Replacing bootloader through nrfjprog - Error: Single: Invalid Bank

[ishgum]

I am trying to upload a bootloader to an nRF52832 chip. (This chip is on the ruuvitag and is programmed through their developer board).

I got the bootloader working on the DK but when I tried to upload it to the Ruuvitag I get the log output: Error: Single: Invalid Bank Info: Error code - sd_ble_cfg_set: 0x00000000

The ruuvitag comes with a bootloader based on SDK 12 and SD 3. I am using SDK 13 and SD 4. I am programming using nrfjprog and compiling with GCC.

I suspect that the issue is because of some settings related to the original bootloader that gets confused when loaded with the SDK 13 bootloader, but I am really stuck.

Sorry Hung, I should've exaplained clearer. I have the Bluetooth working, and the softdevices definitely runs with no issue. The board definitely has the crystal on it too. I can get the example working such that I can see the DFU, connect to it, but when I attempt to upload the firmware to it, it fails. I'll work on getting that log output for you ASAP.
