Hello everybody !!!
I was assigned to implement Host USB compliance in board imx6q, but this is the first time. So I have a trouble, look forward to help.
This is electrical circuit :
On imx6q board, I used memtool to change register to enter Test mode. I had followed in 5367 page of imx6q reference manual documentation(Port Test Modes -Host Operational Model). But I had failed.
1. memtool -32 USBOH3.UH1_USBCMD.ASE=0
memtool -32 USBOH3.UH1_USBCMD.PSE=0
2. memtool -32 USBOH3.UH1_PORTSC1.SUSP=1
3. memtool -32 USBOH3.UH1_USBCMD.RS=0
wait for read memtool -32 USBOH3.UH1_USBSTS.HCH to get 1
4. memtool -32 USBOH3.UH1_PORTSC1.PTC=1 (TEST J)
here I saw Oscilloscope and the wave completely unchanged.
Am I wrong somewhere or forgot about it?
Hope everybody help please !!! Thank you.
