hi dumdan,

you are very close to sucess.

1. start with minimal kernel config, (copy kernel2.config to .config).

2. check if you have network support and your opencore emac / tdk phy in kernel menuconfig, better compile-in kernel, instead of modules.

ie, minimal config + network + emac + phy

3. cfi, mtd,ramdisk,and kernel command line are not required in kernel config, because we use initramfs.

4. boot uclinux, and check if the eth0 init sucessfully.

Hi hippo,

Thanks for the prompt answer.

You see, my network driver is not really ready, yet. So, for my tests I configured the kernel without network support (NO NET).

For the network part I was, mostly, concerned with why I still see some netwiork messages. The network is not a major concern of mine, just yet.

Now, I know the goal here is to be able to use initramfs and, because of that, the cfi & mtd-related messages are what i&#39;m concerned about.

failed to ioremap

.....

mtd: partition "romfs" is out of reach -- disabled

....

Where do these come from and what (if anything) should I do about them ?

(of course, I could read the sources and figure out for myself, but the time I have is very, very limitted)

Also, I am going to need access to the flash in the very near future, so I&#39;d like to be able to mount readonly a flash partition, if at all possible. That&#39;s why I did not totaly removed the MTD and CFI options.

What would be the minmal options to be able to access the AMD flash on the eval board and nothing else ?

Thanks again,

Daniel
