JFFS

Needed for ipkg so..

nvram set sys_enable_jffs2=1
nvram set sys_clean_jffs2=1
nvram set jffs_mounted=1
nvram commit
reboot

USB

usb mount at startup: small problems, will not "just" mount at startup as in How-to's

console mode
 > ~ # nvram set rc_startup="
 > for I in `/bin/ls /jffs/etc/config/*.startup`
 > do
 >    sh $I &
 > done
 > "
 > ~ # nvram commit
 >

not ok use

nvram set rc_startup='
for I in /jffs/etc/config/*.startup
do
  sh $I &
done
'

Actually, the dd-wrt sw starts *.startup in /jffs/etc/config/*.startup anyway Startup_Scripts#How_it_Works_3

Installation

1. Install the folowing modules for USB and filesystems:

 #
 ipkg install kmod-usb-uhci // this is for USB 1.1
 ipkg install kmod-usb-core
 ipkg install kmod-usb2
 #
 ipkg install kmod-usb-storage
 ipkg install kmod-vfat
 ipkg install kmod-ext2
 ipkg install kmod-ext3

A startup script must be made to start usb drivers on every reboot. Create a file, usb.startup in /jffs/etc/config/ directory that contains this which will also start fatfs :

#!/bin/sh
insmod /jffs/lib/modules/2.4.30/usbcore.o
insmod /jffs/lib/modules/2.4.30/ehci-hcd.o
insmod /jffs/lib/modules/2.4.30/scsi_mod.o
insmod /jffs/lib/modules/2.4.30/usb-storage.o
# remove the dash (#) from the line below if you use USB 1.1
#insmod /jffs/lib/modules/2.4.30/uhci.o
#
insmod /jffs/lib/modules/2.4.30/sd_mod.o
insmod /jffs/lib/modules/2.4.30/fat.o
insmod /jffs/lib/modules/2.4.30/vfat.o

Mounting

Unfortunatly, dd-wrt doesn't seem to look for a /jffs/etc/fstab ( fstab referenceh )

So we need to mount the USB in the script, so add:

mount /dev/scsi/host0/bus0/target0/lun0/part1 /mnt

Check the disk with ls

ls -l /mnt

One could alternativly make a script that parsed a /jffs/etc/fstab for the mount values instead of altering the script every time ...

 $(awk '/^\// {print "mount " $1 " " $2}' /jffs/etc/fstab)

More work

You can also add the above line to /jffs/etc/config/usb.startup to mount the partition on reboot

# multiple partitions
mkdir /tmp/usb/1
mount /dev/scsi/host0/bus0/target0/lun0/part1 /tmp/usb/1
# list its contents
ls -l /tmp/usb/1
# second partition
mkdir /tmp/usb/2
mount /dev/scsi/host0/bus0/target0/lun0/part2 /tmp/usb/2
# list its contents
ls -l /tmp/usb/2

In order to use a multislot card reader, you must add the following parameter to the scsi_mod in the file /jffs/etc/modules.d/60-usb-storage:

scsi_mod max_scsi_luns=8

ASUS 32MByte

mem ok with 32Mbyte

nvram set sdram_init=0x0009 
nvram set sdram_ncdl=0 
nvram commit 
reboot

Bluetooth

"Cool": someone has hooked bluetooth to Asus...

• Nice with PBX sw and a bluetooth headset (how to ring out ...hmm)
• Internet access for Mobil...
• GPS

Playtime

Serial/UART

• Max3232: Maxim's level converter 2 * ttl-rs232 @ 3.5v
• My friendly local electronics supplier in Sejs, Denmark

How does one upload gif/jpegs for display ....!!!???!!!

Brick

After first dd-wrt attempt: none since Had to short pins in the end

A funny thing happened after I dd-wrt'ed my boxes

You have probably NOT bricked your router if you continually loose wireless to it while going thru the panels.

Every time I left a dd-wrt www interface panel, with ping router and using wireless, I "lost" contact with the router. Repair wireless solved the problem until I moved between panels again.

This has happened on both the routers.

Be patient.

Add more memory.

The problem will go away.

(Needs more analysing)
