Can't use fscanf and fprintf commands in CCSv3.3 with EVM6474

Hi everybody!

- Issue one: I create new project and use EVM6474's tcf file to load my code to DSP. Unfortunately, when debugging, the complier shows the error "run placement fails for object ".far", show I have to change .far file from L2RAM to DDR2 to resolve this issue. However, when I run my program, I realise that both fscanf and fprintf commands are not active. Have you ever gotten this issue, please help me.

- Issue two: I use EVM6474's tcf file to connect RTDX to load file through Visual basic interface.  after already  receiving all data, I stop RTDX by using the function  RTDX_disableInput to be disable RTDX channel. Poorly, my program is continuously running, not breakpoint. Please help me resolve this issue.

Thank you very much!

    So I assume that moving the .far section to DDR2 resolved the "placement errors" and you were able to get a successful build? Regarding the fscanf/fprintf issues please refer to this wiki article for the most common reasons for these issues: http://processors.wiki.ti.com/index.php/Tips_for_using_printf

    I'm not sure I clearly understand the issue here, but RTDX is unfortunately no longer supported. But you may find some tips/debugging suggestions by searching the forum or the RTDX documentation in CCS.
