OTA/DFU bootloader memory map increasing size in pca10056_s140_ble

[Dominik Eugster]

Hi

I added some code to get the PA/LNA driver enabled in the DFU bootloader on my board accordig to this post:

https://devzone.nordicsemi.com/f/nordic-q-a/50687/pa-lna-in-bootloader

Now I added some IO and ADC function which I need and the size in Segger Embedded Studio was too big.

So I changed the memory size of the bootloader. Increasing te size was not working. So I changed the start-address to the increased size, is this the correct way?

old values:

FLASH_START = 0xF8000

FLAH_SIZE = 0x6000

The compiler is ok, please check.

Hi Dominik, 

Yes what you are doing is correct. There are a bootloader setting page and MBR info page at the end of the flash. You can have a look here: https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/lib_bootloader.html?cp=8_1_3_5_0_7#lib_bootloader_memory

So you need to move the start address down 0x2000 bytes and then increase the size 0x2000 bytes.
