trabucayre_florent_: I try to adapt zybo_z7 to use litex with my redpitaya.10:35
trabucayreAfter some (ugly) modifications the bit is produces, with bootgen I produce the bit.bin and (finally) through linux and fpga_mgr I load the bitstream.10:35
trabucayregateware is working and linux don't freeze (the bitstream is correct with ps7 ip present)10:36
trabucayreNow I try to read/write using devmem but I'm unable to change something. After some read it's seems CSR base addr is 0x8200_0000 (is somewhere in GP1 address space), if I try to read/write, the system freeze (I suspect GP1 not initialized). Have you some advice to correct this (xci configuration to modify) ?10:36

_florent_trabucayre: could you try with https://github.com/enjoy-digital/litex/commit/3ff1bcaf0526929f9972bb94024cb265a61864af?19:38
tpbTitle: cpu/zynq7000: set csr map to 0x00000000. · enjoy-digital/litex@3ff1bca · GitHub (at github.com)19:38
_florent_it will force the csr map to 0x00000000, you should then be able to access the CSR at the base address you specified here: https://github.com/litex-hub/litex-boards/blob/master/litex_boards/targets/zybo_z7.py#L6619:39
