question occurs when i run qsort example program on e203

Actually，I tried to run a test which contains qsort func on hbirdv2 SoC, and finally the result was successful.
For your case，I suggest you may check whether the "ret" is executed correctly through checking more related signals at first.

qsort func is under the benchmark dir. whether you use objcopy to get verilog(bin) file from original riscv(elf) file. Then through tb.v , dump instuction into imem.
