Run time failure, hang after the welcome message

[mongsim]

./riscv_em -f fw_payload.bin -d riscv_em.dtb

or

./riscv_em -f fw_payload.bin -d riscv_em.dtb -i myfilesys.img // ext3

Both have the same error and hang there forever!
Please advise. Thank you.

How did you build your image?

[mongsim]

I used this command to compile Linux.

./riscv_em_rv32_mmu_linux.sh

[mongsim]

I have an older version that does not have the—i option, and it runs well with the Linux image. It looks like it is not the Linux image issue by the riscv_em. Any suggestion?

[franzflasch]

The ramdisk feature was introduced by @redhog, and I haven't personally tested it. There may be a problem with the way you've built your ramdisk.

Edit: Sorry mabye I misunderstood. So with the latest master the emulator also does not even work with the initramfs?

[mongsim]

But without the -i it also failed at the same spot. The ext3 image is created uses this:

dd if=/dev/zero of=myfs.img count=204800
sudo mke2fs -t ext3 myfs.img
