Title: TSP interface
Hello,

I work on Firefly rk3288 and i saw that all TSP (transport stream) pins are not outputed of the main chip...
So it's not possible to feed an external TS to this card.... very very sad because the main goal of this card is video ....

I hope that's a mistake from my side.

Hello,

Nobody can say if i'm wrong or right ?

Nobody from firefly team can confirm if TS input is available or not ?

Support is too poor for this card !!!!

Hi fd101283,

I'm really interested in using TS input on firefly too. I guess that dedicated pins don't make one way through the firefly layout.
Rockchip leaves a lack of documentation about that chip, and no one example exists about TS implementation.

Someone got some info/tuto/examples about that?

You're right. TS input pins are not exported. Therefore you cannot use them.

Thanks for the answer. It's what I expected. Bad news !

TSP signals are present in J11 and J14 on firefly reload base board as
J14    GPIO5_C2_D pin 25 mapped to TS0 Clk pin AE6 of processor
         GPIO5_C1_D pin 26 mapped to TS0 VAL pin AA9 of processor
         GPIO5_C3_D pin 24 mapped to TS0 ERR pin AE6 of processor
J11    SPI0_CSN1 pin  19 mapped to TS0 SYNC pin AG5 of processor
J11    SPIO_RXD pin 21 mapped to TS0 DAT7 pin AF6  OF PROCESSOR
However unable to locate the TS0 sources...
