STM32H7B3-Discovery Kit using external flash with Touch GFX projects (having trouble)
Hello Touch GFX Guys!
Hardware: STM32H7B3I-Discovery Kit
Software: ST32IDE/ TouchGFX4.16
Using STM32CubeIDE build Touch GDX template project.
then using Touch GFX build simple "Hello world" application
message is appearing on LCD screen and everything seems fine.
Next step decided to enable external QSPI Flash.
- Using Touch GFX build template project.
- from project above copy and paste QSPI flash settings through cubeMX (hardware settings)
- added to my project desired dependencies (mx25lm51245 drivers, and stm32h7b3i_discovery_ospi c/h and all desired files) to successfully compile project.
- project compiles without warning or errors

While exanimating code, I noticed follow statement, what havent seen before with STM32 projects:
sOspiManagerCfg.IOLowPort = HAL_OSPIM_IOPORT_1_HIGH;
if (HAL_OSPIM_Config(&hospi1, &sOspiManagerCfg, HAL_OSPI_TIMEOUT_DEFAULT_VALUE) != HAL_OK)
{
Error_Handler();
}This portion is autogenerated and not sure how it will affect TouchGFX applications. Also, I haven't seen this statement in application build purely using touchGFX .
Question:
From code snippets above can you please advise if there is anything I do wrong or miss anything to while initializing external QSPI? Can you please also provide any suggestions recommendations what would be accurate way of adding external QSPI
Please advise at your earliest convenience
Thank you for your help and support.
Regards,
I
