AM69: Concurrent DP/DSI display usage

fd

Part Number: AM69
Other Parts Discussed in Thread: AM67

Tool/software:

Hello,

is it possible to use at the same time the following 3 display outputs, DP, DSI1 and DSI2, on TI AM69 ?

Given this from the TIDSS Linux driver we have some concern:

/* Currently hard coded VP routing (see dispc_initial_config()) */
    .output_type = { DISPC_OUTPUT_INTERNAL, DISPC_OUTPUT_DPI,
             DISPC_OUTPUT_INTERNAL, DISPC_OUTPUT_DPI, },

In general DP, DSI1 and DSI2 would need to use DISPC_OUTPUT_INTERNAL, but only 2 ports seem to be available.

    Hi fd,

    I am checking with our SDK team on this.

    I have knowledge that we will have support for 3 display on AM67 platform starting next 10.0 SDK release. However, I will need to check whether the same is true for AM69.

    As a warning, our display driver owner is out until next week so responses will be delayed.

    Regards,

    Takuma

    Hi fd,

    It looks like only 2 displays are supported for AM69. Triple display support is for AM67 only.

    Edit May 21, 2025: We have only 2 output display ports one HDMI and another DP (AM69).
    There are 4 VideoPorts that TIDSS supports. And these ports can drive out different kind of signals.
    The routing on our boards have it to HDMI and DP.
    Custom boards can still drive 4 displays but we cannot test that on our EVMs.

    *Software support for more than 2 displays will be limited as such, due to no testing during SDK release, since testing is done using EVM

    Regards,
