Hello all,
I would like to have some advice or hints on USB Driver under U-boot.
I am porting uboot-socfpga to latest version of custom board, where USB PHY and connection are exactly same as previous.
With Same Cyclone V device.
I am using https://github.com/altera-opensource/u-boot-socfpga
rel_socfpga_v2013.01.01_14.09.02
On previous board if works very good.
But on the new one there is some problem
When I tried branch v2017.09 on new board, USB again works as it should be.
I change only bootloader and USB is working.
I need to stay on uboot 2013 and make USB working again. (a lot of new problems on new uboot)
Problem is that in Uboot 2013 after it detect USB Hub it reads
Port 1 Status 400 Change 9 - e.g. no device connected.

Port 1 Status 400 Change 9
port 1 connection change
But in Uboot 2017 after same sequence it reads
Port 1 Status 511 Change 1 (same as on Uboot 2013 on the previous board)
usb_control_msg: request: 0x0, requesttype: 0xA3, value 0x0 index 0x1 length 0x4
Port 1 Status 511 Change 1
devnum=1 port=1: USB dev found
Do you have any ideas why Uboot 2017 works OK but Uboot 2013 is causing the same USB Request to read different USB status?
Thank for any information.
BR,
