iMX25PDK getting RESET

[metalheart]

Hello people,

I am using the iMX25PDK three stack development board for developing QT applications.

So, to get started, I downloaded demo images from Freescale site ( L2.6.31_09.12.00_SDK_SOURCE ) to test the basic functionalities of the board. It was working fine for a few days, but since yesterday, it is getting RESET on its own while booting.

Once, I got the redboot prompt (by luck I guess...), so I loaded the kernel and tried to boot the board. Again the board got reset in the middle of booting. I gave attached an error log of the same with this (reset_error.txt, line 402).

I am a little new to this stuff, so don't mind if it is a trivial issue, pls guide me.

So, pls do shed some light on this by sharing your opinions. Thanks in advance...https://community.nxp.com/discussions/699-reset_log.txt" target="_self

In the "reset_log" I see the message about I2C problem.
Perhaps the following helps :

Hi Renato, thanks for replying...appreciate it

I have already gone through the LTIB image generation process to generate my own binaries, I have only to test them.

And, to add to my worries, new issue has developed. The board has stopped functioning correctly since yesterday, I mean first it was getting reset during boot, but now it not booting anything. When I try to connect the target to Advanced ToolKit (ATK) for programming, it is asking me to reset the board, not able to connect (neither USB not UART). Now I think it is the internal on-chip bootloader that is responsible for making the connection, so I seriously think this is right down to cpu level (but i hope i am wrong... :X ).

When I power on the board and try to see what,s coming on serial port, its all garbage, and the strange thing is that this happens regardless of whether the board is in boot mode or programming mode.

Anyway, I am trying to find the datasheet of iMX255, found a pdf but its not detailed enough...just timing considerations.

I'll post the solution back here when I crack it...

May be your PMIC (power management IC) on CPU board is not working. Try to look for the required voltages on the input and output through PMIC.

Hello Aditya,

Please download the IMX25_0912_SDK_LINUXDOCS_BUNDLE here:

http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=IMX25PDK&fpsp=1&tab=Documentation_Tab

This is the documentation bundle for the BSP, you can follow the document  “pdk2009_12_imx25_Linux_UG.pdf” to guide you thru the image generation process.

Regarding your log, the "bootp" indicates that Linux is waiting an IP from a server, did you select start networking on LTIB? Is the eth connected during boot?
