We have troubles of getting RAK 5146 USB variant working (or even recognized by kernel) on Industrial x86 Linux PC.
HW: OnLogic ML350g-10
OS. Ubuntu 20.04 LTS
Kernel: Tried with latest Ubuntu kernel 5.4.0-xxx and kernel.org kernels 5.4.182 and 5.10.103
The RAK card does not even seem to power up (LED is off). We have tried with two cards so it does not seem to be a faulty card issue.
I have noticed most of people are using RAK cards on Pis. Is x86 PC even supposed to work? The cards are advertised as mPCI-e and:
It can be used in any embedded platform offering a free mini-PCIe slot with SPI/USB connection.
We have tried to follow RAK2247 Quick Start Guide | RAKwireless Documentation Center, but we do not know how to do this:
If you want to connect the RAK2247 mPCIe board to the Linux PC directly, make sure to have the PERST# signal (Pin 22) pulled down.
Any help is appreciated.
