Good afternoon, I have developed a custom board based on nRF51822 device and SD-110-v8. For debugging I have been usign the Ulink2 tool with Keil. Now, I want to implement DFU on my custom device but I have problems to program the DFU Bootloader into my device with my debuggin tool. So, is there any way of programming the DFU without a Segger tool (to access UICR) and continue using my ULINK2? If not, which Segger debugger do you recommend the most? The solution should also think in the future production stage.
