Hello, I’m very interrested in the i.mx 7 SOM module and the cortex-m4 co-processor feature.
I would like to know if that is possible to use a UART to perform RS485 on the cortex-m4 with FreeRTOS.
I have to support an awkward protocol which required polling multiples RS485 sensors with near (hard) real-time precision at 100 HZ. Also the protocol is using 9bits UART. (which is not very common)
I was thinking to perform the RS485 sensors scanning with FreeRTOS on the cortex-m4 and then send the results to the Cortex-A7 processor via OpenAMP/remoteproc feature once per second or so…
Do you think I can perform this task with the Colibris i.mx7 SOM and the Aster Carrier Board ?
Thanks for your comments.
