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
@Niebel-TQ @igorpadykov I'm also facing same problem with U-boot hangs on hsic PORTSC register.
Have you succeed and do you have any updates?
Hi Markus
hanging may be due to clocks gating in CCM_CCGRn registers,
one can look at linux hsic implementation
linux-2.6-imx.git - Freescale i.MX Linux Tree
and post on uboot mail list
Best regards
igor
