128GB Toshiba Marvel ( Apple NVME ) no ID

[nicoalbrecht]

Any advice what to try on a 128GB Toshiba Marvel from a macbook.

SSD doesn't id in

1. DDI NVME
2. PC3000 via usb enclosure

controller seems to warm up to about 50 degress but shows 0 lba via usb enclosure and doesn't show up at all in DDI. Controller doesn't get warm in DDI NVME add on.

Any input welcome.

Check the supply voltage at the edge connector. Also check the DEVSLP pin. That's the power on/off control pin.

If you post a hi-res photo of your PCB, I could identify the voltage test points.
