I have installed uVision V5.27.1.0 and use a pro eval licence right now. I downloaded nRF5_SDK files for my nRF52840 and imported the file from the sdk to uvision. I think that I have the correct flash debugger and packs. Whenever I tried to debug my project, it always tells me that "Error: flash download failed - Could not load file".
When I tried to build the target anyway, it gave me lots of errors, and I think all of them said that:
Error: C9555E: Failed to check out a license.
But I do have a pro eval license for 7 days. When I tried to switch to segger embedded studio, it still gives me an error which says:
Error starting process $(KEIL_TOOLKIT_DIR)/ARMCLANG/bin/armasm.
I guess that it still has something to do with my keil uvision licence? Can anyone please help me figure it out? Thank you so very much in advance. Best, Xuewei
