2011-10-17 16:11:46     Modify SDRAM control registers

Hi Guys,

 

What is the best/easiest way to modify the SDRAM control registers (of BF537) from the u-boot running in RAM?

For the PLL register there is an "PLL Programming Sequence" described in the datasheet.

Can we apply something like this in our case?

 

Thank you!

Dimitar

You should post this question in uboot help forum other than the Linux help forum.

If you are trying to adjust your DRAM setting, just modify them in the code as described in   docs.blackfin.uclinux.org/doku.php?id=bootloaders:u-boot:porting.
