Hello, I try to use the third USB controller on a custom board. When writng the PORTSC register system stalls.

 

What we have done so far:

 

- use U-Boot rel_imx_4.1.15_1.2.0_ga

- extend ehci.mx to support 3rd controller witch HSIC

- on chip regulator 1P0D and HSIC_1P2 are enabled

- enable_usboh3_clk is called

 

any hints?

 

Thanks

 

Markus
