stlink_v2.1 (with swo interface) (tested)

Overview

1. Briefly describe
ST-link V2.1, which has a virtual serial port function and can complete program downloading and serial port debugging.
About ST-link V2.1 and ST-link V2: Functionally, V2.1 has more virtual serial port functions than V2. The firmware is larger than V2, and a 128KB capacity chip needs to be used.
2. Debugging steps:
Board soldering starts with the chip, using a solder paste hot air gun, and all the SMD components on the bottom layer can be attached (USBA and pin header (JTAG interface) shown in the picture) It must be the last and last welding)
Check the short circuit before powering on (use a multimeter)
3. ICP burning
1. Open the STM32 ST-LINK Utility, connect the female end of the DuPont line to the STlink module (position shown in the picture), and connect the male end to the board. Then plug the STlink module into the computer.

2. Click the icon button to connect to the burner

3. Import the firmware in the attachment and burn it

4. Update the firmware and

click Device Connect

5. Re-plug and unplug the board, a USB flash drive is displayed

The STM32 RTC is powered by a backup battery. When the main power is cut off, how can the RTC time be reset to 23:59:59?
Originally, the program resets the time to 23:59:59. If it cannot be reset, the boot time must exceed 24 hours. What should I do? ? :puzzle:
