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

[muonkmu]

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 RPC server on ZCU104. However, if I try to upload “vta.bit” using “vta.program_fpga (remote, bitstream=“vta.bit”)”, the following error occurs.

Which version of TVM and Pynq are guaranteed compatibility Is there a solution for this?

Traceback (most recent call last):
  File "Simple_Matrix_Multiply.py", line 24, in <module>

Hi @muonkmu, I'm facing the same error, but with a newer pynq version:

Target : ZCU104 ( Pynq: 3.0.1) TVM v0.18.dev0 xilinx toos : vivado 2020.1

I haven't found information about which versions of TVM and Pynq are compatibility. What I'm going to do now is flash the SD with the pynq 2.5 image for the ZCU104, since in the tutorial they use that version for the PYNQ-Z1 card: https://tvm.apache.org/docs/topic/vta/install.html#xilinx-pynq-fpga-setup.

Anyway, did you find a solution for this?
