SD card - Ixox/preenfm3 GitHub Wiki

This is a minimal doc for the moment, don't hesistate to use the forum for any questions.

Some old SD card does not work at all (error #6), all recent cards i tried worked without problem : Sandisk 16Go standard and Ultra work great and cand be found for around 6 Euros.

If you have problems, make sure you format it with FAT32 filesystem with the the official SD formater.
Your SD card must contains a /pfm3 folder.
Download the pfm3_SD.zip file attached to the v0.105 release here, and extract files on the SD card.

DX7 sysex can be read and DX7 parameters are roughly map to the preenfm3 parameters. That can be a good start to create a new preset, but don't expect great DX7 emulation.
Only 4104 bytes sysex dumps with 32 presets are readable.
You can find a big archive of those files here. DX7 sysex files must be copied in the /pfm3/DX7 folder

If you want to flash a firmware using the pfm3 bootloader, firmware "bin" files must be in the SDcard root folder "/".
To enter bootloader, please follow the instructions at the bottom of this page : https://github.com/Ixox/preenfm3/wiki/Flash.
