STM32F407 with ST-Link

[Alan_37]

Hi

I have a problem programming STM32 with ST-Link via flowcode,
So here is the problem if in my program I init SPI to work with ILI9341 Display flowcode does not detect target via ST-Link
if I use st-link Utility ( GUI version ) it works fine .

I think is because ST-Link utility resets the MCU exactly before programming it .

Is it possible to make flowcode do the same?

Hi
If you have the reset pin connected to the ST-LINK, you could try this ...
Edit the stm32prog.bat file found in C:\Program Files (x86)\Flowcode\Common\Compilers\starm\batch
Add the -HardRst command to the programmer line

Code: Select all

@ST-LINK_CLI.exe -HardRst -P "%MX_LOCATION%%MX_PROJECT%.hex" -Run

Let us know if that works for you.

Thanks for your reply

I have done that, but it does not work so I was wrong must be something alse
any idea why this happening?

In my experience it does seem easy to "crash" the ST-LINK, driven from command line tool, irrespective of Flowcode.
Most successful sequence is: connect ST-LINK to target, apply power to target, connect ST-LINK to PC USB, invoke ST-LINK_CLI
