No response on UART on ice40hx8k-evb

[r4d10n]

I tried loading the ice40hx8k-evb board files. The LEDs are blinking and I'm using just the UART for IO, without VGA/PS2.

No response on UART with screen and miniterm (--rtscts /dev/ttyUSB1 115200). Even with CAPS entry.

Tried setting the ps2_select to 1'b0. Still no luck.

Anything else to check ? How do I check if CTS is willing ?

If you attach a button (or tap a jumper) to F1 and GND and press it, it should toggle between them.

Pin G1 much that same if you put a button will be the system reset.

It uses hardware CTS for the UART need to make sure the driver supports it. I have issues with MacOS drivers not supporting RTS/CTS.

If you reset it you should get an @
