Hi,
I want to use iMX8M Mini, UART 3 for M4 as a Bluetooth interface. M4 will be running with Zephyr OS.
On the EVK board UART3 is available from the header and the pin details for UART 3
TXD - Pin 8
RXD - Pin 10
In Zephyr (boards/arm/mimx8mm_evk/mimx8mm_evk.dts) I have modified the device tree like below.
zephyr,bt-uart = &uart3;
&uart3 {
status = "okay";
current-speed = <115200>;
};
Do I need to do any other changes? What about RDC domain settings?
Does M4 needs to be in RDC domain 1 and UART3 needs to be assigned to domain 1 ? Where this changes are needed? Is it in Zephyr or in the u-boot?
Any help is appreciated.
Thanks in advance,
Best regards,
Pradeep
