First time using Keil uVision v5.21 and build my image for QN9080B - ARM-Cortex M4. Trying to load my image with J-Link mini. Having "Error: Flash Download failed - Target DLL has been cancelled" all the time. I looked over those old discussions. Still a problem.
So please help.
Thanks,
Sam
So can you program successfully using Segger utilities?
ie, is this a fundamental problem with your hardware, or something specific to Keil ?
Thank you for helping. After putting some jumpers on my board, J-Link can see the board. I was able to erase the flash. But at the end of programming. it says "Flash Load finished at 15:42:10 Full Chip Erase Done. Programming Failed! Error: Flash Download failed - "Cortex-M4" Flash Load finished at 15:53:16"
