Hi Duan, Unfortunately the PI4 doesn't work out of the box with the SNAP board. - Aaron Parsons did some debugging on this and found that the GPIO base address changed on the PI4, and needs to be updated in the JTAG header file.
I think the required fix has been pushed to a branch that you can try here: https://github.com/jack-h/katcp_devel/tree/rpi-devel-casperfpga/tcpborphserver3 Cheers, Jonathon On Mon, 11 Apr 2022 at 04:12, duanxuef...@xao.ac.cn <duanxuef...@xao.ac.cn> wrote: > Hello,CASPER！ > I am trying to control SNAP1 with raspberry PI 4.
