If you tried the same script on your computer, and it works fine. With the same JLink version and debugger. And you also tried Michael's suggestion above to include a 'r' and 'h' before erasing, I'm not really sure what is wrong. You can ask in the Segger forum if they have any ideas.

What happens if you open JLinkExe without any parameters, and do the connect, erase, etc. manually? Does it still fail on the erase? What if you do a full erase of the chip on your computer first and then try to just load the file on the RPi without running the erase command first? Is it still failing?

It works fine with my computer ! I am using "JLink_Linux_V670a_arm".

Your script above does not include the commands r and h before the erase.

Have you remembered to include these elsewhere in your process. The chip must be halted before you try to erase and flash it.

I assume this is for an automated programmer and sending a long command (such as the one used in commanderscript implimentations) but there much easier ways to do this. I just call something like:

./full52flash

You need to make JLinkExe globally callable on the RPi and then just create a .sh with:

#!/bin/bash
JLinkExe >> EOF
* all the manual JLinkExe commands you use, new line for each *
EOF

then quickly chmod the .sh so it's known to the OS as an executable and your done

Is this only on the RPi or do you see the same thing on your computer? Which JLink type/version are you using?
