QUAD SPI MT25QL128A with stm32H750Ibt6 controller.
Hello all,Currently i'm working over STM32H750IBT6 Controller with QUAD SPI MT25QL128A External flash. The objective is to boot from internal flash address which is 0x08000000 and jump to external flash address, as the internal flash memory is quite ...
QSPI NOR flash on top STM32, may I know if QSPI NOR flash can work half as memory map and half as block mode ?
A file system runs on half of NOR flash (64M) as raw block mode, and the memory map mode (32M) run other half of NOR flash (32M run code as XIP). These two modes don't need work same time.May I know if that is possible?Thanks a lot for advise.
How can I use external flash and ram with X-Cube-AI on the STMH747XI-DISCO board?
I want to run some AI models on the STMH747XI-DISCO board that are too large for the onboard flash and ram. I have absolutely no problem setting up the project with Cube AI and getting the model loaded. In the network Advanced Settings, I have extern...
Iam using STM32L412 nucleo board. To achieve low power consumption Iam using standBy mode and RTC Wakeup. On wakeup I found that the data is not retained .
Iam using STM32CUBEIDE for setting up the project. While refereing I have found some articles stating that standby mode default sram contents are lost and we need to use the backup mechanism also I found a reference like (http://5.9.10.113/62624874/s...
UART with Circular DMA mode polling - NDTR gives wrong (full) value on wrap in circular buffer
Hello,I'm experimenting with DMA, following a lot of examples. I'm reading DMA counter to determine if there are any new bytes received in circular buffer. I use CubeIDE on STM32f779. I have following code :void HAL_UART_RxCpltCallback(UART_HandleTyp...
Resolved! Incorrect 16-Bit HAL SPI Result in Loop/Reset
Using the stm32h745I-disco board and there seems to be an issue using HAL_SPI_Transmit in a loop. I get the correct SPI data for the initial transmission, but after that the 16-bit value is all over the place. Only 0xFFFF remains the same over the lo...
SPI2 not working on NUCLEO-L452RE
HelloI've got an issue to send byte though SPI2 on the STM32L452.SPI1 and SPI3 works without any issue. But nothing on the SPI2.The code was generated from STM32CubeMX.Here is the SPI2 init :static void MX_SPI2_Init(void) { /* USER CODE BEGIN SP...
spi1 bus with multiple slave is possible?
Mostly our spi will use these 3 signals (SCK, MISO, NSS (CS) ) in master rx only mode. where multiple slave are connected to SPI and each will have a dedicated CS in star topology as shown above. How to select this NSS/CS pin for individual slave, ca...
