Hi again megavolt85, sorry for the spam.
I've got the SPI memory but of course I don't know if it is working, I've tested the latest firmware with a new cable I've used before with a DC controller, the cable works fine with the DC controller.
I tried multiple pills even with the CH32 clone, no luck, I will try to check with a borrowed oscilloscope just to be sure nothing is wrong, my DC is a japanese Ugo Denshi version, just in case it matters.
I've soldered the SPI memory with your specs but I'm unable to test it currently. Maybe something is wrong with my Blue Pills, it is difficult to check if it is a clone or a real one, but I've seen on this thread pics some clones working.
