I am using below componnet toolsMCU: STM32H7B3IIT6IDE: STM32CubeIDE Version: 1.9.0CRYSTAL: RT3215-32.768-12.5-TR ( 32.7680KHZ 12.5PF)I work with internal RTC. I will use for clock. But RTC clock behinds real clock. While the product is running, the l...
HiI wished to use my Segger J-link Pro to debug my Disco' Board, but when I connect using CN12 the Segger Spring Pin header it won't connect to the target, although the IDE and Programmer can "see" the j-Link probe. I read the board's user manual (UM...
Hi,I'm interested in hardware connection of STM32U5 and Smart card. They can be connected directly or there need to be Smartcard Interface circuit between (like ST8024)?Thanks in advance,Nenad
I just received 2 STM32L053 Discovery evaluation boards. Is there a demo preloaded on the board? What is it supposed to do? After I plugged power into USB ST-LINK, the first board cleared the display while the second did not. Then the boards do nothi...
We are using STM32F427VGT6TR, in our project. We found the MCU went to "Level1- read protection" while performing a hardware debugging. We are not able to disable level-1 and put the MCU into the Level-0. We are able to connect the MCU using STLink a...
Hello there,I have a STM32F303 chip and use ST-Link V2 to update the FW of the chip on my board.If I uses STM32 ST-LINK Utility(V4.6.0.0) to update the FW of the chip, then it's working fine:after updating FW and after power cycle, the chip on my boa...
I am trying to flash a STM32L053 Nucleo using UART pins and so far, I pull boot 0 high by adding a jumper across boot 0 and VDDI power the controller with E5V optin and connecting an external poer supply to the E5v and GNDIf I connect the USB to the ...
I'm using the Nucleo-32 on another project and have found the schematics in UM1956 helpful in certain debugging scenarios, as well as a kind of reference design to help me get started on my own board design.
i'm using the stm32u5 iot eval board BU585IIO2A and want to use USART3 on Arduino connector CN14i successfully got the PWM working on PIN7 of CN14 but i fail to get anything sent / received on UASRT3 (Pins 1 and 2 of CN14)are there any hints / sampl...
I have PCB made for STM32F103C8F46 with the attached schematic. At first I use ST-LINKV2 debugger to connect to the target. It connects successfully and able to flash the code as well. and it works well. But after some-time (like 5-10minutes) of keep...
