IMX7D USB2.0HOST access from FreeRTOS on M4

[andreas_vorderl]

Hi,

I have waste so much time in search but without success and I hope you can help me by answering my question about USBHost access from FreeRTOS on Cortex-M4.

Is it possible to access or connect a USBtoSerial Adapter to the FreeRTOS on Cortex-M4?
Is this possible in principial? If yes does there exist any driver for the interface?

The exact processor: MCIMX7D5EVM10SC

Thanks in advance for your reply.

i.MX7D Reference Manual, configure properly RDC.

FreeRTOS USB examples can be found for i.MX6UL SDK (i.MX7 has not them)
