I notice the csignals lookup table has incorrect definition of the op1sel and op2sel signals:
JALR -> List(Y, BR_JR , OP1_RS1, OP2_IMI , ALU_X , WB_PC4, REN_1, MEN_0, M_X , MT_X, CSR.N), Should be:
JALR -> List(Y, BR_JR , OP1_RS1, OP2_IMI , ALU_X , WB_PC4, REN_1, MEN_0, M_X , MT_X, CSR.N),
JALR -> List(Y, BR_JR , OP1_X, OP2_X , ALU_X , WB_PC4, REN_1, MEN_0, M_X , MT_X, CSR.N),
I have not been building riscv-sodor so I can imagine this makes no difference, the ALU result is discarded for JALR anyway.
It just confused me for a while as I'm writing my own Sodar 1-Stage in SpinalHDL and peeking at your csignals table to check I had got mine right.

that's fixed here librecores@7d34a96
Sorry, something went wrong.
