Hi, For using zero bootdelay it is recommended to use CONFIG_ZERO_BOOTDELAY_CHECK config check so as to stop autoboot even if bootdelay is 0. It seems this config option is not working in davinci. Any ideas ?

I have a new question: I want to improve the performance of the CE Server on the DSP side; I know there are L1 and L2 caches and the actual amount can be configured in the *.tcf file of the CE server. 1) Do I have to activate these caches in my DSP code or are they already set up to run automatically by the CE Server initialization routine? 2) Also, I may want to use some of the L2 cache as IRAM or some of the L1 cache as L1SDRAM (I know how to configure these in the *.tcf file) but I don't know how to declare my data to map to these fast memory regions. For example, let's say my encoder codec has an array and I want fast access to it, it is declared as follows: XDAS_Int32 myArray[100]; // 400 bytes How do create a link file to force "myArray" to link to the beginning L1SRAM? The DVEVM codecs / servers examples automatically generate all the link files (*.cmd) in package/cfg, so I'm assuming it has to be done somewhere in one of the *.bld, *.cfg, or *.tcf files, am I correct? Can anyone please give me some pointers on how to link data to IRAM or L1SDRAM? Thanks! Regards, Andy -------------- next part -------------- An HTML attachment was scrubbed...

Even we can boot from NAND, our DSP algorithm can not work. Our embedded department people told me this is because we have to set SWITCH3-4 to OFF in order to boot from NAND. TI FAE seems mail us an diver to solve this, but we do not know how to use it.

It looks as if the boot loader is the only update. If you do a diff against the u-boot sources of your working version you should see the differences - when I checked it seemed they mainly changed the initialization for the internal DSP power control. It was not properly activated in the V1.10 boot loader so they gave the temporary SW3-4 workaround to set the DSP for self-boot, which as a side-effect activates the DSP power domain. By the way: 1. Does anyone have sources for the first bootloader in NAND (the max 14 kB loader)? We only have a .bin file. 2. Does anyone know the proper U-boot configuration for NAND flash booting?
