AM62L: Clarification on MIPI DSI Resolution Support for AM62L (720x1280 vs. Specified Max 1920x1080)

liangwencong

Part Number: AM62L

Tool/software:

Question:
While debugging MIPI DSI display on AM62L (CMD mode), the hardware initialization succeeds and data transmission to the 720x1280 panel is confirmed via kernel state logs (dri/0/state). However, the display fails to illuminate.

The datasheet specifies:

"Single display support up to 1920x1080 @ 60fps"

Given that our panel’s vertical resolution (1280) exceeds 1080, is this likely the root cause?

If so, does the 1080p limit apply strictly to vertical resolution?
If not, what other factors (e.g., timing constraints, burst mode requirements) should be verified for 720x1280 support?

Hi Liangwencong,

This thread is being re-assigned to the correct team. Please, expect some delay in the response.

We do not yet support CMD mode on AM62L.

No and no.

A typical rule of thumb is, your h_act*v_act*fps <= 1920*1080*60, then it can be supported.
