Resolved! ST-Link V3 Set is not detecting the target MCU (STM32F103C8T6) and also no voltage to power the MCU is coming out of SWD line.
have tried with STLink V2 and it's works fine. In the manual of ST-Link V3 they are not specifying any particular jumper settings for SWD. With a multimeter I cannot detect Vcc of 3.3V between the VCC and GND of SWD pins. Please find the below pictur...
ST-LINK V2.J32.S7 Firmware ??
Hello.We are working on a project that uses STM32H747 dual-core MCU.Debugging does not work well when downloading to the latest version.So I'm looking for the V2.J32.S7 firmware that I used before.Currently, the downloadable version is J36 or later.I...
Resolved! PCB: How to wire two SDRAM ICs to STM32F7?
Hello,The STM32F7 supports up to two external SDRAM ICs, where both SDRAM ICs basically share the same set of pins. Given all the restrictions on creating traces between STM32 and SDRAM (different layers, same length, same number of vias, ...), how...
Resolved! What is the difference between ST-LINK and JTAG?
I read on the intenet that they both are used to debug the IC.But how they differ?thanks
Is it possible to use STLink-V3 mini for serial interface?
Using the EVALKIT-Robot-1 which is based on STSPIN32F0A. I am using the STLink-V3-mini rather than the RS485. I want to know if it is possible to establish serial communication through UART with the STLink V3.
How to use the STLINK of a nucleo-32 to program another STM32?
Hey everyone,Nucleo-64 and Nucleo-144 boards have their STLINK clearly appart, and many ressources over the web for using these to program STM32 µC on a custom board.Is it possible to do so with a nucleo-32 (nano format)? Are there ST documentations ...
STM32F401: Voltage dependence of RAM
Hello,I am developing a bootloader that is entirely executed from RAM. If I run the code from a Nuceleo board the MCU is supplied with 3.3V, program executed fine. If i go to target hardware (which runs on 2.5V!!), the cycle speed is reduced by ~14%....
Problem configuring higher clock speeds for custom board using STM32F446RE with blinky code.
So i have been stuck on this problem for a while and I desperately need some help understanding what could be wrong. I am using STM32CubeIDE v1.8.0 and a NUCLEO STM32F446RE board to test some basic code that blinks an LED. This works absolutely fine....
