STM32 MCUs Embedded software

Is it possible to use an external SRAM QSPI chip with the STM32G4 to expand the 128KB of SRAM?

The hope is to use the STM32G4 to run FreeRTOS. Doesn't seem like the current implementation will fit within 128KB, but I don't have enough pins available to use the FSMC. Is there any way to use something like the apmemory IoT RAM (can't post the li...

how to transfer files from stm32 board as mass storage class in device mode to pc.

hello,I able to see the stm32 RAM as storage in pc. I want to transfer the files and buffer data to pc from stm32 RAM as storage. int8_t STORAGE_Read_FS(uint8_t lun, uint8_t *buf, uint32_t blk_addr, uint16_t blk_len){ /* USER CODE BEGIN 6 */ memcpy(...

task is not running after hard reset in freertos

hi,I make bootloader to switch the code between two bank starting at address 0x08000000.and two application starting at 0x08020000 and 0x08100000 respectively, when I individual run the code it work fine, but when I hard reset the code, it goes to bo...

ThreadX on STM32: RAM nearly filled up

I'm currently starting to use ThreadX / AzureRTOS on a STM32 Nucleo-H723ZG (STM32H723ZG MCU).I noticed that when loading the Nx_TCP_Echo_Server / Nx_TCP_Echo_Client projects from CubeMX, the RAM gets filled up pretty much to the top, which makes me w...

STM32L4R9 - SD-Card (FAT FS, SPI) as mass storage device not detected

Hi STM32-Community,I'm currently trying to get a micro sd-card as a mass storage device to function. Writing/Reading from the SD-Card works, aswell as configuring the STM32L4R's RAM as a mass storage device, but combining both kind of failed miserabl...

How to share variable between bootloader and application without overwriting

Good morning,I have a problem sharing a variable between bootloader and application into my STM32F303ret6 uC. I need to write a shared variable to tell the bootloader that it has to wait for new firmware.I read many posts which suggest to declare a v...

Mount FATFS on STM32H735G-DK's external HyperRam chip

Hi,​I'm interested in mounting a dual drive fatfs on the ​STM32H735G-DK's external memory chips connected to the octospi interface (512M NOR flash MX25LM51245GXDI00, 128M HyperRam S70KL1281DABHI023) I'm not familiar with HyperRam and I'm wondering is...

How to utilize full 128KBytes of SRAM in STM32L476

Hi,I am currently working on a resource-hungry project which requires a lot of memory for storing various buffers and RTOS threads stacks and objects. We are using the STM32L476 controller with Keil uVersion 5.34 IDE and Keil RTX5 as RTOS (CMSISv2) f...
