Region name in nRF Connect Programmer v3.3.2

[Joe]

When I move the mouse pointer over the area, I will see the Region name "Bootloader", "Application", "SoftDevice", etc, along with the addresses and size. Where are these names get set? Is it part of the hex file? Sometimes when I build my own hex files, I only see the name "Application" for all area. May be I am missing something in the process.

Thanks.

Hi

All of this is open source, and you can see the algorithm/logic on our GitHub. 

A short recap of how the various regions are detected:

• Region with address from 0x0 is either MBR or Application
• The SoftDevice region is detected by a "magic" number
• The bootloader region has a fixed address according to what Development kit is used
• Based on the regions mentioned above, we have some assumptions for application regions

Best regards,

Simon

Hi,

I have rebuilt the dfu secure bootloader under ble_s132_pca10040 for SDK 15.0, 15.3 and 16.0. When I drag the hex file for 15.0 and 16.0 to the File memory layout window in the Programmer, the region name will display as "Bootloader". When I drag the hex file for 15.3, it will show up as "Application". Maybe there is some signature missing in the 15.3?
