OTG port not working on 5.3.0-rc8 kernel #26

Hello again @avafinger

Can you please confirm if the USB OTG port is working on latest released kernel? I was previously using a bluetooth 4.0 dongle but after upgrading the kernel it doesn't show anymore in lsusb or whatsoever.

All i get is the following output using lsusb:

Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 009 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Hi @thiagobucca

Can you please tell which kernel version was working? I have not changed OTG configuration.

&usb_otg {
    dr_mode = "otg";
    status = "okay";
};

BTW, why are you using a bluetooth 4.0 dongle, the BT from the board isn't working for you? You can always revert to the previous kernel by doing this:


check before reboot:

ls -la lrwxrwxrwx 1 root root 32 Set 3 09:14 bpi-m2-zero.dtb -> bpi-m2-zero-v4.dtb_5.3.0-rc7-m2z lrwxrwxrwx 1 root root 20 Set 3 09:14 zImage -> zImage_5.3.0-rc7-m2z



* reboot
`sync && sudo reboot`

Maybe you can symlink to the working kernel and grab dmesg **before** and **after** you attach the usb dongle, might be related to kernel config.

I just found out that my problem has nothing to do with the image, i'm sorry. I just checked my board and the OTG port has a loose connector, after resoldering it worked fine.

I use a bluetooth adapter because onboard bluetooth cannot detect my miflora BLE sensors which i'm using to monitor my plants, not the best option but it works.

Anyway, thanks for the attention and sorry again for the false alarm.

Don't know much about miflora BLE sensors, but BT on bpi m2z is 4.1. You should see something when you do a :

sudo hcitool lescan

Maybe some kernel config missing, but CONFIG_BT_LE=y is there.

Actually i tried to use onboard BT but following the instructions on the main page, my board never go past the following line:

writing 01 03 0c 00

i noticed i didn't have the file named bcm43438a1.hcd on /lib/firmware/ap6212 path so i downloaded it from SINOVOIP's github, but i really don't know if this is the problem.

@thiagobucca You can test a fix for the BT and HDMI, please refer to: https://github.com/avafinger/bananapi-zero-ubuntu-base-minimal/issues/27#issuecomment-534787251
