• Provide a minimal code snippet example that reproduces the bug. Please make sure you wrap any code in the proper code blocks like below

SPIFlash flash;

typedef struct {
  uint32_t a;
  uint32_t b;
  uint32_t c;
} Test;


void setup() {
  Serial.begin(115200);
  flash.begin();
  uint32_t addr = 250;
  Test data_w;
  Test data_r;
  flash.eraseBlock32K(addr);
    data_w.a = 1;
    data_w.b = 2;
    data_w.c = 3;
    flash.writeAnything(addr,data_w);
    flash.readAnything(addr, data_r);
    Serial.print(data_r.a);Serial.print("\t");
    Serial.print(data_r.b);Serial.print("\t");
    Serial.println(data_r.c);
}

void loop() {}   ```

###### ---------------------------- suggestions how to fix  ----------------------------

SPIFlash.h  Insert code in line numbers 315 

         if(_currentAddress % SPI_PAGESIZE==0){//<<<<<<<<<<<<<<<<<
		CHIP_SELECT
		_nextByte(WRITE, PAGEPROG);
		_transferAddress();
	  }

Thanks for catching this. Page boundary bugs are turning out to be the bane of my existence 😉

I'll roll the fix into the next release.

Hi all, i'm getting failed (Write Function has failed errorcheck) on structTest() with Spansion/Cypress S25FL164K, running on ATSAMD21E18A. Any suggestions for further troubleshooting? Thanks in advance.

Please ignore, it was just a temporary issue. Mentioned flash is working fine.
