Writing firmware in SES issues

[masterLee]

Dear all,

I use Segger embedded studio to upload my firmware to my nRF52840 custom board. When I do it with build and run button everything works as expected but when I do it from Target > Download File > Download .elf file, nothing seems to work. What am I doing wrong?

Thanks

Hello,

Does it work if you click this button instead: 

? Note that the "Download .elf" button will only program the application FW. It will not include other files such as the Softdevice.

Hi Vidar, 

I tried the blinky example (blank) to make things more simple. Yes the way you mention works  but when I try to do it with Download file > ...  it doesn't work...

My core issue here is the following.
I want to send to a colleague the .bin file of my code so that he can perform some tests he wants and when I place the .bin file with "Download File > Download Binary File" to check that the code is uploaded to the chip without issues it did not work. So I thought to do the same thing with the .elf file and it didn't work either.

You can use it to merge bin files that don't have gaps. objcopy is included with the GCC toolchain which can be downloaded at: https://developer.arm.com/Tools%20and%20Software/GNU%20Toolchain

I am looking for an easy solution that will not take time and objCopy seems that is not easy to handle

do you know if hex2bin could do the job?
hex2bin.sourceforge.net/

I think I did it with JFlash

[Vidar Berg]

Yes, that might work. I haven't tried it myself.

Yes it worked ! :)
