Hello -
I'm experimenting with elevating the priority of group 2: UART0 and T2 above everything because I need a very fast response to a received message in the UART by DMA. I am also using the BLE radio.
My question is this: When I set group 2 to the highest priority and the RF/DMA to one lower, the CC2540 locks up as soon as I start up BLE (stops responding to the UART ISR and if I paused the debugger it is all 0xFF in the registers). I am guessing this is because Timer 2 (MAC timer) and the RF radio are used in some way that the RF radio has to be higher, but I'd like to get a more official answer instead of my guess if possible.
I am changing the priority by:
IP0 = 0x05; // UART0 now has priority over RF/DMA
IP1 = 0x14;
Thanks in advance!
