Hi all,


I've got some question about SD card provided with DM36X EVM.

They are 3 partition: TRAGETFS, BOOT, START_HERE.

When I run the board in SD boot mode the system boot on the sytem boot on the partition BOOT???

This partition contained .
|-- boot.cmd
|-- boot.cmd~
|-- boot.scr
`-- uImage

Now I've got my personnal board and I want to change de timing DDR for this I've got to modify the file

/ti-dvsdk_dm368-evm_4_02_00_06/psp/flash-utils/DM36x/Common/src/device.c.

I've got modify the variable too

EXEC_DIR=/media/ROOTFS

in the file Rules.make


But when I make an "make linux_install" It's doesn't modifying the patition BOOT of my SD card.

Is it normal ?? What should I do if I want use modify Timing DDR and USE SD BOOT mode.


Regards

    Hi Maxime Suire,

         I think you are discussing three issues here.

         1.Refer to "How to create an SD card" section software developers guide in docs directory of your DVSDK installed location

         2. The "make linux_install" target meant to copy/install the newly created linux binaries to target file system, This does not do anything with SD card creation. Refer Software developer guide for more info.

         3. The steps you are following to change DDR timing is not correct, I am not very much expert here, But I think you need to start with the u-boot source code.

    Best Regards
