Subject: Aw: Re:  [PATCH 0/2] Add MUSB for MT7623
Date: Wed, 4 Aug 2021 13:33:16 +0200	[thread overview]
Message-ID: <trinity-62b8c96c-2408-46d3-9690-e78af2f0c250-1628076795963@3c-app-gmx-bap67> (raw)

Hi,

another strange thing is, after some bootups (i boot kernel from tftp, but also on full power cycle),
musb-driver maps musb-hdrc.4.auto instead of #1

root@bpi-r2:~# dmesg | grep musb
[    5.502914] musb-hdrc musb-hdrc.4.auto: MUSB HDRC host driver
[    5.508782] musb-hdrc musb-hdrc.4.auto: new USB bus registered, assigned bus number 5

and then nothing works (no roleswitch, no power which does not work with pinctl / without regulator).
It's hard to test if things working before, do no more work if device is named differently.

maybe Min Guo can help here?

after bootup mode is b_idle in my case (currently do not change if i connect otg cable)

root@bpi-r2:~# cat /sys/devices/platform/11200000.usb/musb-hdrc.4.auto/mode
b_idle

regards Frank
