Check failed: (fpga_buff_ != nullptr) is false

Hello!

I was wondering if someone encountered this error before:

Check failed: (fpga_buff_ != nullptr) is false

I am trying to execute a pretrained model on ultra96-V2, using VTA.

I setup TVM+VTA using the tutorials. I have image PYNQ 2.5 on the target device.

This error occurs even when running ‘test_benchmark_topi_conv2d.py’

Does someone have an idea? (screenshot is from the host side)

Thank you!
