P1022: Issue in Booting from Parallel NOR Flash

senthil_k — Wed, 15 Jun 2016 07:22:56 GMT

Hi,

In Our Custom P1022 based board we are facing the following issues while booting u-boot from NOR Flash.

(We are using SDK 1.9 to build the u-boot image)

1. U-boot hangs after "jump_to_copy" function in "board_f.c" file, i.e. it is relocating to DDR (DDR size is 2GB) address 0x7fef0000 and hangs after that.

2. Some of the u-boot prints are not printing in the proper order, i had attached the u-boot console prints for your reference.

Please let me know, what might be causing this issue and how to debug further.

Original Attachment has been moved to: u-boot_log.txt.zip

Only Core0 has to be allowed to boot.

Check that cfg_cpu1_boot (LAD16) is asserted low during power-on reset.

Thanks ufedor, by allowing only Core0 to boot we are able to successfully boot from NOR Flash.

Now we are facing another issue, "ethernet is not consistent in NOR Flash Boot Mode". But in the same board with SDCard boot mode ethernet is consistent.

Please let me know is there any relation to ethernet and Flash boot mode.
