I am a newbie in nrF52832. I have been carrying some experiments using the Nrf51 and so far they are going so well. However, I came across some few E104-BT5052 samples originating from the eByte http://ebyte.com/product-view-news.html?id=956 and I would like to do a reprograming of it.
I tried flashing them for the first time and the outcome was an error that indicated that they were protected and the only thing that needed to be done was an eraseall and that could lead to unprotecting them. I did that and that enabled me to load all my binaries. To my surprise, after the binary loading it was not possible to record the loading. I did too many research and this led me to recovering them using the procedure listed below:
1 Execute "nrfjprog -f nrf52 --recover" in a loop with a script
2 Remove GND and VCC
3 Pull-UP Reset PIN
4 Connect GND
5 Connect VCC
With the above procedure there was the possibility of recovering them and thereafter, I was able to do the flashing again but after doing the flashing the device would not be recognized again.
This having been my first time interacting with the Nrf52832, I can not be quite sure of what is wrong. With Nrf51, I had the ability of carrying out the flashing without issues at all. So I cannot know if the problem is associated with the Nrf52832 or with the E104-BT5052 module… and of course on my side I don’t think so. Imagine am forced to use the SWDO/SWDCLK to do the flashing so that it can work?
Am thankful.
