Hi everyone, I am using STM32F429IGTx with ETH/FMC and many other peripherals to construct a control board. There is a special interface that I need to use TIM1/DMA2 driven GPIOs for communicating with another board that need 12 pins. Since FMC and ...
I was gonna make a project that can map USB MSC to an eMMC or external NAND Flash memory. but my knowledge of FSMC and SDIO is not enough and also I haven't worked with USB peripheral.my choice of MCU is STM32F407IGT6.can you help me find good resour...
Hi Team,Basing on the lastest "STM32F4xx_StdPeriph_Driver" to Read SPI data and then write into external FSMC(8bit) device in the PWM interrupt like following .//--------------------------------------------------------------------------------------...
Hallo everyone,I have set up Segger Ozone with a Segger J-Trace to initialize the uC. When connecting to the debuggee the clock configuration, the gpio config as well as the FMC configuration is done. After that OZone loads the programm to the extern...
Supposed I am using external memory via an 16 bit address / 8 bit data bus with FSMC (STM32F714). An RTOS is running.Is access to this memory atomic (in the sense of thread safety) when I read/write 32 bit wide data? The consideration is, for instanc...
Hello ST team,I use STM32CubeF4 1.25.0in SystemInit_ExtMemCtl() of system_stm32f4xx.ctmpreg is not initialized between each while loop, so tmpreg is 0 and the FMC_Bank status is not read tmpreg = 0xFFFF; << is missing while((tmpreg != 0) && (timeout-...
cubeMX : 5.6.1cubeIDE : 1.3.1Code Lib Version : STM32Cube_FW_F1_V1.8.0I implemented ili9341 lcd as fsmc and found the following problem.the problem is that when calling HAL_SRAM_Write_16b, it writes data once more.I attach the measured fsmc wavef...
While debugging my FMC interface I came across what look like errors to me in logic / arithmetic in the stm32f7xx_ll_fmc file.Here are the two functions of interest to me:/** * @brief Initialize the FMC_NORSRAM device according to the specified ...
Dear allDuring nand flash erase, uart interrupt doesn't work properly. (same SysTick_Handler)Let me know why this is happening.nand flash erase source :for(Addr.Plane=0;Addr.Plane<2;Addr.Plane++){ for(Addr.Block=0;Addr.Block<2048;Addr.Block++) { HAL...
Hello,We access FMC PSRAM in 32-bits.We noticed that although the access was expected to be in 32-bits (using HAL_SRAM_Read_32b) , CS signal is actually asserted for long of 64-bits!Is there anything which can explain why the CS is twice the time of ...
