AM62A7: Probability of timing errors in data obtained by lt9211

Part Number: AM62A7

Tool/software:

Dear TI,

I used the sdk 10.01 and want to enable the LT9211 to transfer dpi from soc to lvds.

However, I found that somtimes the screen parameter data obtained by the lt9211 driver is inconsistent with the settings set by the panel-simple driver.

Firstly, I set the screen parameters in panel-simple.c

then  i use command modetest -M tidss to get panel params.

however, when lt9211 driver analysis the dpi data, hfp, hs, hbp, hact, htotal data are different.

This ultimately led to jagged edges on the screen.

Thanks

  • Hi,
    We do not have the capability to test lt9211 on our EVMs. You may probe DPI output and crosscheck if you are seeing correct porches or not. 
    The incorrect detection of porches by the bridge seems to be more of a lt9211 driver issue and would recommend checking with the bridge vendor.
