Hi, I accidentally erased my nand flash on the DM355 EVM board. As a result, the UBL and the u-boot were all gone. Fortunately, there is the serial port tool to burn the UBL and u-boot ( http://wiki.davincidsp.com/index.php?title=Serial_Boot_and_Flash_Loading_Utility ) . I did that, and my board came back to live. But there is a problem, now when I run the encodedecode demo, a lot of annoying noise/flicker pop up everywhere on the screen, and the frame rate drops to < 20fps. I tried the "writeb" program from (http://linux.omap.com/pipermail/davinci-linux-open-source/2008-June/007264.html), it doesn't help. The demo ran well with my old UBL and u-boot. Since I use the same u-boot, I guess the problem must be the UBL coming with the Serial Flash Loading Utility. This tool can't load other UBL except for its own.
Does anyone know how to load the UBL without a JTAG emulator (I don't have one)? Or someone has similar experience? Thanks a lot! Richard
