I have just recently started learning K64F and having a bit of an issue with establishing a serial communication channel between my board and Termite 3.3 on my Windows 10 machine.
I followed this guide on how to use AsynchroSerial with Shell but no data comes through. My board runs FreeRTOS kernel and below is a few lines of code that I am trying to run within the main():
CLS1_SendStr("Hello World!\r\n", CLS1_GetStdio()->stdOut);
I've set Shell (CLS1) Default Serial to "Enabled" with AsynchroSerial (serial template) as console interface option.
Inside AsynchroSerial I set Channel to UART0, RxD to UART1_RX_TGTMCU and TxD to UART1_TX_TGTMCU. BaudRate is set to 38400, no parity, 1 stop bit, width 8 bits. Same set of configurations is used in Termite 3.3.
After connecting the board to my PC via USB and running using debug configuration (GDB SEGGAR J-Link Debugging), the LED blink, but no data shows up on my Termite 3.3 terminal if I enable interrupts in AsynchroSerial component. However, disabling interrupts causes it to suddenly start working again...
Any thoughts on what could be an issue?
Thank you for your help!
