Hi,
I have built u-boot binary for 'qemu-system-mips -M mips'.
It is fine to run ths u-boot binary.
But the same u-boot binary does not run on 'qemu-system-mips64 -M mips'.
I do not understand what happends on the qemu-mips64 execution.
Is this a bug for qemu-system-mips64 ?
Or should I build u-boot binary by another configuration?
------
* u-boot building steps
(1) build the gcc 4.5 cross-compiler for mips from the source.
(2) build u-boot(2010.03) by the (1)compiler.
(3) copy the u-boot.bin to /usr/share/qemu/mips_bios.bin
* qemu(mips) execution command
$ qemu-system-mips -L /usr/share/qemu -d in_asm -nographic
* get /tmp/qemu.log
the execution seems fine.
* qemu(mips64) execution command
$ qemu-system-mips64 -L /usr/share/qemu -d in_asm -nographic
* get /tmp/qemu.log
the execution seems not fine. Something is wrong?
