Together they make up piggy.img. - -The decompressor is built into the file decompress.o. It is turned into -the binary file decompress.bin, which is catted together with piggy.img -into the file vmlinuz. It can be executed in an arbitrary place in flash. - -Be careful - it assumes some things about free locations in DRAM. It -assumes the DRAM starts at 0x40000000 and that it is at least 8 MB, -so it puts its code at 0x40700000, and initial stack at 0x40800000. - --Bjorn |
