CR-FDM-V2.5.S1 on the CR10 Smart menuconfig setting

I have been trying for a few days now to find the correct combination for the CR-FDM-V2.5.S1 mainboard. so that the printer will accept the firmware. The same board in the cr10smart pro settings do not work. this bard seems to have started shipping with the cr10 smart systems not long after the cr10 smart pro came out. but I am not finding setup to get the cr10 smart with that newer board working.

I have tried several combinations. from 28 - 64 Kib boot loader. but nothing seems to be working. I am also unsure of the GIPO setting. the ARM processor I know I have correct because that is what is stamped on it. I have not been able to get the firmware on the printer, to even start testing the pinning matchup. I know the zyxe steps will be off because the steps are off on the printer when you load the smart pro firmware on it.

OMG I am stupid. I had been trying and trying and I miss one simple statement in the configuration file.
"and must not match the last filename

that was flashed."

I tried one fiel name over and over. not know that it was the same one bad in the beginning.

Hi, just to be clear, did the CR10 Smart Pro settings work for you in the end? I’m having a difficult time with my CR-10 Smart (non-pro edition) taking the firmware.
