An error occurs when generating an output hex file using the mergehex function

[ysepulveda]

I'm attempting to merge 3 HEX files into one using the Merghex command. The "BinaryImage access" error appears, see the screenshot below. 

I've tried this several times with different files names etc and the error keeps showing up. I have version 10.17.3

Hi Yerko, 

If you only merge the bootloader and the softdevice, do you see any issue ? 
I suspect that the image "BackBea...hex" has some overlapping flash area with either the softdevice or the bootloader that can cause the issue. 

Could you try to test with other application image ? For example blinky s132 example ?
