Message-ID: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Hi, I have an image which is 1.5MB in size after compression, thats is done for MCF5271. When i try to load this on a MCF5271 eval board using u-boot 1.2.0 it takes about 25 secs to just uncompress. I loaded a MCF5272 eval board with U- Boot 1.2.0 and then tried to start the same image(which was done for MCF5271). It was very fast. The checksum verification finish off in a second and uncompression in 10 seconds ! The clock configurations for both are provided below: M5272C3.h define CFG_HZ 1000 #define CFG_CLK 66000000 M5271EVB.h: define CFG_HZ 1000000 #define CFG_CLK 100000000 What should I do to get the image to uncompress faster in the MCF5271 EVB? Regards, Adarsh.
