Error handling or return value? #20

Hi, this is nice libary.

But I found if I build a simple struct like:

struct sct_script {
    char content[40][650];
} sct_actionScript;

FlashStorage(script_store, sct_script);

but if read the script_store before the script_store not write anything yet.

It cause arduino freeze and not able keep running until reset manually.

I tracking the code find read using memcpy(data, (const void *)flash_ptr, size);

but I have no idea to handling memcpy return status code.

Whould you like to share a complete sketch?

BTW it looks like that the content array is very big 40*650 = 26000 it tooks more than 26KB of RAM, are you sure you're not running out of memory?

Sorry for late replied, I'm using ATSAMD21 which has 32KB RAM,

I notice the freeze behavior may cause by out of memory too.

So that I just attach EEPROM IC to solve the memory size problem.
