Sammy 21C invalid firmware
-
Hello all
I picked up a couple of Sammy21C to do a little experimenting and when I power them (viaUSB) I get the following:
Invalid firmware
M115
Block receive timeout
Invalid firmware
Block receive timeout
Invalid firmware
Block receive timeout
Invalid firmware
Block receive timeoutCan any one explain whats going on? It is meant to have a Duet3D boot loader - Do I need to connect it to Main duet board (mini5+) to load something or can I load the firmware from the USB?
I just wanted to make sure the board is working - is there any M commands that it will understand as a boat loader ? Is there a way to load the firmware from USB?Thanks for your help

@Behrouz-AKT those messages mean that the bootloader is installed but no main firmware. It is trying to download firmware over CAN from a Duet 3 main board but not getting a response.
If you want to use our sample SammyC21 firmware binary, you will need to connect it to your Mini5+ and upload that binary to the Mini5+.
