TMS320C6678: 5 seconds wait in hyperlink example

malek alashiri

Part Number: TMS320C6678

i was reading hyperlink example in pdk_C6678_1_1_2_6 and i noticed there is 5 Seconds wait between two "Link Error check" operation. and it seem in mentioned code, only after second Link check which happens 5 seconds after first one that link consider stable.

we need to boot as fast as possible and don't want to wait for 5 second to check link errors again. the question is, is this wait necessary?

Hi,

No, that is just example code, you don't have to wait for 5 seconds to check.

thanks for your reply.

is there any suggested number (seconds or milliseconds), to wait? or can I completely ignore second "link error check" process?

Hi,

You can ignore this check. This only print out info for your diagnostics, but will not resolve the link issue.

You need to monitor the ECCErrors.sglErrCor and CCErrors.dblErrDet to see if they increase over time (they may be no-zero at the link open), especially under heavy traffic. Increasing error counters means link quality problem and may lead to link failure.
