External Loader for STM32G0B0CET6

We have developed an application with LCD display in which we use TouchGFX and external SPI flash memory, the microcontroller used is STM32G0B0CET6.I wrote an external loader for STM32G070RBT6 (tested and worked) and simply rewrote it for STM32G0B0CE...

Resolved! Unable to flash TouchGFX App on Riverdi RVT70HSSNWC00-B

Hello,I've bought the Riverdi RVT70HSSNWC00-B STM32H7 embedded display.But i'm unable to flash my app to the board.Here are the log from touchGFX : ------------------------------------------------------------------- ...

Resolved! External loader fails to download

Hi all,I'm trying to put some TouchGFX data (images, text, ...) in an external flash (S25FL128L) on a custom board with STM32H7B0VB mcu. I'm using the octo-spi peripheral as quad-spi.So, I follow the guide to make an external loader and I did it. It ...

Resolved! Custom External Loader can pass the test but doesn't work with STM32CubeProgrammer

Hello, I am trying to create external loader for MX25L12835F flash memory. My MCU is STM32H7B0RBTx and I followed "External QSPI loader how to" video series on Youtube. I used source files from the Github link that is shared below the videos. I had t...

How does Mode, View, Presentor work?

I have implemented a keyboard and I am trying to keep the text that I have input in to the text areas when I switch between screens. I have read about MVP on the official touchGFX website and I have also watched some tutorials about it and I still do...

Resolved! Problems with custom external loader for W25Q16 spi flash.

Hello everyone, I've got custom-made board with STM32F407VE and W25Q16 SPI flash with TFT Display installed.So I've decided to develop my own external loader for SPI flash for storing images in my TouchGFX project. I've managed to read data from flas...

Resolved! The custom made external loader, failed to make multiple Reads, (STM32CubeProgrammer returns error)

I follow the guide to make an external loader and it works for the most part. I can erase sectors, write data. But I can only read data once. If I try make multiple Read, STM32CubeProgrammer returns error. See example below:Example:14:56:32 : Time el...

Resolved! ST-LINK_gdbserver, ability to only program internal flash?

Hi Guys,So with TouchGFX we can end up with lots of graphics data that resides in external flash.ST-LINK_gdbserver I think uses the ST Programmer to flash the elf which flashes the normal flash and the external flash.If there is a lot of data then th...

Resolved! Images are distorted when the binaries are flashed from STM32CubeProgrammer, but works fine when flashed through TouchGFX ->Run target

Images used in the screens when TouchGFx project is created displays fine when the Binaries are loaded from TouchGFX ->Run Target. When the corresponding code generated for STM32cubeIDE is built and loaded on the board using STM32CubeProgrammer using...

Why a working simulation does not work on the target.

I have an STM32469I-DISCO kit. I followed tutorial 2 in TouchGFX and tested it with the simulator and it worked fine. Then I tried to run it on the target board. The program downloaded but the screen remained blank yet TouchGFX said it was successful...
