Hello again. I have just built the uClinux 2.4.x kernel for the Atmel AT91 (using Snapgear toolchain arm-linux-tools-20061213). I want to run this kernel with skyeye. I can successfully run the skye-testsuite AT91 (uclinux_cs8900a) with wonderful results. Warm fuzzy feeling and all that. The reason I am trying to rebuild the kernel is that the current testsuite example (uclinux_cs8900a) only has about 1.5MB RAM and my tests need around 13 MB RAM. When I switch to the kernel I just built, the memory address alignment no longer matches the config file values. I tried matching some values from skyeye.conf (below) to values in the 'make menuconfig' options for DRAM offset and size etc..., but I am not easily seeing the mapping between these values and what is present in the config file:
mem_bank: map=M, type=RW, addr=0x00000000, size=0x00004000 mem_bank: map=M, type=RW, addr=0x01000000, size=0x00400000 mem_bank: map=M, type=R, addr=0x01400000, size=0x00400000, file=./romfs.img mem_bank: map=M, type=RW, addr=0x02000000, size=0x00400000 mem_bank: map=M, type=RW, addr=0x02400000, size=0x00008000 mem_bank: map=M, type=RW, addr=0x04000000, size=0x00400000 mem_bank: map=I, type=RW, addr=0xf0000000, size=0x10000000 I am currently looking through the skyeye source (skyeye-1.3.2_rc1) for how the config file is parsed and what the mappings are, but this is looking to be an arduous task atm. If anyone has any good high level pointers on how to map kernel settings to match up with config file values or more directly how to increase the RAM avail to the skyeye VM it would greatly help out. I am a bit new to skyeye so there may something glaringly obvious I am as yet not aware of. Thanks in advance if anyone can provide some tips or documentation which clears this up. Looking around the web it appears there are multiple suggestions on toolchain and uclinux-dist versions from various sites, blogs and forums. I will probably try these out as well.
