STM32F746GDISCOVERY and TouchGFX 4.13 problem

antonioB · ‎2020-02-26

Hi to all i have this problem, i create a simpe example with TouchGFX Designer 4.13, i use the STM32F746GDISCOVERY for my test.

I create the esample and i see all work well because i run simulator and run target all work well.

I generate the code, i open the project with CubeIde 1.3 and in folder ..Middlewares\ST\touchgfx copy the files present in TouchGFX folder,

If i build the project i don't have error this is the output:

11:11:51 **** Incremental Build of configuration Debug for project STM32F746G_DISCO ****

make -j8 all

arm-none-eabi-size STM32F746G_DISCO.elf

Finished building: default.size.stdout

11:12:14 Build Finished. 0 errors, 0 warnings. (took 22s.711ms)

if i run the debug i have this error:

i don't know where is the problem

can you help me?

Do you have any breakpoints set in the QSPI flash memory at 0x90000000ish?

First try removing all breakpoint using the Breakpoints view.

Does that help?

If not, try to remove the debug configuration and create a new one with default settings. You may also disable the checkbox "set breakpint at main" and "Resume" on the startup tab of the debug config to see if you are able to step into the Reset_Handler without problems?!

Not working?

What if you try using OpenOCD instead instead of ST-LINK GDB server as the probe choice in the debug config?

Hi, i clear all breakpoint, but don't fix it.

i use OpenCD and i have this message:

and this immage

you can see that i don't run the resume, if I comment the scheduler

// osKernelStart();

I always have the same problem, don't run the program
