Now that my custom DM6467T seems to be working, I find that when it boots totally from NAND (ubl/uboot/kernel/fs), it's VERY slow. It takes 2 to 2.6 MINUTES between power on to video output. Why?
I need to do more detailed timing to find where it's slowing down the most, but one distinct place is in the load of a codec server of a single codec. With NFS as root FS, the codec load took perhaps 15 to 30 seconds. Now, with NAND fs as root, it takes up to a minute, perhaps more. Why?
More importantly, is there something I can do about this? For one, I'll try trimming the kernel down to the essentials. But otherwise, what can I do to speed up this process?
Thanks in advance for your help,
Helmut
