Subject: [U-Boot] AM335x : failure to boot SPL from NAND
Date: Thu, 14 Feb 2013 15:54:23 +0000 [thread overview]
Message-ID: <511D08AF.7070501@mimc.co.uk> (raw)
I'm trying to diagnose why our AM335x based CPU board (based on the AM335x Starter Kit) can boot SPL
and U-Boot from an MMC card, but is unable to boot from NAND (connected to CS0).
Following the TI wiki
(http://processors.wiki.ti.com/index.php/AM335x_U-Boot_User%27s_Guide#Flashing_images_to_NAND_in_SD_boot)
I:-
(1) boot from MMC
(2) erase the nand
(3) copy MLO from MMC into NAND
(4) verified it copied correctly (using crc32)
When I reboot the board in NAND mode, I get nothing on UART0.
If I reboot in MMC mode, SPL and U-Boot load correctly.
Can anyone give me some pointers on the boot sequence, and where I might look to help debug the
problem ?
Regards
Mark JACKSON
