Linux boot get stuck #23

Closed mathmax12 closed 5 years ago

mathmax12 commented 5 years ago

I post this issue under Ariane but can't find a way to delete it there. Can I get help with this issue? https://github.com/pulp-platform/ariane/issues/309

Thanks.

Moschn commented 5 years ago

Can you try to use the linux image from the releases?

mathmax12 commented 5 years ago

The released Linux image(4.2) works. Is the flow used for this image is different from the one in the readme of ariane-sdk? I'd like to make this image-building flow work in case I need to modify the kernel.

Thanks

Moschn commented 5 years ago

No, the build flow is the same. I have no idea why it would not work. Maybe @zarubaf can help?

mathmax12 commented 5 years ago

Here is a difference between the prebuilt of Ariane 4.2 and the one using the built flow. after copying boot image ................................ done! I didn't see the bbl loader. why?

Hm, no idea actually. Especially as it boots relatively far.

mathmax12 commented 5 years ago

Thanks anyway! I switched to lowerisc-chip and found that the build bbl works.

@mathmax12

Hi, I am trying to load bbl with gdb to Ariane on a FPGA and hope you or someone can give me some pointers. DDR on my board starts from 0x200000000 for 8GB. I have modified PAGE_OFFSET to 0xfffffffe00000000 (2's complement of 0x200000000) when I built vmlinux. After I built bbl, I loaded bbl to address 0x280000000 with riscv64-unknown-elf-gdb. I wonder what should I do next to have it run, to copy code to 0x20000000, etc. Thanks a lot in advance!
