Hi Fabio,
Just have a question, the tcpci driver is not supported, so how
do you manage to make SDP work?
I understand that the tcpci driver is required when a USB role switch is needed.
I am only using the usbotg1 as a peripheral.
ok, got it.
Here are the logs:

One issue that I observed and haven't had a chance to debug yet is that
running 'ums 0 mmc 1' works only when issued for the first time.
If I interrupt with CRLC+C and then launch 'ums 0 mmc 1' again, it
does not work.
This is unrelated to SDP and happens when I boot from SD card as well.
If you have any ideas, please let me know.
I am not sure, the master branch has this issue? Any specific config
option required?
Thanks,
Peng.
