Loading 3D model… large boards can take a moment.
On V1 we have FTDI to FPGA working and we can upload bitstream to FPGA, serial passtrue is also working. For some reason it was hard to put ESP32 into bootloader mode, and I was not able to load micropython while shiled was connected to FPGA. After doing that directly (bricking pins on shield FTDI TX > ESP32 RX, ESP32 TX > FTDI RX, GPIO0 > GND) I have succesfully loaded micropython on ESP32. WROOM is still not perfect fit as it has low memory. WROWER can access shared SD card, and flash FPGA over WIFI.
