RT1176 flash error.

kamleshv — Sat, 27 Dec 2025 07:03:26 GMT

I am working on a custom board developed based on RT1176 and using multilink universal debugger.

Please explain the following error and also how do i resolve it?

I have 2 problems.

1. when i try to debug my project it give following error with the popup message as attached in image file.

"P&E Semihosting Console

Connection closed by the GDB server."

2. when i try to flash the axf file directly it gives the error msg as attached in text file.

I can debug any other example from SDK like uart etc successfully.

The project is quite complex with multiple GUI Screens in lvgl. I have observed that when the

GUI project is small it works but as I add more GUI elements the problem starts.

Does flashing and debugging any way related to bin size?

Please find the build output also in the attached file.

Thankyou.

Hope you are doing well!

Based on some community experience, this issue is generally caused by problems with the debugger driver or hardware connections. Please try updating or replacing the connection cable. https://www.pemicro.com/forums/forum_topic.cfm?forum_id=9&forum_topic_id=8710
