Hi, there are 4 pins on the back of the Kioxia CM7 - does anyone know what these pins are?
It’s not just the CM7, a whole range of SSD’s have these. I suspect it’s a JTAG interface, for programming the internal controller chip. There’s power, ground, clock and a data signal. For an end-user, nothing to attach or investigate. If you bought a large capacity SSD (1+TB range) from Aliexpress and/or ebay for absolutely no money (or at least pittance against regular prices), the maker has manipulated the controller using this interface. On genuine Kioxia drives, that’s not an issue.
Like Dutch Master said, they are “for internal use only” aka, the manufacturer to use, not for is mortals…
Here I was thinking it was 1992 and a jumper could make the drive work with my HP motherboard…
