AM3352: Boot issues

Angelo

Part Number: AM3352

Dear all,

i am working on a CPU marked SN150752100BZCZA, i cannot find the whole code in any datasheet, but i am supposing (from the 100BZCZA) it is an AM3352.

I have 2 issues,

1) setting bootstrap configuration for SD boot, using an SD created by sdk create-sdcard.sh, booting i see abt 120msecs of SD clock, but then a fall back to UART boot happens (i get xmodem CCCC sync). MLO and u-boot.img are in the proper fat partition, as created by SDK.

2) trying UART boot, xmodem 1k upload stops at 52224 bytes, so i cannot complete spl u-boot upload (while the CPU should allow 109KB).

If any help, welcome.

Regards

Angelo

Hi Angelo,

Are you using a custom board or a TI board?

Well, i started working on a board where i still have to receive precise information, by the way, from the fact that ROM bootloader is not executiong any code, and from the strange code marked on the cpu, i suspect it is an HS-device and not a GP so it would explain all.

Could someone confirm the code SN150752100BZCZA is an HS-device ?

Hi Angelo,

It's been a while since we've heard from you. I'm assuming that your issue is fixed. If not, you can respond to this thread.
