I am using the legacy bootloader, SDK 11.0 with SD 2.0, S132
The example Bootloader DFU images part of SDK 11.0 load just fine (I'm using nRF Connect Android app), however when I create my own package, I see "[DFU] Remote DFU error: OPERATION FAILED."
I used the following command: "$ nrfutil pkg generate --bootloader bootloader.hex --bootloader-version 0x11 --sd-req 0x81 bootloader.zip"

More info:
I looked at the nrf_err_code_translate(...) in "dfu_transport_ble.c" and the err_code seen is "9" (NRF_ERROR_INVALID_LENGTH)
