Part Number: PROCESSOR-SDK-AM67
Other Parts Discussed in Thread: AM67

Tool/software:

Customer are using AM67 and ADV7535 as bridge to support DSI to HDMI.

And here is their dts file, could you please help to check the configuration, Thanks.

Hi Zekun,

Which output resolution are you try to get out of DSI? Also are you trying out on AM67 EVM?

Also which sysclk is used on this board? Essentially we need to understand what's difference from the EVM?

Hi Brijesh,

sysclk is 25M, resolution is 1920x1080.
my new dsi config and kernel log is below

I can access ADV7535 registers, the address is 0x3d.

When I config dsi0 out to panel (raspberrypi,7inch-dsi), dsi0 has clock output, but dsi0 no data output, how to config DSI0_TXNx/TXPx?

When I config dsi0 -> adb7535 ->hdmi, dsi0 no clock and data output, it is seem than the dts config issue, can you provide a config of dsi0->adb7535->hdmi to test?

Thanks

Brijesh,

This is TI FAE, customer design refer Beagle AI and use DSI to HDMI bridge to support display.

EVM uses DPI to HDMI bridge and customer use ADV7535 because they ever used ADV7535 with other ARM SOC in other projects.

We assume the ADV7535 initialization should be same as other project but we cannot confirm this.

Customer had enabled DT overlay to DSI follow below instruction and see DSI clock output.

Also confirm I2C0 can read/write ADV7535 successfully.

Could you review the config file and advise what other input you need?

To enable these displays on AM62P5-SK, refer the How to enable DT overlays in linux guide, and enable the k3-am62p5-sk-microtips-mf101hie-panel.dtbo DT overlay for OLDI output, and k3-am62p5-sk-dsi-rpi-7inch-panel.dtbo DT overlay for the DSI output.

Hi Rich,

I responded to the previous thread: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1454230/processor-sdk-am67-sdk-9-2-am6734-dsi-converter-to-hdmi-config.

In addition to the response in previous thread, reviewing the config file, I see a lot of fields that are required in devicetree bindings documentation are omitted for the adi,adv7535 bridge: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/Documentation/devicetree/bindings/display/bridge/adi,adv7533.yaml?h=ti-linux-6.1.y.

If this bridge has been used in a previous project, and if Linux driver is being used in the previous project, I would recommend checking the device tree node for the bridge device. If Linux is not used, I would recommend checking if all of the registers that are touched in the previous project are configured by the Linux driver. For example, I do not see clock or interrupt, or the "edid" register defined in your shared dts file, but the devicetree bindings yaml file example are defining all of these.

Regards,

Takuma
