Unable to enter Debugging mode in Rumba32 with (Platformio + STlink-v3 + Marlin 2.0)

[amithbg]

Hello All!!

I am currently building a 3D printer with a Rumba32 board and using Marlin 2.0 firmware. After following your tutorials and few issue comments, I am now able to flash the board with ST-LINK-V3 debugger in SWD mode. Unfortunately, I am running into an error when I enter the debugging mode. I have attached the error log below, please guide me through the further steps that can help me fix this.

I made these changes to both platform.ini and stm32f4.ini to successfully flash rumba32 using debugger: upload_port = COM4 upload_protocol = stlink monitor_speed = 500000 debug_tool = stlink debug_init_break = tbreak setup debug_port = COM4

I am looking forward to your responses and valuable suggestions.

Thanks & Regards, Amith
