Yes, we've fixed this problem. The QEMU and real hardware addresses are different, but we've created different configs so that both are supported. > > > - Support the newest mips-sde-elf-gcc toolchain (Sourcery > > CodeBench Lite 2012.03-64) > > Does your current eCos code continue to build with the eCos mipsisa32-elf > toolchain (GCC 4.3.2)? No. Building with mipsisa32-elf hasn't been verified. I'll give it a try. > > Since we only focused on booting from Yamon and u-boot, we only tested > > RAM configurations.
