DVRRDK Overflow Problem with HDVPSS SC4

Iris Zhou

we are working on DVRRDK03_00_01_03,the platform is dm814x,we find a overflow problem,we run a simple link chain

like captureLink(VIP1_PORTA)->swmsLink(SC4)->displayLink, when VIP1 overflow occurs,the HDVPSS turn to wrong state, for example,VPDMA works abnormal,

we also have tested this on DVRRDK_04_01_00_02,this problem exits.

Buf on dm8168,it works all right when overflow occurs.

so is something wrong with 8148 overflow process ?

Could you please check if the reset sequence is called for the dm8148? if it is not, call it in case of overflow. i think this is alraedy taken care for dm8168.

YES，of course we have checked that,the reset operation is the major reason that resulted to this problem,if we don't do the reset sequence,it works right for a while,but still blocks when overflow occurs some times.

and there is another thing,this problem only exists with sc4,it' ok with sc3,but we cannot use sc3 anymore in current situation to avoid enlarging system burden.
