These days I am really very busy preparing the GRE and Tofel test. Moreover I have to work to support my life. So I have to spend less time on qemu-loongson. Anyway, there are progress these days. Rewrite the GPIO I2C emulation for gdium. Now it is more clear than before. add st4180 rtc emulation to qemu add stds75 temperature sensor emulation to qemu change a little in uart emulation to satisfy pmon’s uart probing process fix a little bug in pflash_cfi02.c fix gdb stub bug in qemu to support mips64 Follow is the uart output of qemu-loongson. kill-bill:/home/root/sdd/gdium/qemu-loongson/mips64el-softmmu# ./qemu-system-mips64el -M gdium -pflash gzrom.bin.gdb -nographic -S -s Register sst39vf040  size 80000  at offset 08800000 addr 1fc00000 'pflash0' 80 devfn 70 unassigned_mem_readl Unassigned mem read 000000001fbffffc unassigned_mem_readl Unassigned mem read 000000001fbffffc new_sm502_mm_io 7000000 pci_mem _base 10000000 PMON2000 MIPS Initializing.
