Hi Robert. Thanks for your info. When you make partitions using sfdisk, where is the info written? Would the info overwrite the memory area of MLO or boot.img?
I have a problem when using this image. At boot I always get this message : [ 10.379089] libphy: PHY 4a101000.mdio:01 not found [ 10.384157] net eth0: phy 4a101000.mdio:01 not found on slave 1 whether or not I have a cable plugged in. But if I have the ethernet cable plugged in, the system booted up relatively quickly with the log in prompt, otherwise it will take about 100 seconds before the log in prompt appeared. And if I plug in a cable after booting up, it will take a long while before the cable is detected and even longer before an IP is assigned by the DHCP server. I tried changing the settings in "dhclient.conf" without any effect. What can I do to fix these problems? In the stock kernel that came with the board(Rev C), the same message appears but only after the log in prompt, and it doesn't block the other operations. I also read from the forum that the cape manager is gone in this kernel version(so soon!), so does that mean I have to put the capes I need in the am335x-boneblack.dts file and load everything at boot time? And how can I know what capes are loaded now without the "/sys/devices/bone_capemgr.*/ slots"? Thanks again for your help!
