Hey!When I use images in TouchGFX, the color sequence seems different than in regular widgets. It only appears when images are stored on external flash (QSPI flash in my case), images stored on internal flash are fine.Below is an example: the top 3 s...

Hey!I'm trying to use ST-LINK/V2-1 from Nucleo to program and debug my board. I removed the jumpers from CN2 and connected CN4 to my board according to the manual:Problem occurs when I tie NRST of the CN4 to the STM32 on my board - in this case "DEV...

Hey!I initialized the TIM1 peripheral to output an complementary PWN signal on channel 2 (PB14) and tested it with an oscilloscope. Signal is present, everything's fine.Then after initialization of the SPI2 peripheral (PB13 & PB15) PWM signal is no l...

I'm completely lost in ADC working modes. And it happens EACH time I start a new project with internal ADC. So it ends up taking a lot of time to get the ADC do what I want.I need the following behaviour: 2 channels of single adc runs forever.By my r...

Thanks for the reply. The problem dissapeared, but I'm not sure how. I'm guessing this is due to a mismatch between the pixel format settings in CubeMX and TouchGFX here:

Well, I'd try disabling TouchGFX and fill the framebuffer with some simple pattern in RGB565 mode to make sure the display is showing what is expected and the hardware settings are ok.

In CubeMX check DSIHOST -> Color coding if not already. If didn't help, maybe try disable DMA2D for now - I'm just guessing.

Thx for response.Even though I moved all the code to internal flash and the project compiled successfully, my linker script still had an ExtFlashSection. After clearing the linker file - the code runs.

Got the same problem with STM32H750-based custom board. TouchGFX version 4.23.0, never had this problem on earlier versions like 2 years ago.OP's error message pops up while trying to Run code from CubeIDE.CubeProgrammer also fails to program MCU wit...
