Part Number:DRA756
Tool/software: Linux
Hello!
HW : custom VAYU board.
I am in the process of porting SDK from GLSDK 7.04 to Processor-SDK 3.02.
Target board is based on DRA7X_EVM(VAYU 703761-1031), there is no much differences.
I have no problem with GLSKD 7.04.
But after applying Processor-SDK 3.02, USB1 device mode is not working.
When "ums 0 mmc1" command is used at u-boot, gadget driver and stoage of ther target is found on the host linux PC.
After kernel loading, I can use usb1 as device mode.
But I couldn't use device USB1 port without u-boot command.
When I tested with previous version kernel config and device tree(based on GLSDK 7.04 ) with same u-boot, it was OK.
(I tested host mode by changing device tree, it worked perfectly in host mode.)
I think definitely kernel config or device tree is something wrong.
I have checked clock, regulator supply etc.
But I cann't figure out what's wrong.
Is there any other suggestions or tips?
Thank you
