Hi,Can someone clarify why some examples of boot to QSPI change the SCB->VTOR register in JumpApp function :SCB->VTOR = (uint32_t)Application_vector;JumpToApp = (pFunction) (*(__IO uint32_t *)(Application_vector + 4u));__set_MSP(*(__IO uint32_t*) App...

Hi,On a custom board using STM32H730ZB, I try to use QUAD SPI flash memory.Here is the CubeMX config :In MX_OCTOSPI1_Init function, I break on HAL_SPI_INIT functionThis function come from pack STM32H7 version 1.11.2In line #415 of stm32h7xx_hal_ospi....

I have a custom board with a STM32H730ZBI use a LCD 1024x600 controlled by LTDC.Here is the pinout :here is the config :When executing code :I break just after the HAL_LTDC_INIT function.I should have a white screen (R=255, G=255, B=255)But I have a ...

Hi, I create a new project with STM32CubeIde 1.15.1 (but same with 1.10.1)I add SDRAM 1 - BANK 1When I debug this project, after HAL_SDRAM_Init function in MX_FMC_Init(), I can wath the memory in MEMORY BROWSER at address 0x60000000.But on reference ...

Hi,Does someone have a suggestion to create a range slider with touchGFX like this Thanks

You all seem to prefer changing VTOR in the app.And yet, all the examples in the ST CUBE repository that I found do the opposite. Do you know why ? @Pavel A. propose to copy the vector table in RAM and update the VTOR after.Does someone have an exa...

Hi, That is interesting !ST examples do not do this (what I see).Does it means :1. I configure QSPI on mapped memory, in LOADER2. __Disable_IRQ() in LOADER3. Jump to the APPLICATION (in QSPI 0x90000000), in LOADER4. Copy the interrupt vector of the A...

Hi,Does it mean you also recommend to change VTOR in APPLICATION SystemInit function ?For the QSPI configuration, this is what I did : Configuration and mapped mode is only set up in LOADER.

Hi,OK, so in your opinion, you recommend to set new vector table in APPLICATION firmware in SystemInit function.You write : - Call jump function (disable interrupts)If I disable interrupt with __disable_irq() in BOOT firmware, shoud I enable it in AP...
