SRIO Initialize Error withTMS320C6455

Hi,

I have a problem to initialize SRIO with TMS320C6455. I checked "TMS320C645x DSP Serial RapidIO (SRIO) User's Guide" (SPRU976E) and tried to test using "SRIO Initialization Example" in the document.

It seems no problem but I would like to set non-loopback mode. When the loopback mode is disable, the error message is displayed like below.

     COM: Application error = 'SRIO INITIALIZATION'
     COM: Source line = '863'
     COM: User Info = '0x1'

(I could find the error is occured because last bit of SPn_ERR_STAT is set "PORT_UNINITIALIZED".

I also have TMS320C6474 and tested with same way. But there was no problem in non-loopback mode.

Any idea?

Thank you.

Not sure if you got this working, looks like your post slipped through the cracks... If you are looking for known good SRIO init function for C6455, check out the DIOLib at:

http://processors.wiki.ti.com/index.php/DIO_Library

If you are not getting Port_OK, something is wrong physically in the connection between the link partners, or in the configuration where the link partners are at the same datarate or port width.
