Running Linux (on LiteX)

[Marco Brohet]

Hi all,

Sorry for asking this noob question, but I was searching for an open-source RISC-V core on which I can run Linux on a Genesys 2 Kintex-7 FPGA. I found the BlackParrot processor and I was trying to find out how to get Linux booting on the FPGA.

I found this Github repo [1] that seemed promising. I got Linux booting (yay!), but then buildroot asked me for user/password credentials that weren't listed... The YouTube video [2] does show "root" to be the username, but "root" as password didn't work.

Is one of you aware of the password? And is this indeed the most current way to get Linux booting on BlackParrot (on FPGA)?

Cheers,

Marco

Hi Marco,

I am happy to hear that you could boot up Linux based on the instructions in README file. The github repo that you refer to is actually the correct one. Since LiteX and BlackParrot are constantly evolving, I pile up all compatible versions (BP, LiteX, Linux) under that branch. 

The password is blackparrot if I remember correctly :). Please let me know if that works fine. For any other questions related to BP in LiteX, you can use this group and I will be happy to help.

Thanks,

Sadullah

Hi Marco,

Note also that OpenPiton also supports BlackParrot, perhaps a more recent version. Litex and OpenPiton have different memory systems and supported devices.

Hi all,

Thanks for your answers! The password 'blackparrot' worked indeed, so I made a little pull request to update the README.md with this information: https://github.com/black-parrot/litex/pull/1

And I'll be sure to check out OpenPiton too.

Cheers,

Marco
