Error when trying to program user app into nrf52840

[Mitch996]

Hello, I can program properly (the "--verify" command passed) my softdevice s140 into the chip, using nrfjprog 9.x. But now I can't use my keil uv5 to program my user app into the chip.

I suspect that I did not properly configure the flash range my user app can be programmed to, because I did not configure that at all.

So can someone tell me where I can find such related tutorials? Or if you are kind enough to tell me what range to go for?

Also, I don't have to worry about the range of the softdevice, nrfjprog takes care of that, right? Or do I still have to modify an ini file somewhere?

If you use NRFTOOLS (nRFgo Studio or nrfjprog) then they typically take care about Soft Device and APP HEX files (nrfjprog will force you to merge them before flashing, it will also give you error if regions overlap etc.) When it comes to memory regions' setting in Keil then you can use this blog post about memory management in Keil, just look into nRF52840 documentation (S140) on Infocenter to get correct values.

"nrfjprog will force you to merge them before flashing,"

Hello, is there a comprehensive tutorial on nrfjprog somewhere handy? Thank you and sorry to bother you again.

edit: also, the "just look into nRF52840 documentation (S140) on Infocenter to get correct values." it appears that no official techdoc for s140 has been formerly released, there is one for S132 though, are they the same?

The "force" is maybe too strong wording, it basically expects chip erased before flashing any HEX file so that kind of makes you to merge all HEX files before you erase and flash the chip;) Documentation is indeed on Infocenter (as almost everything else from Nordic;). Good luck!

When it comes to SoftDevice documentation, flash and other requirements are in Release Note which is in each release even in beta (I see "s140_nrf52840_5.0.0-3.alpha_release-notes.pdf" in the ZIP when you download SD).

Hello, I walked through the document but there is no information on the memory range setup in keil uv5?
