bootloader_secure_ble space

[Roger huang]

I want to add a function to bootloader_secure_ble, to drive a lora chip, I can upload some user code by this code. but I don't know how many space can be used.

do you have a doc to describe the layout of the bootloader ,SD and app?

thanks for support

Hi Roger, 

You can increase the bootloader size if you need to implement your code in the bootloader. Please have a look at the layout here: https://infocenter.nordicsemi.com/topic/sdk_nrf5_v16.0.0/lib_bootloader.html?cp=6_1_3_5_0_7#lib_bootloader_memory

What you need to do is to move the bootloader start address down in flash location, giving the bootloader more space. To do that you need to change the IROM1 configuration (or the FLASH_START if you use SES)

Thanks, it's what I wanted.
