Hello Morgan, I am also using BL600 with nordic stack. Can you tell me the method to flash bootloader? Currently I am flashing Softdevice using nRFgo Studio and application using Keil/nRFgo studio. If I have to flash bootloader, do I have to flash SD and Bootloader and then application?

We got it figured out. It turns out that the app was booting correctly, but then immediately resetting. So the problem was with the app instead of the bootloader.

Interestingly, starting the app through gdb worked properly, but loading the hex file using a bootloader or nRFGo did not work. That's why we never saw the issue before trying with the bootloader. The line that was causing a hard fault was:

NRF_CLOCK->EVENTS_HFCLKSTARTED = 0;

I do not have the BL600 module here to test, but your setup works on my development kit. I do not realize why this is not working on the BL600 module since it has the second revision of the chip. Can you ask Laird to verify your setup on their side?

Thanks Stefan,

We've confirmed with Laird that the modules that we have use the XLR2 silicon. We have also tested this with the SD7.0.0, and it still doesn't work.

What else can we try to get this working?

Thanks!

Update 28.11.2014 I'm using an Android phone with version 2.0.3 of nRF Master Control Panel. This has also worked well with other nRF51822 boards I've built. The only issues I'm having are with the Laird Module.

The SDK6.1 should work with softdevice S110 v7.0.0 and second revision of the nRF51822. The question is what hardware revision is on your BL600 module? The BL600 had first nRF51822 revision to begin with. Is there any version number on the BL600 module? If you find one, I recommend to contact Laird technologies in order to find out what nRF51822 hardware revision is on your BL600 module.

Update 27.11.2014 When running the second revision hardware the bootloader in nRF51 SDK 6.1.0 should work with softdevice S110 v7.0.0 and Master Control Panel v3.7.0 or later. I think it should also work for the latest nRF Toolbox DFU for Android and IOS. What central device are you using for the DFU?
