S3C2410 MMC / Linux 2.6.19

1.Get s3c2420 mmc from http://www.handhelds.org/moin/moin.cgi/HpIpaqH1940Downloads

2.The linux DMA stack has been modified since 2.6.18
Fix s3c2410mci.h

#define S3C2410SDI_DMA DMACH_SDI

3.make zImage
4.Create device node
mknod mmcblk0 b 254 0
mknod mmcblk0p1 b 254 1

5.mount sd card
mount -t vfat -o sync /dev/mmcblk0p1 /mnt

Linux USB Ethernet/RNDIS gadget

From http://embedded.seattle.intel-research.net/wiki/index.php?title=Setting_up_USBnet

Currently the Linux kernel supports a CDC Ethernet USB Gadget driver (see USBnet (http://www.linux-usb.org/usbnet/) for more information); however, Windows in unable to use this device because it only support RNDIS Ethernet drivers (the CDC Ethernet driver does work under Linux though).

I'm fail to running Linux USB Ethernet/RNDIS gadget with Windows XP by MS default RNDIS driver. (Error code 10).

Finally I found MCCI RNDIS (Evalution version). It works.

I get it from http://members.driverguide.com/driver/detail.php?driverid=557038

1.Linux Ethernet/RNDIS device

ifconfig usb0 10.0.0.1

2.Windows Ethernet/RNDIS host

Set IP address for Eval MCCI?USB networking device (NDIS 5)

For example 10.0.0.2

Then it works as a real ethernet connection ...

Howto initramfs on linux-2.6.x

@Create external cpio archie

1.Create root file system on $BUSYBOX/ramdisk
2.cd $BUSYBOX/ramdisk
3.find . | cpio -o -H newc > ../initramfs.cpio
4.cp $BUSYBOX/initramfs.cpio $KERNEL/usr
5.cd $KERNEL
6.Set kernel config -> CONFIG_INITRAMFS_SOURCE="usr/initramfs.cpio"
7.make zImage

Note:Busybox can be dynamic linked, but be sure shared libraries in /lib

        /*
         * check if there is an early userspace init. If yes, let it do all
         * the work
         */

        if (!ramdisk_execute_command)
                ramdisk_execute_command = "/init"; <- Symblic link /init to /bin/sh. We can run into shell and never return

        if (sys_access((const char __user *) ramdisk_execute_command, 0) != 0) {
                ramdisk_execute_command = NULL;
                prepare_namespace();
        }

@Create cpio archie by script

1.Create script file $KERNEL/usr/cpio_list
