Hi,
I'm working on a TouchGFX ( version 4.18.1) project using the STM32F746IGT6 controller.. The issue I’m facing occurs intermittently — the code sometimes fails to enter the while loop inside int main(). During debugging, I noticed that the entire code is executing and suddenly the console repeatedly displays the following message:
Target is not responding, retrying...
Target is not responding, retrying...
Target is not responding, retrying...
Target is not responding, retrying...
Although the system doesn’t shut down, the display freezes as a result. When I pause the execution and step through the code, it appears to be looping within the ISR, and I see the message:0x080bec0e in touchgfx::ConstFont::find(unsigned short) const () set *(int *)0xE000EDFC=*(int *)0xE000EDFC|0x7F0.
For reference, here are the hardware components used:
External Flash: IS25LP512M-JLLE-TR
SDRAM: NDS63PT9-16IT
The screen freeze also happens even when the code is not in debug mode.
I would appreciate immediate assistance in resolving this issue.
