Spider v2.3 flash

I’m trying to set up a new build with a spider v2.3 board on RatOS because I’ve only used Fluidd on past machines and want to give RatOS/Mainsail a try. I realize my build is a bit custom but I’m trying it anyway. Q: will a 2.3 board flash with the firmware build in RatOS for a 1.1 board? I’d prefer to flash over USB without an SDcard but after setting jumpers to 5.5v/USB and 3.3/Boot0 I’m able to get an ls serial by ID for the board and I can see it in lsusb, but the make flash FLASH_DEVICE:0483:df11 command fails in the dfu utility error 255 Any suggestions? ✌️
