Description
Describe your problem.
Board fails SerialFlash hardware test. Additionally, I am unable to create new files in flash memory despite SerialFlash.begin(); returning true and the appearance of successful communication with the flash chip.
Steps To Reproduce Problem
Please give detailed instructions needed for anyone to attempt to reproduce the problem.
Hardware & Software
Board
Rocket Scream Mini Ultra Pro V2 (DEV-00064)
Shields / modules used
None
Arduino IDE version
1.8.15
Teensyduino version (if using Teensy)
Version info & package name (from Tools > Boards > Board Manager)
Arduino AVR Boards 1.8.3
Operating system & version
macOS Catalina 10.15.7
Any other software or hardware?
Arduino Sketch
// Change the code below by your sketch (please try to give the smallest code which demonstrates the problem)
#include <Arduino.h>
// libraries: give links/details so anyone can compile your code for the same result
// RawHardwareTest - Check if a SPI Flash chip is compatible
// with SerialFlash by performing many read and write tests
// to its memory.
//
// The chip should be fully erased before running this test.
// Use the EraseEverything to do a (slow) full chip erase.
//
// Normally you should NOT access the flash memory directly,
// as this test program does. You should create files and
// read and write the files. File creation allocates space
// with program & erase boundaries within the chip, to allow
// reading from any other files while a file is busy writing
// or erasing (if created as erasable).
//
// If you discover an incompatible chip, please report it here:
// https://github.com/PaulStoffregen/SerialFlash/issues
// You MUST post the complete output of this program, and
// the exact part number and manufacturer of the chip.
