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.
What is an "ABOV" ?
"I have downloaded LED BLINKY source (sic?) code into the starter kit"
Really??
You don't (usually) download source code to a Target ... ?!
ABOV is a semiconductor manufacturing company. I am using AC30M1464 microcontroller, of ABOV semiconductor company. ABOV has their own development kit also, on which I am working. Keil uvision IDE has example codes in it. It also has example codes for ABOV MCU's. I have copied "LED BLINKY" project and downloaded it into the kit. It worked well and good. The same code I have configured it with CMSIS-RTX to run the LED BLINKY on RTOS. I have written a code creating main.c and thread.c and also selected suitable drivers for the code. The software written was error free, so I downloaded that code into the development kit. Since that, I couldn't connect to the kit,neither I can download the new file into the kit, nor I can erase the program from the kit. It is showing "RDDI-DAP error" and also "A-LINK UART CDC driver missing" error from the laptop. Thanks.
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.
Get the correct/current drivers for the board. Try the Connect Under Reset option and see if the board or chip has a Boot Mode that runs ROM code instead of the user loaded application.
Yes, Thank you.
