I am trying to erase a sector of the flash memory on my STM32H503RB. I have successfully validated that I can write to the flash, but when I attempt to erase the sector that I wrote, the contents that I wrote stay the same. I have a feeling that I ...
Hi,MasterMCU: STM32H743IIQuestion:Both FDCAN channels in the MCU are currently in use. I now intend to reset each FDCAN instance (i.e., reset all its registers) during its respective bus-off event, and then reinitialize the instance. Resetting all ...
Hello, I have implemented a sdcard socket on my board based on the STM32F411, I use SDIO & fatfs r0.15c p2, The SDIO DMA NVIC configuration is : /* DMA2_Stream3_IRQn interrupt configuration */ HAL_NVIC_SetPriority(DMA2_Stream3_IRQn, 6, 0); HAL...
Hi,I am designing a custom PCB with an STM32H723. To programm it, i bought a brandnew ST-Link v3 MINIE. CubeIDE reads the serial number of the V3 but can not connect to the target.- Target is supplied with VCC.- From the Board-to-Board-Connector afte...
I have the following flash protections requirements:1) Write protect the last sector (with start address 0x0803F800)2) Read protect the entire flash with Level 1.3) If the read protect is lowered, the data in the last sector must be unchanged.I'm per...
DK1 interface a one lane DSI display. DSI display is using SH8601A LCD driver. SH8601A only can be initialized in LP mode, not HS mode. In Mx, DSIHOST configuration, 1. Bus Turn Around Request is enabled2. Transmission commands in LP mode is confi...
Hi All, I want to build a system to sense 240 low current signals at 20kSPS at the same time using 15 ADC with 16 channels each (DDC316 by Texas Instruments, Datasheet: https://www.ti.com/lit/ds/symlink/ddc316.pdf). I intend to use something like t...
Hello all,We are trying to get into the bootloader of the NUCLEO-U5A5ZJ-Q over SPI using a STLINK-V3SET. But are having issues with connecting the V3SET in the STM32Programmer and through the CLI, which is getting this error.So far, we are seeing thi...
Hello,I have existing hardware designed using STM32G0B1VET6 microcontroller. I want to redesign this hardware to provide Ethernet interface. I am planning to use ICs like LAN9250 or KSZ8851 or ENC424J600. But all these ICs require TCP/IP stack on hos...
I Tried to flash the uart code in stm32 N657 Nucleo Board, but it is not responding, i was able to make the Leds, blink in the N6 board. Please help me out, i am using the uart example printf code in the N6 stm32 package. I tried the normal method us...
