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.

Hi Ishgum,

You mentioned you erased the board. How would the previous bootloader has anything to do here ?

Could you list exactly the command you used and all the log you get ? How do you build the bootloader, which S132 version you use. Please list your steps as detailed as possible.
