ST-Link v2. GDB Error

[nazmul87]

Hello All, 

I am using stm32f405rgt6 with ST-Link v2.

I built the minimum circuit searching from internet. 

When i am trying to upload the code, it gives me following.

Can any body help me on this.

Hello @nazmul87 and welcome to the community;

Do you still have this problem to solve?

Have you checked the USB cable or tried another USB port? Have you tried STM32CubeProgrammer?

I recommend you to look at this FAQ which may help you to solve the issue.

I think Getting started with STM32F4xxxx MCU hardware development application note can help you to develop your own board. This application note is intended for system designers who require an overview of the hardware implementation of the development board, with focus on features like
• Power supply
• Package selection
• Clock management
• Reset control
• Boot mode settings
• Debug management

I hope this help you.

Thank you.
