Hi Fabian, yes, it does work. Thanks for finding out. But, having thought more about this I have come to a conclusion. Parsing of returned strings from a 3rd party device is not a good solution. Yes, you may keep the exact same formatting and license naming - but the principle of having to rely on something that you have no control of should be avoided if possible. Let me fill you in with some additional details. We have a NRF52840 device and we can program this using NRF eval boards (comes with…

Hi, I need to be able to check whether a programming device has J-FLASH license installed, so that I can use the erasechip command in J-FLASH. And I need to do this in command line. I can start j-link and then type 'license show' and it will give me a list, which I could parse if I could get as a return string. But I can't see how you run this in the command line and the documentation does not mention anything about this. I can also also see licenses using JLinkLicenseManager.exe but that progra…

Does the chip gets reset or does it just continue in its current state? Kind regards, Christian

I never said that it was a bug. It is just not working in the most optimal way.

Looking at the datasheet an eraseall should complete within 169ms, so j-flash must be doing it right (via the eraseall command) whereas jlink probably erase page-by-page. Is that correct?

Hi, I have a NRF52840. If I do a chip erase using j-link it takes app. 15s, but if I do a chip erase with j-flash then it only takes 0.7s! Can anyone explain the difference? I don't understand whythere is a factor 21 in difference of speed. For jflash I have used both the command line the GUI. Both complete in the same time and a subsequent blank check report the chip as being blank Kind regards, Christian

Hi, This is a very old error that keeps on recurring for some reason. JFlash wants to store an .ini file in its installation directory but is unable to do so due to lack of access rights. Have encountered it in the 6.30 release. Please do not post answers about running JFlash with administrator rights, or running JFlash from a different directory. These are not viable solutions as you cannot count on being able to do either. For example, it is normal to have such restrictions in a production env…
