Could you please tell me if there is an error in the table under "Memory Layout" here:
https://infocenter.nordicsemi.com/topic/sdk_nrf5_v16.0.0/lib_bootloader.html
In the column "Memory range nRF52833 (S140 v7.0.x)", the Application area start address is given as 0x0002 6000.
I have been using 0x27000. Trying 0x26000 doesn't seem to work.
