I have my TIGARD (set to 3.3V and JTAG) connected to the router:
0 = TDO
1 = TDI
2 = TMS
3 = CLK
4 (WAN) = TRST_N
I have the ground on my TIGARD connected to the ground pin on the UART.
I have quadruple-checked my connections and they are all solid.
When I power on the router while holding the reset button it behaves as expected (the two LEDs nearest the USB port light up but none of the others do).
When I run openocd I don’t see any IDCode.
I connected my TDO to ground and I got the message “error at bit 0, saw 0x00” but when I connected TDO to 3.3v (I tried using the power barrel connector lead on the bottom of the board) I didn’t get a similar message.
As a side note, when I run openocd the LEDs for “2” and “3” light up. Not sure if that’s expected.
