Hey, iam working with a STM32 L432KC with an ST-Link onboard.Iam am planning to create a PCB with the same chip and iam wondering how i could programm/debug it.I read through the Instructions and i think SWD is the right thing for me.I have a STM L45...
Hi STM Team,We are trying to flash code to STM32H745 through SWD interface. However, after multiple flashing cycles to STM, we unable to detect device in 2 or 3 boards.The below are list of the observations of that scenario.Once we give 3.3V supply t...
I can't imagine for pre-production to have to tie boot to vcc or the like as it is described on the discovery boards. Would be complicated to do this and will have to introduce additonal circuitry like a switch or rc circuit. If so can someone provid...
I am designing my own board using STM32H7 controller. I am trying to flash the code using STLink V3 mini cable(SWD) and STLink V3 cable is having Virtual com port(UART) also for communicating to the board to the Host PC. How this connection will look...
Hi folks,I'll try to keep it short. I'm working with an STM32F103xx MCU and an ST-LINK/V2 probe. I'd like to use it to program the MCU. I've been reading the ST-LINK_CLI user manual, and the STM32F10xxx programming manual. I have this question: How m...
Hi everyone. I wrote a program in assembly for stm32f407 and loaded it to mcu using uvision and stlink. The mcu works properly in debug mode( at debug state the reset pin has high voltage) but when i disconnect the usb, mcu stops (and reset pin volt...
HiI have bought two different ST-LINK/V2 devices: one has mark "EN Version" and another has "CN Version". Works only "Cn Version":Another doesnt work.Settings for connection (other settings cant make a connect to device). Vdd on MCU i measure indepen...
Is it possible to read what is sent by a UART in a serious port through the stlink?
Hi.I use a AZ3166 board.Suddenly, When I connect the board to PC by USB,USB storage doesn't appear .But, Using ST-Link utility, I can program .bin file to EMW3166 via ST-Link.Could you tell me how to get a ST-Link boot program(.bin) .I plan to progr...
GPIO_PinRemapConfig (GPIO_Remap_SWJ_Disable, ENABLE); I closed the JTAG pins on the stm32f103 processor with the command. Then when I tried to connect via the ST-LINK Utility program with the Connect-to-Target button, it did not see the processor. So...
