For that matter, I patched my kernel 2.6.15 with the zImage_2_6_10.patch from Popov. In the arch/mips/boot/compressed/au1xxx/Makefile, I have set: 1) RAM_RUN_ADDR=0xa0300000, which is the value got from the umon's APPRAMBASE environment variable. 2) AVAIL_RAM_START=0x80500000 AVAIL_RAM_END=0x80900000 3) LOADADDR =0x80100000, which is the same value I have set in an entry for this board in arch/mips/Makefile. I can compile and link the zImage with home build gcc cross tools, based on gcc-3.4.4 and glibc-2.3.4 . When the (binary) zImage is decompressed on the target, I get these messages: zImage: size=680372 base=0xa0300000 loaded at: A0300000 A03A4000 zimage at: A0306180 A03A3EE1 Uncompressing Linux at load address 80100000 and then the target resets. This zImage is very small, so the decompressed image is not going beyond the AVAIL_RAM limits. Would you have any guess on what is going on? I have looked for this information the list through, but anyone seems to have had this problem before. Thanks for any comment. -- Carlos Mitidieri SYSGO AG - Office Ulm Lise-Meitner-Str. 15 D-89081 Ulm
