M.2 Key B strange behaviour

Post by Yann Diorcet »

Hi,
I set a FM101-GL(https://fcc.report/FCC-ID/ZMOFM101GL/5603609.pdf) in M.2 Key B slot and I notice a strange behaviour. I can't tell if there is an issue on the fitlet side or the device side.
When I start the morning the filet (currently under developpment or side), the device is not detected:

Code: Select all

Issue related to the temperature? Is there something special to set in the bios to change from PCIe to SATA/USB device ?
