Hi All,I am reading data from UART via polling method. I am sending random data on UART pins and reading on terminal. in that case my program is working fine in debug mode but when try to make this work without debug mode or I can say normal program ...
I have STM32H750 100pin chip and STLINK-V3MINI. Pin 9 of mini 14 pin connector has no obvious place on the chip. There is already a JTCK/SWCLK signal between 6/14 and PA14/STM32H. I am using AN4938 table 6 and UM2502 also table 6 to connect debug pin...
I have a board that is STM32H747I-DISCO which was bricked due to the power supply settings improperly set (Set to LDO when it shouldve been SMPS) in the code.The documentation say to boot with BOOT0 pin set in order to restore the working image, I do...
Hello Community. STM32F030R8T6 seems to be unavailable. This is a huge problem. Does it exist a pin to pin an alternative (also on other families (STM32F1, F2, f3...).STM32F030RC is NOT a solution since it appears not to be available too. In any case...
Hi, I made a tool to flash/debug e.g. STmicro's (EBlink) that uses direct writing instead of external flash loaders. I noticed that the current speed step of the STlinkV3 goes from 8MHz directly to 24MHz with no jtag/swd speed settings in between. ...
Hello together, I'd like to know which ST Link is the one to work with a STM32G070.We have some old V2 ones which will not be updated because of the compatibility to old projects. Is it better to use the V3 or the latest V2? Thanks a lot.
Hello, Got a stm32H750B discovery board and it kills me as i don't fully understand.I managed to understand a bit with the help of clive, as right now when i try to connect with STLINk v2 on the SWD connection i get a STM32F72X chip recognised (not ...
I want to quickly verify the SWD debug interface of my new H7 MCU. These is no firmware can be downloaded to MCU so that I need to just verify the MCU and debug can work. It is pure hardware test.
Hello,I am developing the PCB for the STM32L433 board, I come across a question about the 32kHz crystal. I will use the ABS07-LR-32.768KHz (CL = 6pF), it is among those recommended by the uC datasheet.My question is, since the capacity of the crystal...
Can some one guild me to get Schematic of STM32H745XI DISCOVERY KIT .We need hardware Schematic of STM32H745XI DISCOVERY KIT to understand EMMC connection and QUAD SPI NOR flash connectionbut there is no systematic provided for the same https://www.s...
