Below is the project showing reception and transmission of character on UART using RX interrupt on CM4 core.
It is working fine when I am using code with CM4 core, but when same code I am using with CM0+ core it won't work.
I did some research and found that UART interrupts are not linked with CM0+ core.
I just want to confirm whether UART interrupt is generated with core CM0+ and if yes, how to write code for the same.
To assign the interrupt to the CM0+ core, open the Design Wide Resources tree in you Workspace Explorer window. Open the Interrupts tab and enable the UART interrupt on the CM0+ core. Also disable the interrupt for the CM4 core.
Code should now work.
