during testing a RM500U-CN module in a prototype board I accidentally switched it into PCIe EP mode (AT+QCFG=“pcie/mode”,0). How can I switch it back to PCIe RP mode without being able to connect it to a PCIe bus directly? My development board does not support this.
Is there a way to factory reset it without having software access to it?
Dear @vaenner.net
Did you install the USB driver on your side?
The latest PCIe driver is Quectel_Linux_PCIE_MHI_Driver_V1.3.6 , I will sent it to you via Message, please check.
The USB driver is built into the kernel (Debian 6.1.52-1). I was able to connect to the ttyUSB2 device before I accidentally switched to PCIe mode. Now the modem is not found any more by this built in driver.
