Just tested v10 on mx31pdk.
As reported in v9 I start to get reboots and never reach the prompt.
Then I disabled watchdog options in mx31pdk.h and I get the following:
U-Boot 2013.04-rc1-14135-gab21c72-dirty (Apr 09 2013 - 09:23:01)

(Board hangs here).
When I tested v9 and removed watchdog support I was able to get into the U-boot prompt.
I just added "#define DEBUG" in arch/arm/lib/board to start debugging this and for my surprise I can reach the prompt now:

I remember to have added "#define DEBUG" in v9 as well, so looks like the behavior between v9 and v10 is consistent.
Now we need to understand why the prompt is not reached without ""#define DEBUG".
Can you try different values for the following configs in mx31pdk.h?
- CONFIG_SYS_NAND_U_BOOT_SIZE
- CONFIG_SPL_TEXT_BASE
- CONFIG_SYS_TEXT_BASE
- (CONFIG_ENV_OFFSET)
- (CONFIG_ENV_OFFSET_REDUND)
I would try:
- 0x40000 for CONFIG_SYS_NAND_U_BOOT_SIZE
- 0x86000000 for CONFIG_SPL_TEXT_BASE
- 0x87000000 for CONFIG_SYS_TEXT_BASE
I have retrieved your previous test trace: --- U-Boot 2013.01 (Feb 22 2013 - 16:25:48)
CPU: Freescale i.MX31 rev 2.0 at 532 MHz. Reset cause: POR Board: MX31PDK DRAM: 128 MiB
(hangs here). ---
So it does not hang at the same step.
Can you try to disable CONFIG_CMD_NET or to comment out eth_initialize() in arch/arm/lib/board.c? Do you know if something has changed in this function recently, or if there is something about it that has not yet been merged in the arm tree?
