    Dear guys,

I'm new in the forum, so let me introduce myself.
I m an hardware ingineer in a french company.
I'm not famillar with S12X micro controller. I 'm used to design with ARM9 processor.
For A customer, I must use a S12XDP512 proc. The customer wants to interface a flash memory like SDcard, and store some log datas on it. He also wants the data to be easily red in a Windows system.

In my opinion, the SD memory can be interfaced with the S12X with the SPI bus. It want be a problem I think. But I don't know how to organize  the datas in the SD card. Doesn't somebody has already used a file system  like FAT (or another file system readable by Windows) with a S12X. I'm afraid that FAT will be to large for the MCU flash memory!!

Thanks a lot for your help.
