Bug Report: Writing struct after Flash erase sector not working.

[koulombus]

Hi,

SPIFlash Version: 3.0.1
Arduino IDE: 1.8.5
OS: Mac 10.13.3
Arduino Board: mega2560
Flash: Winbond: W25Q80BV 1MB

Before I write the struct to flash I do a flash.eraseSector() on page 0.
After check page 0 the values are not stored.
When I do the same with chip erase, all is fine. But I do not always want to delete the whole chip.

The struct:

struct CONFIGURATION {
    struct MISC {
        byte tempHigh = 30;            
        byte tempLow = 20;             
        bool parkingMode = false;      
        bool allowDataToBeSent = false;
    } misc;
    struct NETWORK {
        char ssid[50] = "§";           
        char pwd[50] = "§";            
        char userid[50] = "§";         
    } network;
    struct CHARGING_INFO {
        byte interval = 5;             
        byte highChargingDefault = 80; 
    } charging;
} configuration;

Save and read :

void readConfiguration() {
    flash.readAnything(0, configuration);
}

void saveConfiguration() {
    flash.eraseChip();
    // flash.eraseSector(0);
    flash.writeAnything(0, configuration);
}

Hello !
I have the same problem

SPIFlash Version: 3.0.0
Arduino IDE: 1.8.4
OS: Win7
Arduino Board: Atmega328P
Flash: Winbond: W25Q256

The eraseChip function is working while the eraseSector function is not erasing at all
Here is the serial output of the Test flash sketch when I ask to erase the sector at address 0 :

----------------------------------------------------------------------------------------------------------------------------------
                                                       Function 11 : Erase 4KB sector                                               
                                                        SPIFlash library test

This function will erase a 4KB sector.

We should only see unwritten bytes with a value of 255 (in decimal output mode)

Hi guys, Thanks for pointing this out. I've fixed it (I think) in the latest code in the development branch. I've tested it using the new version of Struct_writer.ino in the Examples folder. 🙂

My apologies for the delay in getting back to you. I came back from a long bushwalking holiday to the start of semester at the University I work at - having 1200 first years to deal with after a month of the wilderness took a bit of getting back into!
