Is there a UART library in C for the ADSP-BF537 or BF537 Ez Kit Lite? So far I have seen the uartlib.asm in the sample programs. Also in the EE-347, there is a provided UART library in C but for some reason I can't build the sample project it's in. I also tried using the said uart library with its dependencies in my project but it still doesn't work. Does anyone have another UART library in C which I may use? I'm using Visual DSP 5.0. Thank you!
Yes that was the reason why I couldn't build the project. The "ADSP-BF537_FAMILY-UART_basiccrt.s" was successfully generated, however, upon rebuilding the project, this error came out:
----------------Configuration: ADSP-BF537_FAMILY-UART - Debug----------------
".\..\Common Code\init_platform.h", line 90: cc0035: fatal error: #error
directive: target not supported
#error target not supported
I tried commenting out that portion, but then a new error says that it's missing the services_types.h library. I also tried making a new project with the same header files and source files as the ADSP-BF537_FAMILY-UART and upon build, this error occured:
----------------Configuration: UART_test - Debug----------------
cc1458: Fatal error: could not obtain license
1 catastrophic error detected in the compilation of ".\ADSP-BF534-UART.c".
cc3089: fatal error: Compilation failed

Build was unsuccessful.
I am using Visual DSP++ 5.0 (Product Version: 22.214.171.124 and IDDE Version: 126.96.36.199). Its license is an Evaluation license, Demo - Full, expiring in a couple of days. Is this the reason why I'm missing some libraries and licenses and therefore can't build the project?
Also, i have checked the UART-specific Device Driver documentation at "...\Blackfin\docs\drivers\uart\", but it doesn't state whether to configure it for UART0 or UART1. Does this only work for one of the two (UART0 perhaps)?
