@ajb2k3 looks like your almost there, here's how mine is set up, you need to make sure you put the folder that contains all of the firmware files for the camera firmware into the firmwares folder with all the other firmwares. Then remember what you named the folder and put that folder in the path name. The m5 cam firmware requires three files (bootloader.bin, partitions_singleapp.bin and camera.bin) heres what mine looks like, I will try to get the burner uploaded with the firmware included.

        "name": "M5Cam-psram",
        "version": "M5Cam-psram",
        "path": "M5Flow\\M5Cam-psram",
        "commands": [
            "--chip esp32 --port %port --baud %baud write_flash -z 0x1000 %PATH\\bootloader.bin 0x8000 %PATH\\partitions_singleapp.bin 0x10000 %PATH\\camera.bin"
        ]
    }

Thanks, I was confused over the files and mem locations.

        "name": "M5Cam-psram",

            "--chip esp32 --port %port --baud %baud write_flash -z 0x1000 %PATH\\bootloader.bin 0x8000 %PATH\\partitions_singleapp.bin 0x10000 %PATH\\camera.bin"
        ]
