Please describe your issue below:
Quectel RM520 with R03 firmware does not work in PCIE mode.
Dmesg shows the message below and the /dev/mhi_DUN etc devices are not created.
The same config works on older Quectel R01 firmware.
Quectel say the R03 works in PCIE mode on other boards.
Is there anything I can do to change the driver config to work around this error ?
Hi @numbqq I hope you had a good {short} holiday!.
I installed the 1.7.1-240930 image - exactly the same results - only /dev/mhi_BHI is present none of the other mhi_* devices. Also the same message in dmesg.
I can give you ssh access to a VIM4 with the RM520 if that helps - or I can DM you the detailed comments from Quectel.
@numbqq Have you upgraded to the latest firmware on the RM500 ? It used to work on the older firmware on the RM520 then stopped working when I upgraded to get the e-sim functionality.
(backstory:
On an older module with a damaged antenna connector I ran
QFirehose -f /mnt/sdb1/firmware
to do the upgrade with the correct firmware from Quectel.
I assumed I’d bricked it because the interfaces didn’t come up, and bought a new one.
Turns out that the upgrade was fine but it doesn’t get on with your pcie kernel driver…)
