Hello,
i am trying to boot from NOR flash in AM1808 EVM, i have followed the next steps:
I have programmed ubl and u-boot in NOR Flash and it looks to boot Ok, u-boot version is 2010.12 and i have build it using Arago Toolchain in last SDK 5.03
Booting TI User Boot Loader
UBL Version: 1.65
UBL Flashtype: NOR
Starting NOR Copy...
CFI Query...passed.

Now i protect off and erase NOR to load uImage
U-Boot > protect off 0x60080000 +232b84
.................. done
Un-Protected 18 sectors
U-Boot > erase 0x60080000 +232b84

Erased 18 sectors
Next i load the kernel in NOR after loading uImage in 0c0700000
Using DaVinci-EMAC device

U-Boot > cp.b c0700000 60080000 232b84
Copy to Flash... Flash not Erased
Is it Ok the message Copy to Flash...Flash not Erased?
Last i set bootcmd and boot
U-Boot > setenv bootcmd 'cp.b 60080000 c0700000 232b84;bootm'
U-Boot > boot

ERROR: can't get kernel image!
If from u-boot i download uImage from tftp directly to 0xc0700000 and boot, the booting is OK, so i guess that uImage is not being flashed Ok in NOR. Pls. could you help me?
Thanks in advance
Alberto
