Hello All,
I was trying the basic Led pin example that is on you tube and tried to replicate the same thing in STM32 747 board. I was able to successfully start the debug for CM7 core. I get Download verified successfully. But when I start the CM4 core, I get his from the console
Starting server with the following options:

Exit.
I tried all this options.
1. Restarted the PC, didn't work
2. Shutdown and waited some time, still didn't work.
3. changed the port number. No luck.
4. Tried on Mac laptop still no success. This tells me it has somethings to with the hardware.
5. I re flashed the chip using STcubemx, still no luck.
6. I triple checked the STM32 Debugger settings from the youtube still I cant seem to find what it can be.
Do you think there is a possibility that CM4 chip is not working? or let me know if you guys have any other solutions.
