matlab ccs

Hello,

I am trying to set up a Matlab Code Composer link without using DSP BIOS in CCS 3.1 for a C64xx target application: my project is running in simulation mode and what I see from the RTDX analysis tool is that incoming data from Matlab is detected by CCS (the channel viewer XFR count increases every time I send a sample from Matlab) but the RTDX_readNB() does not recognize that incoming data are present.
I guess the problem is in the configuration of the IRQ 3 (HWI_RESERVED1) servicing routine: in a DSP/BIOS application the Rtdx_Poll() function is automatically set as ISR for that IRQ and the link works fine, but currently I want to avoid using DSP/BIOS and I don't know how to configure the ISR to trigger the RTDX_read() or RTDX_readNB() when the data are sent to CCS by matlab.
On TI web site I found several application notes about RTDX but I did not find any useful information about my problem.
Any help will be appreciated, thanks.
