[VTA, RPC] Can't upload custom bit file by RPC on ZCU104

Troubleshooting
#1

I am testing VTA in the following environment.

  • Target : ZCU104 (pynq 2.7)
  • Host : ubuntu 20.04 + TVM(v0.16,dev0)
  • xilinx toos : vivado 2020.1

I successfully synthesized the “vta.bit” file for ZCU104, and successfully launched the PRC server on ZCU104. However, if I try to upload “vta.bit” using “vta.program_fpga (remote, bitstream=“vta.bit”)”, the following error occurs. Is there a solution for this.

target : zcu104
