I know nothing about where is kindle 8 find kernel at first, so I don't know where should I write uImage, but, I found some interesting log in the first start log:
Code:
Hit any key to stop autoboot: 0
mmc1(part 0) is current device
FRED::: EXTCSD177=0, 179=48BOOTing from mmc ...
mmc1(part 0) is current device
MMC read: dev # 1, block # 720, count 28672 ... 28672 blocks read in 320 msec: OK
MMC read: dev # 1, block # 520, count 256 ... 256 blocks read in 6 msec: OK
Wrong Image Format for bootm command
ERROR: can't get kernel image!
uboot >
MMC read: dev # 1, block # 720, count 28672 ... 28672 blocks read in 320 msec: OK
MMC read: dev # 1, block # 520, count 256 ... 256 blocks read in 6 msec: OK
I think, it must find system in dev # 1, block # 720, count 28672, kernel in dev # 1, block # 520, count 256, so, block 520address=0x208, That is!
