Hi all,We want to make an application where users can update their devices. We want to rollback if the update failed. For this, we initially took a dual boot bank MCU, the STM32L471RG. But after being busy building a bootloader for it, I don't know i...
hello, I use STM32CubeIDE 1.16.0 and working on a custom bootloader to jump to application at address 0x08100000, here're the jump code below: void jump_to_application(uint32_t flash_address) { void (*app_reset_handler)(void); uint32_t main_st...
Hi Guys, I'm working on a personal project. I have experience with the use of STM Nucleo and this time I don't know how to get out of my problem. Previously I have already used the UART peripheral in the same way that I am using it now, but now it ha...
NUCLEO-G474REMy design uses two timers, one in master mode(TIM20) and one in slave mode(TIM1).To have the master timer generate an update signal in the trigger output, I set its TRGO event selection as "Update Event". the CR2 value 0x200020 confirms ...
Hi, I tried to set up and use HPDMA with ADC on my Nucleo-H7S3L8,but I have some questions about how to use it.I could not find documentation on using HPDMA with STM32 MCU, only for GPDMA.I found an HPDMA example for the Nucleo-H7S3L8 (ADC_SingleConv...
The hardware is configured, initialization passes (fails if no card is inserted).The card is 8GB micro SD formatted on Windows with exFAT, contains 1 file "test.txt" with content "HELLO".The exFAT option is enabled for the FATFS.Here's my code:FATFS ...
Hello there!It would be really great if someone can look into this.I even tested it by reading the state of the pin and the MCU detected when the button was pressed, however when I set it up to use EXTI, its not detecting the interrupt. Could there b...
Over the last couple of years it appears that ST pivoted towards Azure RTOS / ThreadX as the default RTOS for newer STM32s like the STM32U5. This seems in part to be because of the more cohesive set of packages like USBX, FileX, etc. on top of the b...
Is it possible to disable a specific GPIO interrupt in my code and re-enable it after some time. HAL_NVIC_DisableIRQ(EXTI4_15_IRQn) this function will help but this will disable all the GPIO pins connected to that particular EXTI line. Any other poss...
Hello, I am attempting to use an STM32U545 nucleo board with an external SD card shield from Adafruithttps://www.adafruit.com/product/4682However, each time I attempt to initialize the SDMMC peripheral, the call to HAL_SD_Init fails with a DTIMEOUT e...
