TMS320DM8148: Is it possible to display boot logo ?

Guru 20755 points
Part Number: TMS320DM8148

Hello,

We need to display a logo in u-boot in dvo2 (vout0).

We once tried that, but it failed to work, so our first question is:

Is it possible to display boot logo in dvo2 ?

We found some relevant questions, but some of the answers say that it is impossible:

"23 Oct 2012 11:23 AM Vladimir-XID:  Hello, I am sorry, this information is not available. It is not possible to implement u-boot dvo2 splash screen. You could contact your local field engineer for more details. BR Vladimir "

If it is possible, is it documented anywhere how to achive it ?

Does it required and pathces in u-boot ?

Does it require a change in memory map ? (Isn't memory map - .bld relevant only for linux )?

Does it involve the vpss core ?

Thank you,

Ran

  • Hi Ran,

    The u-boot that comes with the EZSDK 5.05.02.00 support boot logo on DVO2/VOUT0/LCD. I would suggest you to download EZSDK and check the below resources:

    ti-ezsdk_dm814x-evm_5_05_02_00/docs/DM814x_EZ_Software_Developers_Guide.pdf, section 6.7 How to display a logo at boot
