STM32 Flash Loader Demonstrator - Support for STM32F76X

Hi Everyone,

I was looking for a tool that was able to bootload an STM32F767 microcontroller via USART which I thought I found when I came across the STM Flash Loader Demonstrator (version 2.8.0). However, there was no '.STMap' memory map file for this processor family, the closest was STM32F74X/5X.  

I created a new memory map file for the 

STM32F767 (see attached) which allowed me to successfully connect to my micro using the Flash Loader Demonstrator. However, I cannot perform an erase, program or download. The error message that I receive says 'Fail. Check read/write protections'. However, when checking the flash readout and write protections they are disabled. 

Has anyone had success getting this flash loader tool to work for STM32F76X parts?

Also, does anyone know the meaning and significance of 'BID' in an '.STMap' file? I am currently using 'BID' for

STM32F74X/5X parts - maybe this could be the source of the problem?

Hi, problem resolved.

I change STMap file as:

[Product]

Name=STM32F7_46_1024K_RAM

PID=0449

BID=1FF0EDBE

FlashSize=0400    ;;ADDR_FLASH_SIZE=FFFFFFFF;  TO BE DONE !!!!

PacketSize=80

ACKVAL=79

MAPNAME=Sectors

PagesPerSector=1

family = 6;

;; InternalRAM

[InternalRAM]

Name=userRAM

Address=20010000

Size=0001D000

Type=111

UFO=111

Hi

,

You find attached a newer version of the FlashLoader demonstrator supporting STM32F7 devices.

Please try it and keep me informed if it is working as expected or you faced any issue using it.

This version will be available soon on the web.

Also, does anyone know the meaning and significance of 'BID' in an '.STMap' file?

BID: it is the Bootloader ID.

The information about its value for each product could be found in

Hi

I am going to program qspi flash using UART boatloader that can use for future update from internet,

My MCU is STM32F746BG, I change sample project of AN2606 and make new .bin file. but i can not program RAM of stm32f746 using flash loader.

i get Error: can not erase or can not download.

0690X00000603tmQAA.jpg

I change  .STmap file for my MCU:

;;-------

[Product]

Name=STM32F7_46_1024K

PID=0449

BID=1FF0EDBE

FlashSize=0400    ;;ADDR_FLASH_SIZE=FFFFFFFF;  TO BE DONE !!!!

PacketSize=80

ACKVAL=79

MAPNAME=Sectors

PagesPerSector=1

family = 6;

;; InternalRAM

[InternalRAM]

Name=userRAM

Address=20003000

Size=0001D000

Type=111

UFO=111

;;---------

what is wrong?

They don't, it has been replaced/superseded with the STM32 Cube Programmer in USART mode

The protocol remains the same so you could use your own solutions too.
