Not long ago, I used LPC1114 to make an MP3 development board. The SWD download method under the JLINK tool was perfect. But when I used LPC1114 to do another project recently, I found that when debugging in the SWD direction of the JLINK tool, the following prompts always appeared (mdk4.13). Many netizens also encountered this problem:
Keywords：LPC1114 MDK JLINK
Reference address：How to use MDK and JLINK to connect LPC1114
After continuous efforts, I finally found the reason: when I was using 4.13a, I could only set it as follows to work properly:
The settings for 4.12 are as follows:
From the above, we can see that the settings of 4.12 are commonly used, while those of 4.13 are different. So it is explained that you must pay attention to the settings when using MDK and JLINK for debugging, and the settings of different versions are different. As for why this is the case, it is unknown. By testing 4.14, it is found that the settings can be the same as those of 4.12, which seems to be a problem with 4.13.
