HDMI 'I2C Bus Low?' Errors

Hi Prabhakar,

Are you using EZSDK? If yes, make sure you are using the latest version of the EZSDK (5.05.02.00) with the latest version of the linux kernel:

http://arago-project.org/git/projects/?p=linux-omap3.git;a=shortlog;h=refs/heads/ti81xx-master

Are you using TI EVM or custom board?

See if the below e2e threads will be in help:

Hi Pavel,

Yes I am using the ti81xx-master branch itself. Yes its a custom board the i2c buffers connected to hdmi as same as on the evm.
I even tried pulling up the pin 78/79/111/112 but still the same issue.

Any pointers on how to proceed would be much appreciated ?

Thanks,
--Prabhakar Lad

Prabhakar,

Are you able to reproduce this issue on the TI EVM or this issue is valid only for custom board?

BR
Pavel

Hi Pavel,

The issue is valid on the custom board. HDMI works fine on EVM.

Thanks,
--Prabhakar

Prabhakar,

Then this should be HW related issue, and I can suggest you to double check the HW design of your custom board. Please refer to the routing, design and layout specifications in the HDMI section of the datasheet. Check also the below links and DM814x TI EVM schematics.

http://processors.wiki.ti.com/index.php/TI81XX_PSP_UBOOT_User_Guide#Board_Modification
http://processors.wiki.ti.com/index.php/DM814x_Hardware_Design_Guide

Double check also the sequence for inserting the HDMI module, described in the HDMI driver wiki:
http://processors.wiki.ti.com/index.php/TI81XX_PSP_HDMI_Driver_User_Guide
http://processors.wiki.ti.com/index.php/TI81XX_PSP_HDMI_Sii9022a_Transmitter_Driver_User_Guide

Check the below wiki page regarding the I2C side:

Pavel

Hi Pavel,

I see debug messages when I connect/disconnect the HDMI Cable, following is the log,
