AM3352: NAND boot issue

johnson lu

Part Number: AM3352

MCU is AM3352 300MHZ

the old NAND FLASH is MT29F1G08ABAEAWP, and the new one is MT29F2G08ABAGAWP-IT:G,

the system can work well using the old flash, but use the new one, have some probability to boot fail (about 30% ~ 40%). and if boot sucess, the system also can work well.

what's the problem? timing between NANDFLASH and BOOTROM code?

SYSBOOT config is: 0100000000001011

Hello,

Unfortunately, we do not support Linux 3.2.0. Please use the latest Linux available in our PSDK6.0.

Dear Krunal：

I think this issue is not matter of the linux version because the problem happend at the procudure of BOOT, (the BOOTROM of AM3352 process it, not the linux and uboot).

and if fortunate boot success,(there is still have some probability to boot sucess), the system is work fine, so I say linux and uboot can run well.

please reconsider this issue.

Hello,

I am wondering if you could please provide more information on the following items:

1. Are you able to replicate the same problem on multiple boards or just the current one?

2. I am wondering if it would be possible to probe the GPMC signals for any bus activity.

3. If the board does not boot, please connect to CCS and share the value of the control status register:

4. The hardware schematic you are currently using is based on what reference board design?

5. Since the issue is intermittent, are there any specific instances that triggers the board to not boot (like after board reset)?

Regards,
Krunal

Hello Johnson lu,

Have you resolved this issue?

My customer also faced similar booting failure issue with MT29F2G08ABAEA, and my issue was explained in below e2e.

Have you connected JTAG and found when issue was occurred exactly?

Is it possible to share your status?

Thanks and Best Regards,
