I have a custom board running at a custom speed (SYSCLK). I was trying to print via UART to a TeraTerm console but am unable to. I know the UART traces and setup from a hardware standpoint is correct because I was able to create a project and generate output via writes to the requisite registers.
When I attempt to print the generic "Welcome to CodeWarrior!" prompt (via a bareboard example project), however, it does not print.
I imported the T4240QDS_aeabi_64bit_serial project, set the system clock variable to 128, and removed the case and QIXIS statements from the duart_config.c file. I built the file and copied the UART1_T4240QDS.aeabi.UC.64bit.a file into my other project. After building the project, I am still unable to generate output on the UART lines.
Is there a step I'm missing?
Do you really use 64-bit Build Tools Architecture?
I believe that in the discussed case it is more reasonable to import the "T4240RDB_aeabi_64bit_serial" and just modify the 'systemClock'.
What is the SYSCLK frequency?
What is the RCW source? What is the RCW[UART_BASE] value?
I'm pretty sure I set up the project to use 64-bit Build Tools Architecture. The main reason why I chose that aeabi serial project was because, in the project I'm attempting to print to TeraTerm in, it has the UART1_T4240QDS.aeabi.UC.64bit.a file in its Lib folder.
I tried modifying just the systemClock to no avail. That's when I started stripping out extraneous code from the duart_config.c file
The SYSCLK frequency is 128MHz.
The RCW source is i2c extended.
The RCW[UART_BASE] value is 0b100.
