Hi, with the latest release of ST-Link 4.5.0 i've a problem using 'Automatic Mode'.I click 'Start' button, attach the cable to my board, and the flash is done. I detach the cable, change the board, attach the cable to new board, but nothing is done. ...
I wrote a lib to handle different routine that read/write the flash. Everything works fine.The linker file is customized with some page declarations later use to affect some variables to some flash area.I have done all the debug using the embedded ST...
st link is unable to connect with stm32f103r8 in my circuit board, while programming using keil the nrst pin becomes low when debug is applied and unable to program, but using IAR & ST link utility unable to connect to the microcontroller, board is p...
I'm currently using an STM32L4 on a custom board, trying to implement is a composite USB class that allows CDC and MSC at the same time. I am working with the STM generated classes for CSC and MSC, and have written an intermediate composite interface...
After a redesign of the PCB, STM32F401RB is not recognized by the PC when connected via USB. There is no change on the USB Connections. There are 22R resistors connected in series with the USB data lines. Is this issue related to the value of the res...
Hi Experts, I'm using STM32F407 MCU, in a bot where I have seen ESD due to (friction/movement) in the bot, and this ESD reset my MCU several time unexpectedly.So I would like to know an ESD protected reset circuit for the board any other suggestions ...
ST-LINK utility connects normally and the target reacts as expected to its Run / Halt / System Reset buttons.Clicking Run or Debug from Workbench causes the target to become unresponsive. The target recovers by subsequently reopening/connecting ST-LI...
Hello,I am designing a custom hardware for STM32L051K8U6 microcontroller but I am not getting the reference design for the mention controller. Please share the link for the design if I missed it.Thank you
Hello Team,We are evaluating 32L4R9IDISCOVERY reference design for our wearable device development.While exploring BOM we found that the AMOL OLED[MPN : IEG1120TB103GF-001] [datasheet attached] which is used in the evaluation kit is not more availabl...
Hello Team, We are evaluating 32L4R9IDISCOVERY for one of wearable device.While checking obsolescence we got to know that the Pseudo SRAM used with it i.e., IS66WVC2M16ECLL-7010BLI is facing unconfirmed lead time.As a cross reference to IS66WVC2M16E...
