Hello all:
I recently add a support for customize am3358 board using the branch
processor-sdk-linux-03.00.00 from Ti git. But I meet a problem with musb
at the peripheral mode.
Then you are going to have to get support from TI for this, nothing we
can do here about random vendor kernel trees, sorry.

If you can use the 4.7 tree, or better yet, the 4.8-rc tree, then we
I have tried the 4.8-rc1, I meet the same problem.
What problem is that exactly?
Sorry, the USB1 can't work at high speed gadget mode and have DMA problem.
musb-hdrc musb-hdrc.0.auto: Failed to request rx1.
musb-hdrc musb-hdrc.0.auto: musb_init_controller failed with status -517


I have enabled the CONFIG_OMAP_USB2, I don't find at ti's kernel.
I don't understand, is that your hardware you are using?

thanks,
