MCU don't run after out of debug

Postby forcewin » Wed Jul 03, 2019 2:31 pm

I am still using truestudio, stm32cubeMx and stm32F746.
By the way, suddenly the MCUs are not working.
It works fine in debug mode, but stops when you exit debug mode.

I can reinstall truestudio and cubemx,
and also erased various vaccine programs...
I am trying to modify the debug configuration for a few days.
What should I do?

I fail again today.
The ST-LINK driver is working well
startup scripts also seem to be wrong.
I do not see the word error.
Debug is also good. Very very good
But, when debug is finished, mcu is halt-halt-halt... endless stopping~.
The same is true if finished quit after load.
Sky and earth do not open the way.

startup scripts:
monitor flash set_parallelism_mode 2
set *0xE0042004 = (*0xE0042004) | 0x7
tbreak main

Output format: Intel Hex

C/C++ Build / Settings / Build Steps

STM32 ST-LINK Utility.exe file:
open my .hex file -> Program & verify -> Start

But, why is the MCU stopped ?
Let me know this, please.

no problem in debug mode..

ST-LINK =HALT_MODE appears in Truestudio's log file
I found Core state: Halted in the STM32 ST-LINK Utility program
After loading the hex file, enter halt_mode.
I do not know why.
It's too hard to start the MCU program right now.
Downgrade stm32cubeMx and try installing again.
Downgrade cubemx and try installing again.
I also install the stm32f7 series in the old version.
Can not be done, how can I do...?
