Hey team,
I am new user to arm Keil platform, and i use keil uvision5. I have 0 errors and 0 warnings. But i can;t load the program or debug the program. The pop-up shows the error that, Error: Flash Download failed - Target DLL has been cancelled. I do all the possible changes in target utilities, the error remains same.
Note: i can't connect any device through USB. Is this is a reason for the error or not?
kindly let me know the solution with proper guidance or direction notes to solve the error.
Can you provide more detail on your setup?
Which debug adapter are you using? Is this set correctly in Target Options > Debug, and select the correct one from the 'Use' pulldown.
Then click Settings - do you see a successful connection?
Great,
I am using JLInk segger driver for debugging.
Could you pls let me know, what can i do with this.
To be cleared: I use JLINK segger application for debugging. is any external device, should i used for debugging? Kindly let me know.
According to these two screenshots, the J-Link debug adapter is not recognized by µVision. Did you really connect it to your PC and is it correctly detected as a USB device under Windows? Did you test the J-Link with the Segger tools so that you can be sure that it works?
