Solved: My STM32G473 Has Wrong Flash Size? How Do I Deal W... - STMicroelectronics Community This extra flash causes some confusion because datasheet is very ambiguous on this topic. quote from stm32g473xb/c/e datasheet: "the stm32g473xb/xc/xe devices feature 512 kbytes of embedded flash memory which is available for storing programs and data.". If the flash size is correct then you have nothing to worry about, but you can override this value if you wish by changing the size parameter to the flash bank cmd. also make sure you are using the latest version of openocd as we have fixed a few issues with the stm32 flash driver.

Manuals and user guides for st stm32g473. we have 2 st stm32g473 manuals available for free pdf download: reference manual st stm32g473 reference manual (2126 pages). This size is wrong: the chip has 1mib of flash. i've also tried this on another chip, the one on stm32f407g disc1, and st info flash reports flash size of 0x3fffc00, which would be almost 64mib!. In this guide, you’ll learn how flash works in stm32 microcontrollers and how to use stm32 hal functions for flash write, erase, and read operations. this tutorial is divided into two sections for clarity and relevance.

Resolved! my stm32g473 has wrong flash size? how do i deal with this? i have stm32g473vct6 mcu. according to part number this device should have 256kb flash (size code c). flash size register (0x1fff75e0) also shows 256kb (reg. value 0x100). however i can read and successfully write 512kb of data. stm32cubeprogrammer a 2021 12 20 05:46 am |. Hi @xeenych, i hope you are fine. the issue you reported has been fixed in the frame of version v1.10.3 of the stm32cubel1 published recently on github. thank you again for having reported. with regards,. If start of your flash data block is correct aligned you don't need this check because all multplied 64bit data are always aligned. so you can link the start address of your union to page 40 in your example (see code below). When i was stepping the code (the code is pretty simple and straight forward) in the debugger, there was absolutely no problem indicated in flash sr, the operation completed successfully, but the expected pages weren't in fact erased, and consequent writes failed as one would expect.
