Hello!I am running a FreeRTOS TCP Echo Server example on a Arm Virtual Hardware target. The echo part works perfectly, however, I would like to print out the amount of ticks it took to run the client echo from xTaskGetTickCount() in the telnet terminal that the virtual target is hosted on but the printf() does not seem to print anything in my case when the echo is done. The Client part is ran on the Ubuntu Host as a python script. From the information that I've gathered I have to do some sort of retargeting to utilize printf() properly to be able to print in the telnet terminal. I found this GetStarted example https://github.com/ARM-software/AVH-GetStarted/blob/main/basic/main.c where they managed to use printf()'s in their main function and I'm wondering how I can do the same for my project. I've tried to follow this example (https://www.keil.com/pack/doc/compiler/RetargetIO/html/Retarget_Examples_UART.html) without any success. Below I've included the project example that could be downloaded from MCUXpresso but I'm running it on Keil Uvision. The path to the project file is tcpecho\boards\frdmk64f\lwip_examples\lwip_tcpecho\freertos\mdk. The printf() are in the tcpecho.c file which is located in lwip/contrib/apps/tcpecho from line 62-94.
I don't have a "Native Driver" under my Software Component in the Manage Run-Time Environment pane. As I mentioned in the update the CMSIS Pack that seems to break my project is the USART (API) one under CMSIS Driver or is it because I don't have the CMSIS Packs for Native Driver?
The errors and warnings that are shown in the previous screenshot only appears after enabling the USART (API) CMSIS Pack.
