Fatal Error message whilst running the 'hello' example

[LiamSkirrow]

Hi there! I'm attempting to run the hello example obtained from here, but am running into the following error message:

liam-skirrow:~/Documents/code/pulpissimo/sw/pulp-runtime/hello$ make all

I have built the riscv toolchain and have placed the 'hello' example at the path pulpissimo/sw/pulp-runtime/hello which I believe is correct, but would like to have that confirmed. Any pointers would be appreciated since I'm pretty stuck on this at the moment. It's also worth noting that I can compile test C programs with the riscv-unknown-elf-gcc compiler with no troubles, so I believe this is an issue with the Pulpissimo repo or the test 'hello' program I'm attempting to run. I would alternatively run with the full SDK instead but it appears that (according to the README) that the full SDK is not supported with the current release?

I'm running on Ubuntu 24.04.1 LTS in case that's relevant.

Thanks!

I wasn't totally sure where to place the pulp-runtime-examples/hello directory so I experimented with placing it at other locations, for example at the top-level project directory pulpissimo/ but this made no difference and I still see the same Fatal error: Broken assembler message. This makes it seems like an issue with the Pulpissimo directory itself perhaps?

Edit: it's occurred to me though that I probably shouldn't be using the latest commit since it's probably in active development, can you recommend a given release? I checked out v7.00 but still had some issues. If it turns out I've been building based on the wrong commit then I'll close this ticket.

I'm also having this problem.

I just tried to reproduce your problem on the master branch with the last commit but I can't. The hello example just compiles fine. This is the compiler version I used

$ riscv32-unknown-elf-gcc --version

Ok thanks for checking, when checking my compiler version it turns out I'm using the same version...

riscv32-unknown-elf-gcc (2021-10-30 PULP GCC v2.5.0) 9.2.0

Same as you.

I'm intending to use the v7.0.0 release anyway, so this isn't too much of a blocking issue for me, but I thought it'd be good to flag here anyway for others.

What pulp-runtime version are you using? Maybe that is the issue here

[dave-roo]

I've used the latest run-time.

I'm now installing Ubuntu 16.04 as this maybe the issue.
