Data transfer between external controller to IMX8QM-MEK through SPI or UART

[vinothkumars]

Hi All,

I have a Companion microcontroller which is already flashed with RTOS and this Controller continuosly transfer the data over SPI or UART.

I needs to get the data to the linux (IMX8QM A9 Processor). Is there any way to get to it. or it should be simlar like normal UART or SPI interface
