Hello,

 

For a custom board using the H5 or H3 SoC, i would like to make the Calibration of the DDR3 chip. I think that the available information is very little.

 

I will report here the steps I am taking. Anyway, I would greatly appreciate any information that could be provided to me.

 

Thanks in advance

I don't think any AW board has custom DDR settings. H3 & H5 DDR3 driver currently supports only 1333MHz timings. It would be great to enable per-board settings, but you will have to come up with that yourself. Remember, there is no documentation for DRAM controller, so all that was reverse engineered.
