Hi
I am working on a BLE repeater which is central and peripheral application. which will scan and connecting with sensor device , and advertising for phone connection.
but the rom size is too large now. I cannot adding OTA function. there is my application memory report, it take around 254 kB. if I split the ROM area for 2 image. my application oversize.
In partition planning, I already reduce the MCUBoot area to 28kB , and setting page reduced to 8kB,
and following is my config setting

does any setting can help for reduce the size for OTA function.
but there are some limitation ,
1. we cannot setting optimization
2. we are using nRF52833 ,only 512kB flash area
3. we cannot add extern flash IC for OTA.
Do any idea to reduce the rom size or increase the image size.
Thank a lot
