[asterisk-embedded] Address to Flash uClinux to on AADK

[Wojciech Tryc]

Brian,
Your bootcmd points to spiboot, so you are actually booting your kernel from the serial flash.
spiboot=eeprom read 0x1000000 0x40000 $(readsize);bootm 0x1000000
It means:
read from a serial flash starting at 0x40000, read $(readsize) which is 0x444ac9 and then save it all to SDRAM at 0x1000000
then execute bootm (boot) from that address.

This would indicate that you need to save your image into the serial flash using the following commands:
eeprom write 0x1000000 0x40000 $(filesize)

Also, later please confirm that your "readsize" in printenv is equal to the size of the new image (you will get the size of your image while tftping it).
If not, then also execute

setenv readsize <size of your image in hex>
save

Please note, that I am not affiliated with Digium in any way, and I can not be resposnsible for anything if you endup corrupting your flash. The instructions above shoule work, but I would suggest to get formal confirmation from Digium boys.

Cheers,
Wojtek
