Touch-GFX Error & Hard Fault After Gauge Asset Update – Need Suggestions

naveen · ‎2025-06-16

Hi Team,

I’m currently working on a project involving the TouchGFX interface with an internal clock configured at 480 MHz. I’ve created a custom TouchGFX project using STM32CubeMX and successfully brought up both QSPI and SDRAM, verifying their functionality independently.

Following the guidelines from TouchGFX Seminar -3, I proceeded to enable TouchGFX through CubeMX. I've attached screenshots showing my LTDC, DMA2D, Clock, and TouchGFX configurations for your reference.

Project Details:

MCU: STM32H750IBT6
Display: 12.1-inch panel supporting RGB888
LVDS Driver: DS90C385AMTX_NOPB

Initially, with a simple background and the default designer gauge, everything worked fine.

However, when I customized the gauge's background and needle graphics, I started encountering errors, including:

TouchGFX rendering errors (specific message attached in screenshot)
Occasional Hard Fault exceptions

I would appreciate your insights on what might be causing this issue—especially whether it could be related to memory constraints, asset sizes, or configuration mismatches.

Thanks in advance for your support.

I have attached a document that includes all the screenshots of the Touch-GFX configuration steps I followed during development. If there are any mistakes in the setup, please excuse me and feel free to point them out.

Here are some screen shorts of error I got when I flashed customized gauge.
