Writing/reading struct to/from flash.

[jeromeDms]

Hi there, I have a C struct that I would like to save to flash. I do not see in fmc.h any function to read/write flash, passing a pointer and data Len to write/read.

My struct is as follow :

typedef struct
{
    uint8_t midiInRouting[MIDI_DEV_MAX_USB_NUM_CABLES * 2];       
    uint16_t filterChannels[MIDI_DEV_MAX_USB_NUM_CABLES * 2];
    uint8_t filterStatus[MIDI_DEV_MAX_USB_NUM_CABLES * 2][MAX_FILTER_STATUS];
} _snvSettings;

Any tip to achieve this ? Thanks

Hi,

Please try FMC_Read(...) and FMC_Write(...) function for flash read/write by passing a pointer instead of address.

Not sure to understand. FMC_Read reads a single word from flash, how can I fill my entire struct by reading a single word ?

You can implement a function to utilize FMC_Read function by changing the address to achieve this purpose.
