| Guest20 | I'm trying to install linux-on-litex on my RaspberryPi by following https://github.com/litex-hub/linux-on-litex-vexriscv#readme. I made all the way to run ./sim.py, but I hit "OSError: Unable to find any of the cross compilation toolchains:" Following log shows the error and $PATH setting. Any suggestions? Thanks!

| trabucayre | Guest20: you need to update to PATH to add riscv directory | 05:34 |
| Guest20 | Don't know why "echo $PATH" output doesn't display here, but riscv64-unknown-elf-gcc-8.1.0-2019.01.0-x86_64-linux-ubuntu14/bin path is listed in $PATH. | 05:34 |
| trabucayre | export PATH=$PATH:/home/pi/proj/litex/riscv64-unknown-elf-gcc-8.1.0-2019.01.0-x86_64-linux-ubuntu14/bin | 05:35 |
| Guest20 | Give it another try. Here is my current setting pi@raspberrypi:~/proj/linux-on-litex-vexriscv $ echo $PATH | 05:35 |
| Guest20 | Still does show. Let me add a quote around the ourput. "/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/home/pi/proj/litex/riscv64-unknown-elf-gcc-8.1.0-2019.01.0-x86_64-linux-ubuntu14/bin" | 05:36 |
| trabucayre | I'm dumb: you use an RPI (ie arm or arm64 architecture) and try to execute riscv64 toolchain built for x86_64 architecture | 05:41 |
| trabucayre | you can't do that | 05:41 |
| Guest20 | I see. Make sense. I will try a laptop later. Thanks trabucayre! | 05:42 |
| trabucayre | You can try to install riscv toolchain using pkg manager | 05:43 |
| Guest20 | I'm new to litex. Where can I find the riscv toolchain pkg manager info? Is there a link? Thanks! | 05:46 |

| trabucayre | If you use RPI I assume it's debian like distribution: so something like sudo apt install cpp-riscv64-linux-gnu do the job | 05:49 |
| trabucayre | or gcc-riscv64-unknown-elf | 05:49 |
| Guest20 | It doesn't work for me. I will table this for now and turn to a normal x86 platform platform to try it out. Thanks for the help! | 06:00 |

| shorne_ | somlo: in litex-rebase, do you mind squashing each driver into a single commit? It makes it easier for mee to cherry pick onto mainline and also look at patches | 12:12 |

| dasdgw | hi, I want to use jtagbone for an altera target. So I added 'self.add_jtagbone()' to my target file which lead to a 'NotImplementedError'. I than modified add_jtagbone in soc.py to use JTAGAtlantic instead of JTAGPHY. After that I can use jtagbone as expected. Is it possible to use jtagbone with altera/intel targets without modifying soc.py? Feels like I'm doing it wrong. | 14:18 |
