Dear All,
We have our own customized board where we are using omap-l138 with mDDR MT46H128M16LFCK-6:A.
But we are facing a problem in proper reading of DRAM in u-boot.
We are using 256MB of mDDR but we get value in u-boot of 128MB.Following is the debug at u-boot prompt:
We have also gone through the arm ubl of 1.65 version. Where we have made change in th SDCR register i.e. page size set 2048 and IBANK set 4 banks, as per our mDDR settings.
Please do correct where we are going wrong and for more info just reply the post.
OMAP-L138 initialization passed!
