HI, @b-camacho and all PYNQ-based VTA users,
As I wrote above, I got runtime-error when I fixed cmake script and ran VTA on Xilinx device (ultra96).
I don’t know whether the error is occurring only in my environment or not, so could you let me know you succeeded to run VTA test-script or not?
My trial was ,
- checkout 36a83c7 (Mer 21, 2020)
- fix VTA.cmake
- build
- run apps/vta_rpc/start_rpc_server.sh on PYNQ device
- run matrix_multiply.py on HOST
And the error on PYNQ side was:
INFO:RPCServer:connection from ('192.168.174.8', 55040)
INFO:root:Skip reconfig_runtime due to same config.
INFO:root:Program FPGA with 1x16_i8w8a32_15_15_18_17.bit
