Part Number: TMS320C6678
Hi team,
Here's an issue from the customer may need your help:
Two DSP reference clocks are 156.25 MHz, inkspeed is 6.25G, Input Termination=111b(DC coupled systems).
The 0 core of DSP1 runs to while(0===(gpHyperLinkRegs-> STS&CSL_VUSR_STS_link_mask)); , the 1 core of DSP0 runs to wait_Hyperlink_PLL_Lock();
//////////////////////////////////////////////////////////////////////
Wait_Hyperlink_PLL_Lock();
/*---------wait for link status OK-------------*/
while(0==(gpHyperLinkRegs->STS&CSL_VUSR_STS_LINK_MASK));
while(gpHyperLinkRegs->STS&CSL_VUSR_STS_SERIAL_HALT_MASK);
while(gpHyperLinkRegs->STS&CSL_VUSR_STS_PLL_UNLOCK_MASK);
while(0==(gpHyperLinkRegs->LINK_STS&CSL_VUSR_LINK_STS_RX_ONE_ID_MASK));
/////////////////////////////////////////////////////////////////////
It's found that the DSP0 1 core register values are all 0:

While the 0 core of DSP1 has a register value as follows:

What's the possible reason for why link doesn't work? Could you help check it? Thanks.
Best Regards,
