- When I try to boot Linux, it crashes during
uncompressing the kernel image:
=> bootm 100000 ## Booting image at 00100000 ... Image Name: Linux-2.4.25 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 1003065 Bytes = 979.6 kB Load Address: 00000000 Entry Point: 00000000 Verifying Checksum ... OK Uncompressing Kernel Image ... Error: inflate() returned -3 GUNZIP ERROR - must RESET board to recover
- Your kernel image is quite big - nearly 1 MB compressed;
when it gets uncompressed it will need 2.5 ... 3 MB, starting at address 0x0000.
But your compressed image was stored at 1 MB (0x100000), so the uncompressed
code will overwrite the (remaining) compressed image. The solution is thus simple:
just use a higher address to download the compressed image into RAM.
For example, try:
=> bootm 400000
