JTAG pins might dissappear from the board?
There is a video here "Pico-DirtyJTAG: Cheap JTAG Programmer! Raspberry Pi Pico for Lattice ECP5 + Icestudio":

- tverbeure 18d agoI have some HUB75 boards where the JTAG pins are covered with solder mask or only available by scratching solder mask from non-descript traces. These boards are programmed in production with SPI pins or assembled with preprogrammed PROMs.
