NRF52832 Dev Kit / J-link OB / Keil not working

[jtf]

I have been working with an older version of the development kit for years without any problems. However, these new kits are giving me a lot of trouble. I bought several of them, and they all come with the new J-Link OB. I installed J-Link v7.86, and the command line tools seem to be working now, except that I always have to run "nrfjprog --recover" first.

nRF Studio no longer recognizes the programmer, but the biggest issue is that although Keil does flash the board, it still doesn't work. I have tried erasing the chip, flashing the softdevice with nrfjprog, and then flashing the program from Keil, but it still does not work. 

(Are the old models still available for purchase somewhere???)

Hi,

If you are looking to by a specific version of some our products the I suggest you contact sales team. They should be able to help you find what is available and where, but we generally do not have multiple versions of one product in production at the same time, only the latest version is in production (unless the product is end of life). So contacting some suppliers/resellers might also be a good option. ask if they have any stock of a the version you are looking for.  

I want to note that  nRF go Studio is obsolete and intended to be used with only legacy products. So updating to nRF connect for Desktop is recommended. There you have the new nRF programmer app that supports the new J-Link OB. 

The new kits have readback protection so that is why you need the --recover as for Keil, not sure that it is updated to support the J-Link OB that is used on the new DK's so the experience there is probably hit or miss. And as we no longer support Keil its not much we can do.
