nrfjprog: cannot combine --reset with --program?

Does this also break the Nordic DFU BLE bootloader example (dual_bank_ble_s110_pca10028), for the same reason? The suggested settings include both --reset and --program, and because the configuration dialog admits only one command, splitting the command as suggested above can't be used as a workaround.

ahha, misunderstood. Yes yes, hang on, we are very soon there, lot of redesign has been done to achieve that goal. Can't say anything more than that :)

I meant cross-platform as in OS - my understanding is that this program does not exist on OS X or Linux?

nrfjprog will only be for nRF (Nordic) chips. The latest version supports nRF51 and nRF52. We do not support any other platforms.

Nice to know. I hope you will consider making nrfjprog cross-platform.

nrfjprog internally uses JLink dll but wraps a lot of useful and safe operations that are not present directly with Jlink. You can very easily write a script in Jlink and brick your device, nrfjprog does many checks that prevents unsafe operations. We recommend you to use JLink directly if you are sure of what you are doing.

Thanks. I've switched to segger jlink for this step. Is there anything nrfjprog does that jlink cannot do in the context of nRF-DK? It might be better for Nordic to just recommend jlink since it's cross-platform, unlike nrfjprog.

Yes , they are broken, I'll create a bug for it. I hope that you can continue with your development with this modification in your scripts.

Thanks. But doesn't that mean that the Nordic example Makefiles are broken? They combine the options.

It has changed and it is now not allowed to mix reset with programming the chip. I am not sure the reason behind this. You can just split your command and it should work.

nrfjprog --program _build/nrf51422_xxac_s110.hex
nrfjprog --reset
