USB OTG with rocko and kernel 4.9 RT
Added by V J about 5 years ago
Hi
I am struggling to get USB OTG up and running using the rocko branch with kernel 4.9 RT (ref. https://support.criticallink.com/redmine/boards/45/topics/4963?r=5812#message-5812)
I have connected a USB hard disk (mass storage) to the USB OTG port but the USB device is not recognized. I also notice that D406 on the evaluation board is not on.
USB related messages in dmesg (I have enabled some debug options):

USB OTG is working when using the original SD card (kernel 3.16) that came with the evaluation board, and LED D406 is on. USB related messages in dmesg for this version:

USB OTG was also working on kernel version 4.12 which I have used earlier.
I have tried with various kernel configurations, but have not managed to get it to work.
Is this supposed to work “out of the box” for the rocko branch with kernel 4.9?
Are you aware of any changes in kernel 4.9 compared to earlier versions which affects the USB OTG?

RE: USB OTG with rocko and kernel 4.9 RT - Added by Daniel Vincelette about 5 years ago
Hello,
There is a patch missing from our 4.9 RT branch, sorry this was missed when we did the RT port. I'm working on getting that merged in now.
In order to get USB OTG to work with the MitySOM-5CSX you need the following patch: https://support.criticallink.com/gitweb/?p=linux-socfpga.git;a=blobdiff;f=drivers/usb/dwc2/platform.c;h=7f2cdc926f287b161d68c2e07b415a4018e9d618;hp=2dfb140567c06a01c6ce74346f425070eb6933f0;hb=7ee4a5102924e434458f1e93e986b9fc1f021a65;hpb=7d052214ad7f2ae552649bf7e1acec667c9667b8
This patch adds a new config that will configure the USB PHY to enable VBUS.
I'll update once I've tested and pushed it, should be by the end of the day.

Hello,
Just to update you, I've applied the patch I mentioned but unluckily VBUS still doesn't turn on. This will unluckily take a few more days in order to get to work it seems.
We will update this redmine once we have USB working with the 4.9 RT kernel. My apologizes for the delay.

Hi
I have tried the patch here, but got the same result as you: no VBUS.
Thank you for working on this issue.

RE: USB OTG with rocko and kernel 4.9 RT - Added by Daniel Vincelette about 5 years ago
Hello,
We've found the other patch that was needed: https://support.criticallink.com/gitweb/?p=linux-socfpga.git;a=commit;h=a5ae1d10efe50e0a80a4cd401992624d1218399a. With both patches USB will enumerate correctly and works as expected.
I've pushed both the patches to https://support.criticallink.com/gitweb/?p=linux-socfpga.git;a=shortlog;h=refs/heads/socfpga-4.9.76-ltsi-rt
Thank you for reporting this issue and please let us know if you have any further questions.
Kind Regards,
Dan
RE: USB OTG with rocko and kernel 4.9 RT - Added by V J almost 5 years ago
Thank you for the update. I now have a working USB OTG.
I needed to build the kernel with option CONFIG_LBDAF to be able to mount my SSD.
(Ref. mount message: "EXT4-fs (sda1): Filesystem with huge files cannot be mounted RDWR without CONFIG_LBDAF").
