Re: [U-Boot] u-boot fails to uncompress a "gzip'ed -9" kernel

Hi Tor, Did I ever respond to your email, I forgot. Anyway it's nice to see others have the same problem also. The root cause of this has been found, did you see this: It's a CPU memory cache problem (I could have known). details: Scott Wood wrote: > This board currently sets DBAT6 to cover al

Hi Norbert, I missed the start of this thread. So my apologies if im barking up the wrong tree :) We had problems uncompressing zImages on our 8313 board. But always suspected some memory timing issues, or perhaps some strangeness in 8313. I tracked our problems down to a specific line in lib_ge

This is a MPC8313E-RDB board problem. We have 2 REV A4 boards. I can reproduce this problem on both of the MPC8313E-RDB boards with any version of u-boot with a compressed file which contains 1 or more dynamic codes blocks and a final fixed codes block. I have a 5k gzipped file for which the pro

A certain powerpc 2.6.28 kernel (which is by default compressed with gzip -9) fails to load with u-boot v2008.10. It results in a machine check stop. I'm testing on a MPC8313-RDB. Btw. the linux-2.6.28/arch/powerpc/boot/wrapper script takes care of compressing with "gzip -9". On my host linux pc
