Original question:

AM625: am625 ,How to display the logo in U-boot

AM3352: The AM335X platform switched from NAND to SD card boot. Burning the NAND image works normally, but the system cannot boot from the NAND.

Part Number: AM3352

Hello, we replaced the NAND on our AM335X platform (now SkyHigh S34ML02G300TFI000, previously MT29F2G08ABAEAWP-IT:E). Booting from an SD card to flash the NAND works normally, but we cannot boot from the NAND itself. There is absolutely no output on the serial port. Is there a support limitation with the boot RAM?

OOB is 128 bytes

    Is there any progress at this time?

    I will have to check more, but according to the thread you posted, I'm afraid if this was not implemented in AM62 ROM, then there is a low chance it was in AM335's ROM.
