Yeah I unlock and lock the flash before and after, make sure the flash busyflag isnt high, Ive also used the HAL and SPL flash word functions which do all that, and a function I wrote myself which does the above and enable programming bit etc, and always the same outcome, I can write to 0x0801D5F2 but not 0x0801d5F0

Hello, I figured out my problem late last night, it was trusting a HAL driver, there was an error in there, can I delete the question? as not needed anymore

Hello again @Tim Jordan​,

Glad you found the solution to your problem!

So, we would appreciate it if you can re-edit your post and also add a comment explaining how did you fix it, and further explain the error in the HAL driver so we can test it and fix it if confirmed!

Thank you!
