I had to add some WATCHDOG_RESET() calls to LzmaDec.c because my device has a slow mpc823 CPU. However booting does not continue and I do not know why. > Un-Protected 63 sectors > ## Booting kernel from Legacy Image at 00500000 ... > Image Name: Linux LZMA > Image Type: PowerPC Linux Kernel Image (lzma compressed) > Data Size: 589824 Bytes = 576 kB > Load Address: 00000000 > Entry Point: 00000000 > Verifying Checksum ...

Attached you will find the config used to compile U-Boot. I started with CONFIG_SYS_LOAD_ADDR 0x200000 and increased it to 0x500000, but it did not help. I suppose decompressing a LZMA-compressed kernel takes more RAM, my box has 64MB which I think should be enough. The decompression should work with 32MB RAM as well as this is the standard amount. I am not an expert when it comes to handling a Linux kernel at boot time so pointing to lots of howto's is appreciated ;) Cheers, rhabarber1848 -------------- next part -------------- A non-text attachment was scrubbed...
