Is core1 necessary ? #6

You use Core1, but why ? Code : multicore_launch_core1(core1_main); Is Core0 more sensitive to interrupts or others hardware interactions ? Thanks for your expertise.

Both core are needed, on core1 i run the bus emulation, that had a timing aligned with console and can't stop never. On core 0 run all other stuff.

I understand now the uncommented line : multicore_launch_core1(core1_main); Maybe, i can add comment : // Core1 run the unique function "core1_main()"

then, in function "void __not_in_flash_func(core1_main())", you must specify this function : multicore_lockout_victim_init(); Maybe, i can add comment : // Core1 is obliged to do a pause in knew state by Core0.

Is Core0 more sensitive to interrupts or others hardware interactions than Core1 ?
