4 years ago Hi Leo, Thanks for trying LowRISC. The first error is probably because/bin/sh is aliased to dash instead of bash. The second error is more mysterious and may be because a different version of device tree compiler than the one expected is installed. This could be due to running on an OS different to the supported one. To debug, run the assembly stage manually instead of in a pipe.
The third issue with Debian Ethernet, I am not clear if you do not want Ethernet or you have it and it doesn’t work. You can either use buildroot as recommended in the instructions, or chroot into the startup disk on your workstation to disable unwanted services.
Regarding the file layout, this closely follows the Ariane structure which was introduced in this release. It is supposed to reduce the number of independent stages needing to be run.

I thought there may be some mistakes in the Makefile, so I deleted the "&" after "|". Then, I run the make nexys4_ddr_rocket again. This time, the |& thing was OK, but another error occurs:

It seems that the file: home/leo/makess/lowrisc-chip-ariane-v0.7/fpga/src/etherboot/Makefile has some mistakes around the -xassembler - -o, but I don't know how to fix it.
I also found that the 0.7rc2 repo structure seems very different from the 0.6 one, could you please explain a little bit about it?
Another issue: the binary releases of 0.7rc2 have a problem of don't have an ethernet connection(I step-by-step followed the quickstart guide). While booting, debian says: FAILED TO RAISE NETWORK INTERFACE. And this not just happened to me, my other friend has the same problem, I think it is a general issue. 0.6 doesn't have this issue.

But the rootfs.tar.xz of lowrisc 0.7 rc2 is beyond 2G after extraction, so 2G is not enough for 0.7rc2 (but it's enough for 0.6), the makefile needs a little modify. I give 4G for the Linux partition using the following partition table:
I believe that it will be better to correct the Makefile in order to avoid 'No space left on device' error, this will be more friendly to beginners.
