05:30 <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! OSError: Unable to find any of the

05:34 <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.

05:35 <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

05:36 <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"

05:41 <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

05:42 <Guest20> I see. Make sense. I will try a laptop later. Thanks trabucayre!

05:43 <trabucayre> You can try to install riscv toolchain using pkg manager

05:46 <Guest20> I'm new to litex. Where can I find the riscv toolchain pkg manager info? Is there a link? Thanks!

05:49 <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

06:00 <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!

06:03 <trabucayre> ;-)

12:12 <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

14:18 <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.
