I want to update the bootloader inside nRF51422 using iPhone. Updating applications hasn't been any problem.
Following the same procedure but I cannot convert bootloader.axf to bootloader.bin
This is the command I am using c:\keil_v5\arm\armcc\bin\fromelf.exe --bin --output bootloader.bin bootloader.axf
This is the file bootloader.axf
The result is only a folder bootloader.bin, which I guess is for error message, but cannot read.
