I got 2 BPI-M2-Zero boards, both with the same problem. I can’t get a keyboard to work. Lights never even flash, no capslock etc. No power to the mouse either. Both boards boot fine but I can’t go anywhere from there. I’ve tried 3 different keyboards. All of which work on my raspberry pi zero w. I’ve tried the latest armbians: Armbian_23.5.2_Bananapim2zero_jammy_current_6.1.30.img Armbian_23.5.2_Bananapim2zero_bookworm_current_6.1.30.img
Did I just get two bad boards?
Thanks!
Hi, Hi Mickey,
No your boards are not bad. I had the same problem with the same image versions. Apperently USB is not working of this armbian version. I ended up using the UBUNTU variant as seen on the wiki-pages: https://wiki.banana-pi.org/Banana_Pi_BPI-M2_ZERO#Armbian

armbian disable microusb host mode since 5.17, you can apply this patch m2zero_armbian_6.x_enable_otg_host.patch (5.0 KB) and build armbian image by yourself to enable otg host mode.
Hi August,
Thank you, that clears some questions

I’m going to reply just in case someone else hits this.The bana-pi’s usb is kind of sensitive. I had a micro usb to usb-C adaptor and a usb-C to standard to plug in the keyboard. (aka 2 daisy-chained adaptors) This setup worked on my pc and the raspberry pi zero w but NOT the banana-pi. I think it’s not as fault tolerant. I even did a self-made adaptor that worked everywhere but the banana-pi. It’s only 6$ for two of the single adaptors so if anyone is having trouble, it’s well worth it.
Can you please explain how to patch? I’m a newbie for these kinds of things
Sorry i just dont understand so the BP m2 zero worked only with the adapters you linked and you didnt have to change OS or anything else?? Thanks in advance.
Yes, exactly. I had other adaptors that worked with the R-pie but not the M2-zero. I was shocked when the one I listed worked. I used the two mainline distros I listed above and they both worked.
another simple way is disable load g_serial module
