I'm not sure if that's what's causing the stall, but I'm also wondering if I need to remove the images from the images folder to recompile the kernel after changing the config (removed the mouse and hoping that works)

NathanTP commented on May 29, 2024

The random part is normal, I doubt that's your issue. I would first make sure your image boots in Qemu and Spike (using the marshal launch command). If that doesn't work there's something wrong with Marshal (of course, cleaning and rebuilding is always worth a try, you never know. You may even "make mrproper" in boards/firechip/linux to be extra sure).

If it does work, then it's probably something to do with how you're using the VCU118. I notice from the output logs on your other post that it hangs after /init which means Linux itself probably booted OK. You can see what /init does in wlutil/initramfs/nodisk/init. I've never seen the stuff about mmc so it could be a Linux configuration issue (maybe it doesn't have the right drivers for your board?). One trick I've done for this stuff is to call "/bin/busybox sh" at the very beginning of the init script and mess around manually to see what's going on.

Vivado is generating a bitstream and eating a large amount of RAM so I'll have to try the QEMU thing after it finishes. I'll have to look at the Linux config and see what changes the VCU118 needs (I removed the mouse but I don't think that's gonna help with the SD card). I can't rule out these SD cards as being faulty either, I'm not sure where we got them from, but it seems to read them fine at first. I'll report back once I've tried QEMU and /bin/busybox sh

I can't seem to get qemu to run the no-disk version when running ./marshal launch br-base.json I get /mnt/Vivado_part/chipyard/chipyard/software/firemarshal/images/br-base-bin: No such file or directory Maybe I need to do something with the j flag for the launch command. I also wanted to try removing SPI_MEM and SPI_MMC stuff from the configuration in the kernel to see if that would fix my problem.

It's interesting that echo "Running FireMarshal nodisk init" never occurs. There's nothing in the second part of the partition. ~~https://mtekk.us/archives/guides/fix-linux-boot-halting-on-run-init-as-init-process/ suggests adding CONFIG_DEVTMPFS_MOUNT=y~~ This is already added to the config. marshal-config.yaml is board-dir : 'boards/prototype' ~~I'm assuming I would add this config to the config file under boards/prototype/~~

QEMU launches ok. The output doesn't look like the board's though. This is the disk version.

The mounting filesystem part makes me think I need to put something in the second partition.

Also I can't login. I tried root, no password and root, firesim. UPDATE: after digging around in config, I'm guessing the password is fpga.

NathanTP commented on May 29, 2024

You need to pass -d to launch to use the no-disk version, otherwise marshal tries to find the disk-based version. You should use "marshal -d launch br-base.json". This is also why you aren't seeing the modified init, as the name suggests, the one I linked is only for no-disk builds. Also, marshal doesn't expect users to change that so it doesn't track changes to it very well. You should delete the binary (e.g. br-base-bin or your-workloadname-bin) in images/ first to make sure it gets rebuilt with your changes to init.

The password should be 'firesim'. I recommend going through the quick start on the firemarshal docs first on a clean repo to make sure everything works, that should tell you everything you need. The only reason I can think of for the password changing is that you messed with br-base somehow. I don't recommend changing br-base directly, you can create a workload for your work and modify that while inheriting from br-base. See the marshal docs for more info there, especially the linux section.

As for the VCU118 stuff, I imagine that it has to do with requiring the drivers or perhaps Linux trying to mount things it shouldn't be. I wouldn't expect the linux boot to look the same since it's a different platform. Going through the boot process manually using the init trick I mentioned should help narrow it down. FireMarshal is really only tested on firechip on firesim or qemu/spike. Once you get this all working, I'd be interested in integrating it into marshal more properly.

michael-etzkorn commented on May 29, 2024

I did see that under boards/prototype/distros/base-workloads/br-base/buildroot-config the config sets the password to fpga. I'm not quite sure how to do the init trick your mentioning. wlutil/initramfs/nodisk/init has those echo commands (which don't show up) and I tried making the first line of that script exec /bin/busybox sh The boot still hangs. Although now I also don't see crng init done. I also removed the mmc and SPI configs which removed the SD card warnings, but it still hangs (and now doesn't show crng init done) so probably didn't do anything good.

When I launch the nodisk version in qemu, I get this output sh: can't access tty; job control turned off This has exec /bin/busybox sh at the top of init. Not sure what to do from the shell in QEMU. When I try running sudo fdisk -l, I get a segmentation fault. I'm going to remove the exec /bin/busybox sh and see if QEMU is also hanging.

Ah, I didn't notice you were using the prototype board. I'm less familiar with that one. @abejgonzalez might have some additional insights here.

Yea. I'm commenting on the other thread mainly. I'm not sure what the issue is exactly.

michael-etzkorn commented on May 29, 2024

The issue has something to do with CVA6. I'll try to set up verbose kernel statements to help diagnose the problem when I get the chance.
