unable to download larger bootloader

Allen

Hello,

Is there any DFU package that can be created that would enable downloading a larger bootloader? In this case, we have the non-debug bootloader loaded and want to switch to the debug version of the bootloader via a DFU download. These are "sealed" units.

    Speaking of updating the UICR, there seems to be some magic there I am missing when reflashing the entire chip. I have a script that does an eraseall, then reloads all the software components. When the script completes it will not boot. If I then open NRFgo and select "nRF5x Programming" it suddenly comes to life. What is happening and how can I incorporate that in a script? I have a feeling it has something to do with the UICR registers.
