  • Unfortunatelly it doesn't solve my problem. Bootloader and my app works fine on NRF51-DK. Now I'm porting it to QFAA chip with 16KB of RAM. In my case was required to set IRAM1 0x200025F0 : 0x1A10. Bootloader works in QFAA chip, I am able to send new firmware over nrfConnect but new app doesn't start. After firmware upgrade it's again in bootloader. Bootloader logs attached. Another problem that I see logs only when #define NRF_LOG_DEFERRED 0. If I set #define NRF_LOG_DEFERRED 1 logs are silent boot_log.txt

  • I think no need to change application start address. Because it's always located above softdevice. For bootloader (In my opinion) we can set start address as small as possible. When I start experiments I set bootloacer start addres 0x3ACO00 and size 0x5000. When I enable loggin this size was insuficcent and I change start address to 0x37C00 and size 0x8000
