hello
Our single board has the following questions:
OMAP-L138 set NAND8 start-up boot mode, all the object files, such as UBL, uboot, kernel and rootfs are placed inside the NAND flash, when the bootloader in the start-up phase, we tested the NAND flash signal integrity, such as the signal of EMIF_D0, found with half height level. Such annex.
Now back in NAND two kernel, there is a lot of kernel CRC validation failure in the use of the process, the need to re download in the UBOOT to return to normal. We suspect that there is a certain relationship and NAND signal integrity.
Accessories for the schematic, please help check(Please visit the site to view this file)
