Target is not responding, retrying.. Issues ?
Hai....., I am using STM32H743IIT6 custom Board and CubeIDE. Run the code after download it showing "Target not responding retrying......." and again try to download the same code in MCU i couldn't download, It show "Error in initializing ST-LINK device. R

I had faced with similar issue on Nucleo F103RB for debugging alternative.
I have solved with clock setting of CPU as 8MHz from 72MHz.
After this change problem has gone away.
Thus problem CPU drain increase as not matched with USB operation from PC.
So alternative way is increase power drain asserting from VIN terminal with external power supply.
Please try it.
How can I recover my STM32H7 board after facing a power configuration deadlock?
After programming my STM32H7 and performing a reset, I find that I can no longer connect to my target using STLINK. Why does this happen? How can I recover my board?Note that your STM32H7’s SMPS or LDO firmware power configuration must match with the boa

Why my STM32 doesn't start?
How to make sure the STM32 starts properly in our design? Let's look at the following aspects in more detail: 1. HW considerations 2. Start-up configuration 3. Software 4. Summary (TL;DR) 1. HW considerations Datasheet and other documentation Please always

Let's make legacy equipment connected!
(From USB Serial cable connection to bluetooth connection! )
1. This page is made for converting usb serial port to bluetooth port. So as to communicate mcu's usb serial port with smartphon.
- I have a STM32F107 + PL2303(mini usb port) embedded device.
- This is a legacy device only communicate through this mini usb cable with PC.
- So, I'd like to make communication with this legacy device through bluetooth.
- overview of converting USB serial port into bluetooth
>interfacing USB SerialPort with Bluetooth module
- How to wiring between USB-to-TTL converter and Bluetooth (BT-05 or ZS-040)
USB-to-TTL converter TX <-> TX : Bluetooth
USB-to-TTL converter RX <-> RX : Bluetooth
USB-to-TTL converter GND <-> TX : Bluetooth
USB-to-TTL converter 3.3V <-> VCC_IN: Bluetooth
