Also, the bootargs are not getting passed to the kernel, so might be same for memory tag? > Best regards, > > Wolfgang Denk > > -- > DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel > HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany > Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: w...@denx.de > Weekends were made for programming. - Karl Lehenbauer ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

You RAM initialization in U-Boot seems to be broken. Check the number of rows/columns you program into your memory controller.

[U-Boot] Linux kernel only reporting 16M / 128M
Greetings, My flashing issues are now gone and will adress this later on. Anyhow, I noticed that linux kernel only reports 16M total memory while the board got 128M. Was just wondering where to start looking? Everything works fine inside u-boot so its not passed correctly or something, not sure how the linux kernel detects that. Any thoughts are helpful.
