Bug reports only

• If this is a bug report -

• Make sure you have run FlashDiagnostics.ino with #define RUNDIAGNOSTICS uncommented in SPIFlash.h. List any error codes that pop up in your Serial output when you run FlashDiagnostics.ino.here:
  Error codes

• If you have a problem with a particular function, call the flash.error() function (after you have made sure you have started up your Serial port with a Serial.begin(BAUD) ). Provide details of the function, the data given to/ expected from the function and the error code here: (Please repeat this for every function you have an error with*)

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

i have run FlashDiagnostics and its successfully no Error
I try write and then read back its success

I'm afraid the STM32F105xx is currently not officially supported as I do not have the dev board. I will keep this issue open in case someone who has an STM32F105xx dev board can help with a fix.

P.S. I've got my hands on a STM32F105xx dev board and v3.4.0 appears to work fine now 🙂
