g_multi not working Nanopi neo air Mainline kernel

[seaskyways]

Hello everyone,

 

I am using Nanopi air and I wish to have ethernet and mass storage simultaneously. I went through numerous problems but now I have OTG working. 

If i try modprobe with g_serial, g_ether, or g_mass_storage, each works individually. 

Even g_cdc ( ethernet + serial ) and g_acm_ms ( mass storage + ethernet ) work.

when I try to run : modprobe g_multi file=/sdcard.img 

I get the following:

[  290.720691] g_multi gadget: unable to autoconfigure all endpoints
[  290.880936] g_multi musb-hdrc.1.auto: failed to start g_multi: -524

 

Please help
