Blinky on nRF52 DEV via Black Magic Probe: SIGSEGV in os_pkg_init

It's very likely that I'm doing something wrong so I'm reaching out for help. All I want to do right now is to get Blinky working on an nRF52. I followed the tutorial and built the boot loader and blinky. I then created an image so the boot loader would be happy about the magic number. I used

Hi Will, hi Chris, thanks for your hints. I thought it would be less risky only to reduce the counts and not the size of the buffers. I tweaked a bit with the values of MSYS_1 and found this is working for my current app: MSYS_1_BLOCK_COUNT: 10 # was 12 MSYS_1_BLOCK_SIZE: 180 # was

Re: What are the best config settings to reduce ram usage, so that an app runs in 16 kb with least impact on functionality?

Alfred: Another thing with the nimble stack. The mbuf block size of 292, which Chris shows reduced to 200, is much larger than it needs to be. I am not sure what the smallest size actually is, but you can set it to 100 bytes and it should work. This can get you more buffers and/or reduce your

What are the best config settings to reduce ram usage, so that an app runs in 16 kb with least impact on functionality?

Hello all, I’m experimenting with mynewt for several weeks now and I’m especially impressed by the statistics, logging and image update functionality. I’m having problems with getting all the statistics using newtmgr via BLE. I took bleprph as base, added ADC and enabled several stats, logs and
