Hello,in the STM32F7 it is possible to enable instruction prefetch and in the same time disable ICache. Then I suppose that the prefetching does not put the prefetched instruction in cache. Is it correct?Thank you
Hi!I would like to know if there is a way to handle "automaticaly" a transmit then receive transfert using SPI and DMA ?I think using linked list should be possible, but i don't know how to configure that.. -Create a single linked list (only 1 GPDMA...
How to perform SPI communication within a board (master and slave)We are trying to loop back SPI communication within the board, and perform transmission by the slave and reception by the master on one board.The master's SPI CLK is connected to the s...
So I tried upgrading the firmware. I first downloaded the STM32CubeProgrammer, linux version, on the my computer. Then I got the device into DFU mode as per instructions and attempted to flash the new firmware using the STMCubeProgrammer software. Af...
Hello, ST experts STM32U595VJT6 is used on the design. The OTG part of MCU works well on USB device mode. And it functions as USB flash disk. But when I check the logical level from OTG device status register(address offset is 0x808), there is somet...
Hello, I have a stm42f411 with SDIO 4B configured and working properly. the SDIO conf is the following: hsd.Instance = SDIO; hsd.Init.ClockEdge = SDIO_CLOCK_EDGE_RISING; hsd.Init.ClockBypass = SDIO_CLOCK_BYPASS_DISABLE; hsd.Init.ClockPowerSave ...
Hello everyone,I'm using Board NUCLEO-U031R8 for testing now.I have an old FreeRTOS project designed for a power-saving application, and I am preparing to migrate it to a new IC STM32U031 series MCU.In the old project, setting configUSE_TICKLESS_IDLE...
Hello everyone,I'm using Board NUCLEO-U031R8 for testing now, and I started with cubeMX and initial component below:System Clock configure to HSI (16MHz)FreeRTOS with USE_TICKLESS_IDLE as 1 (built in functionality enabled), and auto generated two fun...
Hello,We are developing an industrial application based on STM32H7 (STM32H723ZGTx) and we are using NXP "TJA1101B" for PHY.It is connected to STM32H7 using RMII interface. We took hardware reference from "TJA1100 Customer Evaluation Board" schematic....
Hi,I used a Nucleo-F303RE board as template for my own hardware. Timers and clockfrequency are running fine on the NUCLEO but they are slow by factor 9 on my own hardware. USARTs are running on the exspected baudrate. Factor 9 gives a hint to the PLL...
