The M.2 socket on the Edge V supports 4 full-duplex lane PCIe 2.1:
The M.2 socket on the Vim3 supports PCIe 2.0 (one lane ), and M.2 2280 NVMe SSD, USB 2.0, I2S, I2C, ADC, 100M Ethernet PHY interface, GPIO
M2X compatibility matrix states:
VIM3 (Full-Featured, PCIe x1 Lane)
Edge-V (SSD-only, PCIe x4 Lane)
Which means when connecting M2X to Edge-V the LTE module on the M2X will not be recognized.
Can anyone please explain where this limitation comes from?
Does that mean the issue is with USB2 support on the SBC side?
Or does the problem reside with the LTE modules themselves?
