DDR2 in DM6446 custom design

Other Parts Discussed in Thread: TMS320DM6446

Hi to all,

In our custom design with TMS320DM6446 I would like to learn the functions that are DM6446EVM specific and where they are included in . For example do I have to patch all the three UBL, UBOOT and UIMAGE files if the clock rate of the DDR2 in the custom design is not 267 MHz but 333MHz with data rate 667 MT/s and same depth and width 64 x16 ?

Thanks

In general if you want to update DDR timing, you can do so in the UBL ->device.c file. For more info, you should contact the linux forum.

Thank you Yin,

I found the UBL->device.c in DM644x_FlashAndBootUtils_2_00 project , will try to compile the ubl and will try to change DDR timings.

Do you know whether the ubl source code has EVM specific definitions or not? For example how can I remove the MSP430 related codes?
