Fyi, I figured out how to make the flash config logic work properly for the FTDI (xFlasher, Squirt programmer)
needs bugfixing and some tweaks but overall I was able to get that implementation working - no more need to select nand sizes every time, it only asks if it encounters a weird.
Update will come out before the xFlasher releases publically but I want to wait as long as possible to avoid constant updates...
Kind Regards,
Josh
