Hi all, Regarding U-Boot 2012.07 & 2012.10 running on Overo IronSTORM DM3730, from the bootlog message "OMAP36XX/37XX-GP ES1.2, CPU-OPP2, L3-165MHz, Max CPU Clock 1 Ghz" How can I print out the actual running CPU clock and the associating L3 clock & IVA clock? I looked at the code and the string for L3 is static at 165MHz. Since the IronSTORM is paired with a Micron 200MHz LPDDR, I was expecting the message to show "L3-200MHz" instead. Can someone advice how I can patch U-Boot to show the real configured values dynamically? Thanks in adv. -- Regards, James |

Hi Ash, but from the Git log, http://git.sakoman.com/git/gitweb.cgi?p=u-boot.git;a=commit;h=5da8247817df2f79b1fd80d48eae58765b6553d5 It is already moved to 200MHz. >From the kernel bootlog with v2012.07 & v2012.10, "Clocking rate (Crystal/Core/MPU): 26.0/400/600 MHz Reprogramming SDRC clock to 400000000 Hz" Using the old X-loader v1.5.1 + U-Boot v2011.09, the kernel bootlog is "Clocking rate (Crystal/Core/MPU): 26.0/332/600 MHz Reprogramming SDRC clock to 332000000 Hz" Am I getting this wrongly interpreted? (^^,) Thus, what can I add to print a debug string to show the running L3 clock instead of the static number?
