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...
According to AN4661 "Getting started with STM32F7 Series MCU hardware development ":"When the voltage regulator is enabled, VCAP1 and VCAP2 pins must be connected to 2*2.2 μF low ESR < 2 Ω ceramic capacitor. In the STM32F7x2Rx devices, only the VCAP1...
Hi folks,I am trying to set the RDP option bytes to have my code in flash read-protected. Instead of using ST-Link Utility, I want to set the read-out protection in the code itself (specifically, inside a self-designed bootloader). For this purpose, ...
Hello,I am working with STM32F413H discovery board so far, it was working fine with inbuilt debugger but this reference board raising error like "Error in initializing ST-LINK error" while flashing.So is it necessary to reset using cube programmer if...
My project compiles with no errors and no warnings. Debug configuration generates a .bin, but Release configuration will only generate a .elf, that STLink will not use under Windows. I have tried selecting C/C++ Build ->Settings ->Tool Settings ->M...
