IMX7 Dual MIPI DSI PHY Timings Calculation

fs27 — Tue, 10 Aug 2021 08:27:43 GMT

Hello,

we are currently using the IMX7Dual with the MIPI DSI Samsung driver. We have adapted the HX8363 driver for our custom display.

We modified the pixelclock and the display is not working correctly. Fbset reports the correct timings but measuring the MIPI DSI signals the frequency differs from the pixelclock.

After further investigation we saw that in the forums here a tool were mentioned to calculate the PHY timings. Where can I find this tool?

How are the PHY timings calculated, are they based on the resolution?

Hello @joanxie , could you send me an email? I would like to forward the NDA number as @fs27 is currently on vacation and we would need the datasheet asap.
