Using the STM32L4S5 Discovery Kit board (B-L4S5I-IOT01A), I have gone through the sample CMAKE getting started projects from Microsoft as well as tested the STM32Cube IDE sample projects. Both packages appear to be developed by ST. The CMKAKE version...
I am implementing ethernet on bare metal STM32F746-DISCO board. I configured rmii, set the PHY interface and "happily" receiving packaged on the DMA buffer. Problem is that sending doesnt work. Before setting TX descriptor for first package, DMA_SR f...
I designed a custom board with FT4232 and EWB-STERLING MODULE.the module contains stm32f4x MCU, I struggled how to programming the MCU with OpenOCD and JTAG with (FT4232HI try to help with LAIRD but no one knows how to help me and refers me to ST.ple...
I need to know the timing constraints for bootloading (over UART). How long must \RESET be held low to reset? How long must BOOT0 remain high after \RESET is released? I need this for the STM32L4P5, the STM32F423, and the STM32G031. I apologize ...
Hi,our porject use TZEN =1;A custom Bootlaoder (secure app) is executed at begin and after we call a non secure Application.The non secure Application as already been tested/validated with TZEN = 0.This application use GPDAM channel 10 ro read data f...
I am using STM32F103VGT chip and custom PCB with USB, graphics LCD (FSMC mode), RTC, CRC, ADC, TIM2, TIM4 and UART3 (DMA/IRQ).When I added SDIO, one data line (poling, IRQ or DMA) and FATFS, I noticed, that after mounting, reading and writing to SD c...
Hi,in RM STM32G4 (I use Rev. 7, page 1882, Figure 648 "Transfer sequence flow for I2C master transmitter for N>255bytes":The "RELOAD=0" info in last box at "N<256" is wrong.It must instead say RELOAD=1, AUTOEND=1 (otherwise Stop bit will fire immedia...
I need to have wifi connectivity on my B-L462E-CELL1 wifi board. I am using L462_TCP_Echo_Client app as my starting point. I am using USART2 and here's my initialization code:void MX_USART2_UART_Init(void) { /* USER CODE BEGIN USART2_Init 0 */ ...
We have a project on an STM32H750 using FreeRTOS and I am trying to access an I2C device after the peripheral inits but before the FreeRTOS init and scheduler start in Main.c but I get no interrupts from the I2C port. I have checked that the interrup...
Is it possible to flash the internal memory of a blank STM32L496ZG through USB? The device has Boot0 pulled down to GND, but all the memory banks are blank, from the application note it's unclear whether the MCU executes the embedded system bootloade...
