No BLE possible with CONFIG_NO_OPTIMIZATIONS=y for a nRF5340 project

[Stefan Schmidt]

Dear Support-Team,

 I have checked that now back and forth: When I add 

CONFIG_NO_OPTIMIZATIONS=y
CONFIG_MAIN_STACK_SIZE=8192
CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=8192

in my prj.conf and build with sysbuild, flashing the merged_CPUNET.hex and merged.hex to the application core, the application hangs in bt_init().

When I remove these settings and build and flash everything again, the application starts.

Do you have an explanation for this?

Best regards

Stefan

The  merged_CPUNET.hex file must be flashed onto the network core. But "west flash" should know to do that.

A hangup in bt_init usually means the net core is not properly flashed.
