Hi,
I am burning images into nand flash with nand flash writer, both boot_ti.bin and apps_ti.bin. It can boot up from nand.
But when I tried to burn images with u-boot, it can't boot up.
The detailed information as follows:
(1) boot over uart
using u-boot-spl.bin and u-boot.img, and it can boot up.
(2) Then with u-boot command, such nand erase, nand write, burning image into nand flash.
a) burning boot_ti.bin into nand flash 0x0 offset
mw.b 0x82000000 0xFF 0x20000
loadb 0x82000000
download boot_ti.bin into 0x82000000 with Kermit
nand erase 0x0 0x20000
nand write.i 0x82000000 0x0 0x20000
b) burning apps_ti.bin into 0x80000 offset
mw.b 0x82000000 0xFF 0x40000
loadb 0x82000000
download apps_ti.bin into 0x82000000 with Kermit
nand erase 0x80000 0x40000
nand write.i 0x82000000 0x80000 0x40000
It's said that there is ECC(BCH8) in u-boot, the same as ROM CODE and nand flash writer's.
But why it can't boot up?
