Hi everybody!
I now have U-Boot running fine on my self designed, PPC603e-based board. In the next step I want to try to start a Linux kernel image. For the generation of it, I use the ELinOS embedded Linux distribution. This creates me the kernel image (v2.4) + the initial ram disk. For debugging I use the BDI-2000 JTAG debugger.
First, I start U-Boot from flash memory, located at 0xff800000. After it runs, I load the kernel multi-image to RAM, which is located from 0x00000000 to 0x007fefff, at address 0x00600000. Using the 'imi 0x00600000'-command, i get the output:
=> imi 0x00600000
## Checking Image at 00600000 ... Image Name: Multi-File Image Created: 2005-02-24 14:27:59 UTC Image Type: PowerPC Linux Multi-File Image (gzip compressed) Data Size: 1237870 Bytes = 1.2MB Load Address: 00010000 Entry Point: 00010000 Contents: Image 0: 333090 Bytes = 325.3 kB Image 1: 904766 Bytes = 883.6 kB Verifying Checksum ... OK
=>
Then I try to start the image:
=> bootm 0x00600000
## Booting image at 00600000 [ same as command before ]
Umcompressing Multi-File Image ... inflateInit2() returned -4 GUNZIP ERROR - must RESET board to recover
What could be the problem? I calculated the sizes and i am _nearly_ sure, that nothing is overwritten.
Hopefully, Sebastian Häpe
