Hi Stephen,
Thank you for the response. There was a E2E forum titled "uboot splash screen for DM816X for SD/Dvo2" and I think we can switch to discuss this issue on that Forum. The title is realted to DM816x, not DM814x as this forum stated. Here is the link:

By the way, some how I can't access the app note from the link your posted. If possible, can you e-mail the file to my e-mail at frank_huang@bd.com? Thanks.
