Hi James,

What do you mean by "primary bootloader procedure" ?

nRF Connect has its own DFU you don't need to use in parallel with nRF Toolbox.

If you only test with dual_bank_ble do you have the same problem ?
If you do no other modification except for changing from dualbank to single bank, would you have the issue ? If you do , please attach your bootloader so we can test here.
