Olimex GateMateA1-EVB + Onboard UART?

[dettus]

Hello!

So, I do have an Olimex GateMateA1-EVB.
Currently, I am using the PMOD to attach my design's UART to the outside world.

But I just discovered that there are Pins marked DBG_UART_TX and DBG_UART_RX connected to the RP2040.
Are they accessible through the USB connector?

Currently, I am thinking about a design like this:

Code Select Expand

always @(posedge clk)
begin
    DBG_UART_TX<=DBG_UART_RX;
end
P.S.: I currently do not have physical access to the board, so I am asking, instead of trying.

DBG_UART_TX <= DBG_UART_RX would probably drive the RP2040 TX line from the FPGA side, maybe assign DBG_UART_RX = DBG_UART_TX; instead
