RL-FlashFS - fformat options LOW and LOW_EB

Hi All,

I'm currently working on an old project with uVision4.60

I'm using the RL-FlashFS with an SD card. I have the majority of the file maintenance routines working including fformat where I can use the options FAT32 and WIPE.

I cannot however get the LOW or LOW_EB options to work (see link below). Does anybody know whether these are later additions to the fformat function?

Thanks
