I'm using MQX 4.1 on K70 with an external Nandflash linked to the NFC.
I open this device and mount a device ("a:") and then use to store a big file resource used by PEG (400 000 Bytes)
Also, for my application, I want save some parameter in a file.
Then I open a file, save some data and close the file.
But after a power off/On, data are note saved in the file. I must close the MFS.
But I think If I close to re open, My PEG resource could not run correctly..
Is mandatory to close the MFS to save definitely a file into the Nandflash?
How work the MFS? When data are realy saved in the nandflash?
