[mini2440] barebox nand flash erase and jffs2 cleanmarkers

Hello all,

I am working with ptxdist-2013.09 on a mini2440 board.

When erasing a nand partition from barebox, is it possible to tell it to write the jffs2 cleanmarkers to the OOB area? I see there is support for this in barebox/drivers/nand/nand_util.c but can't find how/where this is used.

Thank you,

enable hostap

Dear Experts,

I tried to setup an access point on a development board that runs with OSELAS. I enabled the hostap under
wpa_supplicant and tried to follow the steps for raspberry pi that I found on the internet.

http://xmodulo.com/raspberry-pi-wifi-access-point.html

for some reason, i could not find udhcpd.conf in /etc and also hostapd.conf. I believe the way of setting up
wifi access point using OSELAS is different from raspberry pi.

Anybody could help me how to setup the wifi access point?

Best regards,
Ian

Mini2440 - new flash chip - barebox update to last version

Dear Juergen and Sasha, 

I'have included you both given that you (Juergen) is the one working with the ptxdist version for the mini2440 and you (Sasha) are currently developing barebox.

Juergen is aware of a problem we have with the new mini2440 boards due to a change of the nand device because EOL of the previous part. Some adjustments need to be done to the nand controller to disallow partial programming because the new chip doesn't support it (and also have worse timings).

In any case, I am trying to solve it but also to update the barebox to its latest version (2014.11.0). I have already ported the env structure to the new format on barebox. When booting from nor (vivi) and then loading barebox on ram, I have no problems (beside the fact that I haven't implemented the new methods for barebox_update and have temporary solved it by including the update scripts from previous versions). However, when I try to load from the NAND nothing happens, no output in the serial port.

I'm trying to setup a arm debugger+opencd setup to see if I can find out what could be happening but for the time being, I don't have yet the required HW.

Surfing through the code in both releases (the one in last git respository for 2440, barebox 2011.05.0 and the last one available on barebox webpage (2014.11.0) I haven't found any major differences (that could cause this behaviour) besides one specific modification in lowlevel.S that replaces TEXT_BASE for TEXT_BASE - SZ_2M in the nand load routine. Do you now the reason for such a change?

Btw, i forgot to mention that I've also added the required modifications for proper management of 'big (>=128Mb) nands' using the patches from previous version as a base.

Can any of you provide some help regarding this issue? Specifically, have been there any attempts to update barebox to its last version for mini2440? Could any of you provide an inner point of view and some possible explanation for the impossibility to boot from nand?

Thanks in advance, 

Best regards, 

Carlos Leyva

BSP configuration for automount SD partition during boot-up

Hello Experts,

I have this partition on the SD card.
----
        Device Boot      Start         End      Blocks   Id  System
/dev/mmcblk0p1            8192       16383        4096   83  Linux
/dev/mmcblk0p2           16384     3162111     1572864   83  Linux
/dev/mmcblk0p3         3162112     3686399      262144   83  Linux
----

The /dev/mmcblk0p2 partition is the root partition while /dev/mmcblk0p3 is the spare partition.
Currently, I do manual mounting and formatting the spare partition and then added to fstab.

May I know how to configure the BSP so that the spare partition will automatically mount on first and onward
system boot-up?

Best REgards,
Ian

Problem with new nand flash

Dear Juergen and all, 

I am having problems with a new batch of mini2440 boards I have received from the manufacturer, the chip for NAND in this boards is K9K8G08U0E SCB0. I am able of writing data to the board (i.e. write the bootloader (busybox) and our linux image) but, as soon as i start using the board and filling up the space, more and more problems appear, making the boot time unusable (>10 mins) due to MTD error messages.

Previously, I have been working with boards with chips SAMSUNG 131 K9K8G08UOB PIB0 and K9K8G08OUOD SCB0 with no problem, same image, same bootloader. 

I have been able to locate a note regarding differences in the chips: http://www.phytec.de/fileadmin/user_upload/pictures/Support/LPN-134e_1.pdf

Are you aware of this situation? Have been it solved in latest OSELAS releases? If not, could you please give some guidance in the solution of this issue?

I'm stuck with old kernels because we could say the boards are in "production stage" so no big changes should be performed in order to avoid further problems and because in later kernel versions, as far as I remember, new issues arose as Sound not working.

Please let me know if any one can provide some light.

Best regards, 

Carlos Leyva

Upgrading OSELAS python package

Hi All,

The current python in OSELAS is python 2.6.6. I would like to run an application that requires python 2.7.6.
Therefore, I need to upgrade the version. I could not use the version 3.0 since it is unstable for that application.

Could anybody help me on this?

Thank you.
