  hello,   my board base on  9m10g45, but mine don't work.   version ----  2013 lastest .  Would you please tell me why??   I will appreciate your reply.

Please configure your MUA to wrap at about 80 chars per line.

These are all at91bootstap outputs. It breaks when handing over from
at91bootstrap to u-boot. It is possible that your u-boot really break
here, but cause we do not see any output from u-boot (the version line)
it is likely that you have mis configured at91bootstrap here. However it
may be some mis misconfiguration in u-boot too. The relevant parameters
are CONFIG_SKIP_LOWLEVEL_INIT, CONFIG_USART_BASE/CONFIG_USART_ID. Please
check that these are setup correctly.
Regarding the at91bootstrap please check the following questions:
 * Can you verify, that you have written your u-boot binary (the *.bin
   file) at offset 0x20000 into your NAND?
 * Can you also verify that your u-boot image is not bigger than
   192 kBytes?
 * Have you checked that the ECC mechanism used when writing the u-boot
   into NAND do match the oob layout the mechanism used to read the
   u-boot out of NAND?
 * Can you please check that you have more than 64MiB SDRAM connected
   and correctly initialized by at91bootstrap?

this is a common problem for separate first stage bootloader
(at91bootstrap) and second stage loader (u-boot). You always need to
manage the dependencies between both by yourself.
I'm looking forward to enable u-boot to act as a first stage bootloader
for at91 too (keyword SPL in u-boot). Hopefully we get a full boot
solution from one source blob then which is able to manage those problems.
