RM520N connection

[megaumnick]

#Hi everyone,
I upgraded from OpenWrt 24.10.3 r28872-daca7c049b / LuCI openwrt-24.10 branch 25.264.713013974d8a to ImmortalWrt 24.10.3 r33451-5531f6bc76a3 / LuCI openwrt-24.10 branch 25.265.361885ff7e61 using update_script.sh.
There are two issues:
First — upon SSH login, an ASCII "BananaWRT" banner appears, and there’s no command prompt until I press Ctrl+C.
Second — the RM520N-GL modem is not detected.
While the first issue is not critical, how can I fix the second one?

Can you open a issue for this? i will give a look soon.

Second — the RM520N-GL modem is not detected.

Which version do you have? Could you attach a photo of the module? There are two versions, one PCIe only (not supported by BPI R3 Mini) and the other USB (That's supported).

Hey, I've already tried out a bunch of firmwares and totally messed up the NAND boot loader. As soon as I unbrick my BPI R3 mini, I'll get BananaWRT up and running and open up an issue. What info do I need to gather?

The modem version is RM520N GL-AA—I know about its quirks. It's the one with the Evaluation Board.

I have a feeling you're experiencing the same issue as I am with the FM160 — it's not being detected (#75).

I've reported it to them here: https://forum.banana-pi.org/t/banana-pi-r3-mini-issues/23673

This is a known issue with the R3 mini. There is a workaround in the form of a bash script that checks the USB upon boot: if it does not detect the modem, it reboots after 60 seconds; if it does, it sends an AT command.
In my experience, this script has only triggered a couple of times, no more. It is necessary to create a separate image for working with this modem, as it has an unusual power-on sequence.
