Hello genodians, While building sculpt for virt_qemu_riscv, I came across the following error, which I believe is related to dde_linux. Please have a look and kindly suggest the modifications required.

Please help me in understanding the problem and suggest some way out.

In addition to Christians comments. You will have to write assembly.

You could also use lwip [1] instead of lxip which works already on RISC-V.

Good luck,
