Hi,
A few days ago I was going to do an evaluation using L138 experimenter kit. DVSDK 4.02.00.06 was installed in a Ubuntu virtual machine successfully, the configuration was done with only one problem that I could not get experimenter kit uboot configured through Minicom, but it's solved by manually changing the boot arguments(I was going to use TFTP and NFS to boot up the system). Hooking up everything and turning on the experimenter kit, it booted up, but it hung just before the boot process was almost done. Below are the boot messages, the last message was different each time, but after 1st CMEM module related message. Also I found that when the system hung, the L138 CPU's temperature rose up near 60C in a few minutes.
