Take into account that the u-boot.bin in the last release must be stored on the NOR flash of your board - the board has both NAND and NOR flash. The DIP switch on the main board and on the Debug extension must be set to boot from the NOR flash.
Yes, I just realized that it might be the cause. I our hw doesn't have NOR, only NAND.
Well, the mx35pdk (aka mx35_3stack) has always NOR flash, so far as I know. Do you mean you are running a custom board ?
I looked in mx35pdk.h config-header, but couldn't find place where to config U-boot for NAND. I'm compiling U-boot myself and not using precompiled binary.
There is no such a simple CONFIG_ to switch them and you must add support for it.
To boot with NAND, you have to use the SPL mechanism. This set up the RAM and copies the u-boot image from NAND to RAM. NAND driver for the MX35 is supported, so it should be not a big effort to add the board.
