
passkey "1234";
}

# Default settings for HCI devices
device {
# Local device name
# %d - device id
# %h - host name
name "%h (%d)";

# Local device class
class 0x120112;

# Default packet type
#pkt_type DH1,DM1,HV1;

# Inquiry and Page scan
iscan enable;
pscan enable;

# Default link mode
# none - no specific policy
# accept - always accept incoming connections
# master - become master on incoming connections,
# deny role switch on outgoing connections
lm accept;

# Default link policy
# none - no specific policy
# rswitch - allow role switch
# hold - allow hold mode
# sniff - allow sniff mode
# park - allow park mode
lp rswitch,hold,sniff,park;

}

And this is the /etc/init.d/bluetooth file, which I think may be of some problem

root@snapper:~$ cat /etc/init.d/bluetooth
#!/bin/sh
#
# Start/stop the Bluetooth daemons
#

set -e

PATH=/sbin:/bin:/usr/sbin:/usr/bin
NAME=bluetooth

HID2HCI_ENABLE=false

DAEMON_CONFIG="/etc/bluetooth/hcid.conf"

[ -e /etc/default/bluetooth ] && . /etc/default/bluetooth

case "$1" in

The option "USB Serial Converter support" has and I tried to include it by type "Y", however, the same message appears

"This feature depends on another which has been configured as
module. As a result, this feature will be configured as a module"

I am putting this question on forum soon

Thanks

Missing /proc/snapper and /proc/gpio (6 replies)

IGW — Thu, 11 Feb 2010 17:41:28 -0700

I assume I have done something wrong or I have missed some vital step that Linux gurus would all know by heart.

I was trying to disable the Ethernet for a 9260 using the instructions in the FAQ.

echo eth_power disable > /proc/snapper/power_domain

just gives:
-sh: cannot create /proc/snapper/power_domain: nonexistent directory

There is no ..../snapper or .../gpio in /proc.

I assume I have not updated the root file systems in the correct manner.

Are there any instructions for using the root file system builder? I gave it a go by running the python scripts and then trying to figure out the options. No success. Some brief guidance would be appreciated.

Thanks,
Ian

update root file system and kernel (no replies)

henry — Sun, 11 Oct 2009 09:17:51 -0600

I've typed the following to check which mtd partition is allocated for the root filesystem, would you please indicate the right one out of the three

root@snapper:~$ cat /proc/mtd
dev: size erasesize name
mtd0: 00200000 00020000 "Internal_Kernel"
mtd1: 3fe00000 00020000 "Internal_Data"
mtd2: 40000000 00020000 "Internal_Whole"
root@snapper:~$

I am going to use the following commands to replace the old root filesystem with the new one, please suggest if the steps are correct

mtdtool --eraseall /dev/mtdX
mount -t yaffs /dev/mtdblockX /mnt
cp -a /path/to/root/filesystem /mnt
umount /mnt

Due to the unsuccessful NFS server setting, I am going to use a USB stick to exchange the data. In terms of the "/path/to/root/filesystem", I wanna direct it to the usb stick (say I mount the usb to /mnt/usb) which has the downloaded root filesystem "root.tar.gz". My question is should I use the root.tar.gz file, or un-tar it and then use it?

Furthermore, would you please give some detailed instruction on how to update a linux kernel on Snapper CL15 using the usb stick as the method of transferring data. I've read the FAQs but they are only for 9260.

Thanks

the 2nd serial port and bluetooth module (no replies)

Henry — Thu, 08 Oct 2009 06:22:32 -0600

On page 34 of Rig 200 Software Guide, it says the 2nd serial port is shared with bluetooth. Therefore, I can't use the serial port and bluetooth at the same time.

However, what I am really wanna to achieve is collecting data from serial port 2 (J52 connector) and this data will be fed to the bluetooth for transmission at the same time. Meanwhile, I need keep the serial port 1 as the console with the host computer.

Would anybody give some solutions?

Power management under Linux (2 replies)

IGW — Thu, 08 Oct 2009 18:55:18 -0600

Hi all,

Does anyone have any good references to managing power under Linux? I am using the 2.6.29 kernel on a Snapper 9260?

I am contemplating whether we can sensibly boot Linux and then shut down into a low power mode to monitor a switch and then, when pressed do real work. All easy enough and I know I can shut down a lot of peripherals like the Ethernet, USB etc. But I am wondering how easy it is to manage power (from user space preferably). I really only have two states I am interested in (on and standby) and standby does not need to be very low (something less than 0.5W would be good).

All this would be easy running without an OS, but I am wondering if this is also easy within Linux. I am sure it can be done, but I am wondering what is the generally considered "best" way.

It is not worth me spending a lot of time on just now, so that is why I am throwing the question out there looking for any brief comments. I have done some looking around on the web.

Many thanks for any pointers and suggestions,
Ian

Hi All,

I build on a PC linux a new kernel and I need test it on my snapper module using one of the various boot methods available in the U-Boot environment.

Could you please tell me how set up the my PC linux server side to do that (which network services I have to setup ? DHCP, TFTP, NFS ?)

Thank you

Need advices on GPIO and external interrupts (3 replies)

tuanpa — Thu, 01 Oct 2009 13:35:09 -0600

Hi,

I have 2 questions, and need your advices to know how to start. My applications is based on Linux (Code Sourcery 2007q3 release), the module is Snapper9260.

1. I have an external board that have the status pin that show the ON or OFF status. The pin is high level (3.3V ), the board is ON. If the pin is low level (0V), the board is OFF.
My program needs to read the status of this pin before do some works.

2. I have another board that installed on the door. When the door opens, the board set a pin to high level (3.3V). Otherwise, set that pin to low level (0V).
I needs to know when the door opened, closed.

Thank you,

spidev crash on Snapper 9260 (2 replies)

pas — Thu, 24 Sep 2009 07:01:51 -0600

I have added the spidev module to my 2.6.29 kernel and it seems to initialize correctly but I get a crash when I try to use the device.

I added the following to board_snapper9260.c:

static struct spi_board_info spi0_board_info[] __initdata = {
        {
                .modalias       = "spidev",
                .max_speed_hz   = 15 * 1000 * 1000,
                .chip_select    = 0,
                .bus_num        = 1,
        }
};

static void __init sn9260_board_init(void)
{
    at91_add_device_spi(spi0_board_info,ARRAY_SIZE(spi0_board_info));
    .........
}

On boot dmesg shows:

atmel_spi atmel_spi.1: Atmel SPI Controller at 0xfffcc000 (irq 13)
atmel_spi atmel_spi.1: registered master spi1
spi spi1.0: setup: 12861888 Hz bpw 8 mode 0x0 -> csr0 00000702
atmel_spi atmel_spi.1: registered child spi1.0

....and after using mdev -s I have a /dev/spidev1.0 device.

If I then try and use one of the spidev test tools (spidev_test or spidev_fdx) I get the following crash:

Did I miss something? is there something else I need to set up before using this module?

Any help would be appreciated.

Updating kernel and File System (18 replies)

IGW — Sun, 21 Mar 2010 18:57:14 -0600

Hi all,

I have been trying to update the file system and kernel on a Snapper 9260.

I am booting from an uImage I download from an NFS share and the file system is on the (same) NFS share.

To update/refresh the file system in flash I mounted mtdblock4 and copied everything from the NFS file system to the mount (I created the /proc folder but I did not copy the stuff within - doing so hangs the Snapper):
mount /dev/mtdblock4 /mnt
then "cp -a" everything apart from the /proc folder then manually create the /proc folder.

This seemed to go OK.

To update the kernel I followed the instructions in the FAQ and this also seemed to go OK.

However, when I try to boot from flash it is unsuccessful. Following is the terminal dump of the boot process.

I am sure I have done something wrong but I don't know what.

The yaffs boot commands (uboot) are (or should be) unchanged from the factory settings.

Thanks,
Ian

tcsetattr failing (8 replies)

rszemeti — Thu, 17 Sep 2009 04:02:57 -0600

Hi,

I'm busy trying to get some code to run on a 9260 and failing....

In a nutshell:

I set the ser port speed ...

if( cfsetispeed(&options, Baud) <0 || cfsetospeed(&options, Baud) <0){ ... }else{ ...}

check it with cfgetospeed() on the file descriptor and its fine ...

then I set some flags,

options.c_oflag &= ~OPOST;
options.c_oflag &= ~ONLCR;

/* snip more setting of options flags like VMIN etc etc */

tcflush(sPort, TCIFLUSH);

if (tcsetattr(sPort, TCSANOW, &options) != 0) {
return 0;
}

check the port speed again and its a mess ( monitoring the serial port confirm it, should be 9600, but looking on the 'scope it looks more like 115200)

The code compiles and runs fine on i686, but when compiled for arm with the CodeSourcery compiler, its borked.

Any clues as to where to start looking

ipkg updates? (7 replies)

rszemeti — Thu, 10 Sep 2009 16:20:22 -0600

So, my QSK popped through the post and very neat it looks too.

First step was to try and grab a few packages, however, the as-shipped ipkg conf:

src/gz base [server.bluewatersys.com]
src/gz all [server.bluewatersys.com]
src/gz snapper [server.bluewatersys.com]

does't seem to work (redirects to an https server that doesnt have the packages)... I can only assume in between shipping the unit and it arriving, the web server config got changed,

any clues as to where it now lives?

Access to U-Boot environment vars from Linux (13 replies)

pas — Thu, 01 Oct 2009 13:26:04 -0600

Has anyone successfully used the fw_setenv tool (from u-boot/tools/env) to modify
or set new U-Boot environment vars from linux? Also is there a backup image of the Parameters
flash partition for the Snapper available on-line?

I have built the U-Boot fw_* tools and fw_printenv correctly shows my U-Boot environment,
unfortunately when I used fw_setenv it erased my U-Boot environment and I had not made
a backup.

Regards,

Pete

Serialport questions (4 replies)

tuanpa — Fri, 04 Sep 2009 16:35:55 -0600

Hi,

I write a program to test serial port based on the code serial_test from [www.bluewatersys.com] with a little changed.

It works with /dev/ttyS2 but doesn't work with /dev/ttyS0 and /dev/ttyS1. Can I use the ttyS0 and ttyS1 without handshake?

If the ISI will not be used, can I enable the UART3 and UART5 of the 9260 for more serial ports. Is it required to modify and recompile the linux image?

Thank you,

Hello,

Are you able to provide steps to build u-boot from source downloaded from your website? Just like the one shown for building linux kernel.

Thanks

SerialPort and Java on Snapper9260 (1 reply)

tuanpa — Thu, 20 Aug 2009 15:20:16 -0600

Hi,

I'm trying to use SerialPort and Java on the snapper9260. But I couldn't manage to build the librxtxSerial.so (source from [rxtx.qbang.org] ).

Is there anyone ports the source for Snapper9260?

Thanks,
