Part Number: OMAP3503

Hello,

we are using KBOC board from KWKIBYTE where there is OMAP3503 and MT29CxGxxMAxxxxx pop memory from MICRON.

Sometimes boot fail. We have two logs : normal situation and boot fail.

normal situation.TXT boot fail.TXT

Boot is from NAND pop memory that copy software image to DRAM.

From the two log files, it looks x-loader/u-boot works ok, but kernel crash in non-working case.
For such an intermittent issue, one hypothesis is HW board related. We also noticed x-loader/u-boot version was from 2009.11-rc1.
We'd recommend to contact the board vendor to report the issue.

Have you heard some other pepole that experience this kind of problem ?

We have noticed that if the board started OK it continues to work properly,

so we suspect that is a problem related to application (or Kernel) software transfer from FLASH to DRAM

Some reference on NAND support in TI SDK: the first link is on u-boot, and the next one is on kernel:
software-dl.ti.com/.../Foundational_Components_U-Boot.html
software-dl.ti.com/.../NAND.html
Given that your x-loader/u-boot version was from 2009.11-rc1, and the board is from a 3rd party, The above links would serve as reference.
