I've seen some issues when using USB0 as host and USB1 as device at the same time
USB0 (host) is using OHCI driver
USB1 (device) is using kUSB_ControllerIp3516Hs0, it seems to work when used alone (?)
The main issue seems to be that both tries to use the shared ram at the same address
so the setup of USB1 breaks usb0
For usb0 : FSL_FEATURE_USBFSH_USB_RAM_BASE_ADDRESS (0x40100000)
For usb1: FSL_FEATURE_USBHSD_USB_RAM_BASE_ADDRESS 0x40100000)
It is probably a misconfiguration/mistunderstanding from my part,.
Any pointers would be appreciated
Thank you in advance
I have noticed the exact same problem which leads to memory corruption of the OHCI USB stack. I found a race condition in the device driver when the hardware received a SETUP token while USB_DeviceLpc3511IpSetDefaultState() is in progress. The HW store the setup packet (8 bytes) at 0x40100000. You can find more details here:
My solution is to modify the device driver to remove the race condition. it is posted in my first post in a zip file.
This is for LPC54xxx family, but your MCU USB software interface (UM11126's figure 161) is identical to mine, so the solution should work.
