Hello Team,
My customer wants to implement SWA for attached errata.
TI_DS90Ux940N_Communication_Oct312018.pdf
So I will need let them have any kind of simple guide about this.
I understand as below.
Issue #2, need to change indirect address not to have CSI page corruption.
Issue #3, SOC which received CSI output from 940 needs to monitor CSI SOT/data error.
if any detect error by SOC, will do write 0x40 to 0x4b and rewrite 0x40 to 0x43 for restarting CSI PLL logic.
but because 940 doesn't have capability of CSI output monitoring, SOC keep monitoring if any SOT/data error of 940 CSI output
Issue #5, I understand that UB940 device works as HDCP device so it can enter AV mute mode.
so SER can block to send data during blank than DES will not enter HDCP AV mute mode.
so I want to check with you for several question.
1) all above my understanding is correct?
2) For issue #1, trimmed register will be re-loaded by write 0x01 bit[0],bit[1]. in this case. after re-loaded, is there any side effect of this errata??
3) For issue #3, why user need to check CSI Pass register??
Thanks
