Firmware v105 for DFB1X? Removing the ROM?

[exxos]

Excuse my ignorance: Does this mean I can leave the TOS ROM in place IF they are both (flashed and physical) 4.04?

Yes that's the whole idea.. You also need to solder the wire as shown in the install page.

So when the DFB1X is disabled, it disables the flash and enables the ROM..

@exxos Chris, thanks for your response and sorry for the confusion. Yes, I understand that if I update the firmware on the DFB1X I'd need to solder the wire.

My question is: If I do NOT update the firmware AND both flash/physical ROM are the same can I leave the physical ROM in place UNTIL I figure out how to safely flash the firmware to v150. If/when I I update the firmware I would solder the wire.

I don't intend to use any other versions of TOS (emuTOS etc) until I flash the firmware and solder the wire.

With below 105 firmware versions..

You have to have the ROM in order to flash. The DFB1X has to be disabled for the flash to program.

After flashing and you enable the booster, you have to remove the ROM otherwise you will have a conflict between flash and ROM.

If they are the same version then it can work.. BUT I don't recommend doing that.. Its unknown if there is a transitional conflict between the ROM and flash as both get enabled at the same time. I may be wrong but I wouldn't risk it.

ROM / FLASH has nothing to do with programming firmware anyway. Just flash the flash and remove the ROM..

I received my Waveshare Electronics Platform Cable USB programmer.

I watched @Badwolf Building the DFB1r5 -- Part 2: Acceleration video on Youtube where he programs the Xilinx to try to confirm his connections between the programmer and DFB1 but his connector differs slightly from mine.

Before I fry something can anyone confirm that I connect in this order:

DFB1-----PROGRAMMER
3V3----->VCC
GND----->GND
TCK----->TCK
TDO----->TDO
TDI----->TDI
TMS----->TMS

Per @exxos's earlier post since I need to have the Falcon powered on during the process so I want to be certain of the connections.

Yeah you just wire them like for like from DFB1X to the programmer.
