What should I use to hold the boot?

Can you tell me what the boot file is?
I would appreciate it if you could let me know.

I found the cause. (Additional circuit diagram) url: https://drive.google.com/file/d/1sUG4Njh6N8fxbmLm5A1JxwvhqjxqI6ch/view?usp=sharing - MR1: Shunt resistance - L4,L5: Bead resistance (0 ohm~1 ohm) - Directly connected to ADC to measure current. After removing L4 and L5, the problem disappeared. It...

‘MCU basic current’ increases after PWM operation. - core: https://github.com/rogerclarkmelbourne/Arduino_STM32 1. If there is no operation, the total current of 0.07A flows. 2. Turn on PWM - (source code)pinMode(PA6, PWM); pwmWrite(PA6, 5000); 3. Turn off PWM - (source code)pinMode(PA6, PWM); pwmWr...

Thank you for your interest.


1. It works well via Serial (UART).
2. The 'CM1107' board is capable of UART communication and I2C communication.
- If 'CM1107 R/T' is 0VDC, it operates through I2C.
3. It does not work when communicating via I2C.

Thank you for your kind explanation.

thank you so much. You are an angel.
