Outboard DFU Error - Host incompatible

Hardware
1

Trying to do Outboard DFU update and getting the following error in Notehub:

{
    "text": "DFU of host firmware aborted: cannot update host: loader: binpack type esp32 is not compatible with host esp3on':'1.0.0','built':'Apr 19 2023 15"
}

Here is the command I used to build the bin pack:

Karls-iWell-Macbook:Notecard CLI karlnicholas$ ~/OneDrive/"Blues Wireless"/"Notecard CLI"/notecard -binpack esp32 0x1000:sketch_RS485_Test_v2.ino.bin 0x8000:sketch_RS485_Test_v2.ino.bin 0x10000:sketch_RS485_Test_v2.ino.bin

2023-04-19-201641.binpack now incorporates 3 files and is 700431 bytes (34% saved because of compression):

HOST: esp32

I compiled my version 1 code using Arduino IDE and downloaded onto host (Adafruit Feather Huzzah 32). Simply changed version number in v2 and compiled using Arduino IDE, then built bin pack as shown above.

I don’t know where “esp3on” for host in error message is coming from.

Any ideas?

Thanks,

This may a false alarm. In the test described, I had the DFU switch on and was using the default connections between Notecard and host.

I turned DFU off, used the connections described in https://discuss.blues.com/t/esp32-s2-outboard-dfu/1125 and it is now writing the new version to the host.

Still debugging, the host is not successfully updating, but I made it past this hurdle.
