i.Mx53 how to decide Drive strength in IOMUX?

Discussion created by positron positron on Apr 28, 2012

In the u-boot there is a imximage.cfg file where the DCD headers are filled with default values for DRAM and other stuff.

In that, the field which differs is that the 'DSE' Drive field strength, bits (19-21) in IMOUX registers.

Any idea on how to find out the output impedance for a particular pin?

In the manual it says 'based on ddr_sel value'. How to interpret this? Anyone who customized u-boot for custom mx53 based boards, Ideas/suggestions please.
