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 ?

Hi all,

Thanks to all who responded about the small footprint filesystem; they were all 
very helpful.  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

hi all:
    when I executed "./loadmodules.sh", I got following error message:
cmem initialized 3 pools between  0x87800000 and 0x88000000 dsplinkk: no 
version for "struct_module" found: kernel tainted.DDR_START  0x8fa00000  
DDR_SIZE 0x400000
    then I executed "./encodedecode". I found the image just display top 
half of LCD monitor and the frame  rate is very low. I want to konw wether 
the top error result in these issues occur?
     Thanks and Regards,
     -sorryboyx

Thanks for the information.

I will inform the corresponding person, and report you the following status.

Hi,

Here is our current status:

We can use elder u-boot to flash 1.10 uImge into NAND FLASH.
but can not use the latest u-boot, even we rebuild it with different
compiler option.

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.

Any suggestion?

Hi Steve, 

The newest DVEVM software release 1.10.01 on the TI site has a new
u-boot loader (only compiled for NOR flash, but with sources) that does
fix the SW3-4 problem. 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?

Regards,
Arie de Muijnck
