stm32h743i + touchgfx

[feelingoflight]

Hello.

Im trying to flash evaluation board STM32H743I-EVAL with help of touchgfx designer 4.10.0.

In the simplest case i create project with application template ST STM32H743I EVAL and without any elements (no backgrounds, buttons etc.).

But when i try to flash (button "run target"), i havethis:

make -f target/gcc/Makefile -j10 flash

An error occured during flash. Please make sure you have the right target connected.

ST-LINK SN: 0672FF323338424E43254935

ST-LINK Firmware version: V2J32S22 (Need Update)

Connected via SWD.

SWD Frequency = 4000K.

Target voltage = 3.2 V

Connection mode: Normal

Reset mode: Hardware reset

Device ID: 0x450

Device flash Size: 2048 Kbytes

Device family: STM32H7xx

Loading file...

Flash Programming:

File : build/bin/target.hex

Address : 0x08000000

The elf loader file is not accessible.

MCU Reset.

target/gcc/Makefile:389: recipe for target '_extflash_' failed

make[1]: *** [_extflash_] Error 12

target/gcc/Makefile:77: recipe for target 'flash' failed

make: *** [flash] Error 2

And i tried to update ST-LINK firmware, it doesnt help and debug log still displays the message "need update".

Help me pls to fix my problem, how to flash stm32h743i?

Okay, so it's worse than before?

Another note on what i saw in the video. The reason you're seeing something different when you press the button is because you're running a double buffering setup and the other framebuffer has a different kind of garbage.

[feelingoflight]

Yes, i know about garbage, its not a problem.

Problem now:

To flash firmware i should write code in EWARM, then compile code in touchgfx and then flash it from st-link.

I would like to write code and generate hex file in iar, and then flash it from st-link.

But when i flash iar-generated hex file i see only old buffer garbage.

I had a similar problem using STM32F746G-DISCO with new TouchGFX 4.13.0 version.

I open the TouchGFX designer, generate a template for this discovery kit and click run target but I had the folowing error:

Flash
        make -f ../gcc/Makefile flash
        Linking TouchGFX/build/bin/target.elf
        Producing additional output formats...
          target.hex   - Combined internal+external hex
          intflash.elf - Internal flash, elf debug
          intflash.hex - Internal flash, hex
          extflash.bin - External flash, binary
        /usr/bin/sh: C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe: No such file or directory
        gcc/Makefile:284: recipe for target '_extflash_' failed
        make[1]: *** [_extflash_] Error 127
        ../gcc/Makefile:50: recipe for target 'flash' failed
        make: *** [flash] Error 2
        Failed

The error is because I don´t have STM32CubeProgrammer carpet into my STMicroelectronics\STM32Cube files path and so I don't have the correct STM32_Programmer_CLI.exe file.

To fix it I went to the the make file in MyApplication (../TouchGFXProjects/MyApplication/gcc/Makefile) and modify the path to my STM32 Cli programmer (that will have a different name because I will use the ST-Link Utility STM32 Cli programmer because I don´t have STM32 Cube Programmer).

In my make file I changed:

stm32cubeProgrammer := STMicroelectronics\\STM32Cube\\STM32CubeProgrammer\\bin\\STM32_Programmer_CLI.exe
 
to
 
stm32cubeProgrammer := STMicroelectronics\\STM32 ST-LINK Utility\\ST-LINK Utility\\ST-LINK_CLI.exe
 
AND
 
stm32cubeLoader := STMicroelectronics\\STM32Cube\\STM32CubeProgrammer\\bin\\ExternalLoader\\N25Q128A_STM32F746G-DISCO.stldr
 
to
 
stm32cubeLoader := STMicroelectronics\\STM32 ST-LINK Utility\\ST-LINK Utility\\ExternalLoader\\N25Q128A_STM32F746G-DISCO.stldr

Then the first error was resolved but a new was raised:

        make -f ../gcc/Makefile flash
        Linking TouchGFX/build/bin/target.elf
        Producing additional output formats...

        ../gcc/Makefile:50: recipe for target 'flash' failed
        make: *** [flash] Error 2
        Failed
    Failed

This is because I am using the ST-LINK_CLI.exe STM32 programmer instead of STM32_Programmer_CLI.exe, so the command syntax is different. Parameter "port=SWD" doesn't exists. To fix it I changed:

_extflash_:
	@$(st_stm32cube_programmer) -c port=SWD -d $(binary_output_path)/target.hex -el $(st_stm32cube_external_loader) -hardRst
 
to 
 
_extflash_:
	@$(st_stm32cube_programmer) -c SWD -d $(binary_output_path)/target.hex -el $(st_stm32cube_external_loader) -hardRst

But another error was raised:

        make: *** [flash] Error 2
        Failed
    Failed

This is because [-d] signal the path to the target file in STM32_Programmer_CLI.exe but not in ST-LINK_CLI.exe. So I changed:

@$(st_stm32cube_programmer) -c SWD -d $(binary_output_path)/target.hex -el $(st_stm32cube_external_loader) -hardRst
 
to 
 
@$(st_stm32cube_programmer) -c SWD -p $(binary_output_path)/target.hex -el $(st_stm32cube_external_loader) -hardRst

Now I am developing my applications normally!

P.D.

1.- If you will flash in internal flash it is a must change the commands for _intflash too.

2.- I am using:

2.1.- STM32CubeMX Version 5.5.0 with TouchGFX Generator (4.13.0) X-CUBE-TOUCHGFX STMicroelectronics packages installed.

2.2.- STM32 ST-Link Utility v4.5.0.0

2.3.- STLinkUSBDriver.dll v5.1.2.0

2.4.- ST-LINK_CLI.exe v3.5.0.0

2.5.- TouchGFX designer 4.13.0 installed from within CubeMX.

Bests regards,

Juan
