Hello, I have started working on ARM CORTEX MO MCU (AC30M1464LBN) using the ABOV starter Kit. Firstly, I have downloaded LED BLINKY source code into the starter kit, it worked well and good. Next, the same code I have configured for RTOS using Keil RTX option in uvision5 IDE. The code got compiled and I successfully downloaded that program into the kit. But, board didn't worked properly as the source code. Well, this is not the problem. The problem started after this. After that RTOS program I cannot download or erase the program into the kit.So, I am getting "Error: Flash Download failed - Target DLL has been cancelled Flash Load finished". Even though selecting the "CMSIS-DAP Debugger" in Debug option, I am getting the error.One more error to highlight the problem is that, I am also getting in SW Device is DLL Error and in device manager I can see exclamatory mark at the driver side. I think RTOS program created some problem. Please can anyone help me through this. I am completely stuck.
So have you contacted ABOV for support with their kit?
"also 'A-LINK UART CDC driver missing' error from the laptop"
That shows that you have a fundamental problem with the kit - nothing to do with Keil.
