NRF5340 RTT on both cores simultaneously

[rookie]

Hi,

I would like to set up RTT on both net and app cores, but I haven't been able to get both running simultaneously. I'm wondering if this is even possible, and if so then what would be a good reference point to do so. I am able to run RTT on each core separately, but not together, perhaps I'm missing some crucial step

Hi, 

It's not possible to get RTT on net and app cores simultaneously because the debug probe can only host one RTT session at a time.

One workaround is to put one RTT session in shared memory so that both cores can use this one. Each core can then use a separate channel. This may require synchronization between the cores so you don't get data corruption.
