Hi guys.
Have two CM4 with the same issue - eMMC storage died and needs replacement. Ordered two chips, soldered them onto CM4s - and I do soldering for a living, so don't worry about that - and I'am seeing the same issue on both while trying to flash them from a Pi 5 (or Windows):
Also the card seems to be detected by the board:------------
Are the chips faulty? Could be because ordered from AliExpress...
And can anybody tell me which replacement eMMC chips work 100% on CM4/CM5? Thanks a lot in advance, as always![:)]( "Smile")
