Hi guys,
I compiled the openbootloader example and when I try to run it on NRF52840, It gives segmentation fault:
(gdb) load nrf52840_xxaa_debug.hex
Loading section .sec1, size 0xe1f0 lma 0xe0000
Loading section .sec2, size 0x8 lma 0x10001014
Start address 0xe02b4, load size 57848
Transfer rate: 19 KB/sec, 948 bytes/write.
(gdb) run
The program being debugged has been started already.
Start it from the beginning? (y or n) y
Starting program:
warning: No executable has been specified and target does not support
determining executable automatically. Try using the "file" command.
Program received signal SIGSEGV, Segmentation fault.
0x00000000 in ?? ()
but If i use the existing provided hex file it works fine
(gdb) load open_bootloader_usb_mbr_pca10059_debug.hex
Loading section .sec1, size 0xa18 lma 0x0
Loading section .sec2, size 0x10000 lma 0xe0000
Loading section .sec3, size 0x10c lma 0xf0000
Loading section .sec4, size 0x8 lma 0x10001014

^C

why is the one that i compiled failing? I havent made any changes to the files.
your help would be appreciated
Update 1: I checked with secure USB bootloader, secure BLE bootloader, the production version of these as well and same thing happens.
