DM355 serial / SD card flash utility supporting mDDR

Aditya Pogade55079

Hello All,

We are using DM355 in one of my video application. The board supports mDDR memory. I think the utility present at http://processors.wiki.ti.com/index.php/Serial_Boot_and_Flash_Loading_Utility supports DDR2 memory. Can anybody please provide me modified utility for mDDR changes.

THanks in advance!!

Best regards,

Aditya

Aditya,

I can not provide you a modified utility with mobile DDR settings, but I can provide you some reference code to configure the mobile DDR in dm355. Please see the following forum post which has some sample code for initializing mobile DDR. (This can also be found by using the forum search feature for future reference in searching for similar topics)

Thanks a lot Miguel!!

The board is working now after modifying timer and PLL settings for mDDR. I am attaching the files which we modified to make it work. Designers who face similar problem can simply use these.

replace the flash_utils/DM35x/Common/src/device.c with the device.c in attachement
&
replace the flash_utils/DM35x/Common/include/device.h with the device.h in attachement

Thanks & regards,
