If it was set to 0, that is probably not the issue, no. But can you try 32768, just to completely rule it out?

Do you get the twim error if you do not comment in the magnetometer, but enable log?

Can you use a debugger to find out exactly which function causes the twim error and the buffer overflow?

I assume the image size is not something you can change, but if it is, can you try reducing it significantly?

If none of that works, can you show me the code for the sensor_setup and enable_sensor functions?

Can you try increasing CONFIG_HEAP_MEM_POOL_SIZE?

If you are using our DK or our board files, can you try using different pins for i2c2? Not pin 32 or 33.

You are getting an "address not acknowledged" error from nrfx_twim.

Can I see the overlay and prj.conf files?

Hi,

Can you show me the log when this error occurs? Were there any warnings when you compiled the project?
