# The default DSL-502T mtd map looks like this:
|
|
#
|
|
# mtd0 0x90091000,0x903f0000 # filesystem
|
|
# mtd1 0x90010090,0x90091000 # kernel
|
|
# mtd2 0x90000000,0x90010000 # bootloader - DO NOT MODIFY
|
|
# mtd3 0x903f0000,0x90400000 # config space - DO NOT MODIFY
|
|
# mtd4 0x90010000,0x903f0000 # firmware signature + kernel + filesystem, used to flash new firmware
|
|
#
|
|
# i.e. the flash layout is:
|
|
#
|
|
# 90000000-9000FFFF mtd2 bootloader
|
|
# 90010000-9001008F ---- firmware signature )
|
|
# 90010090-90090FFF mtd1 kernel ) mtd4 spans these three regions
|
|
# 90091000-903EFFFF mtd0 filesystem )
|
|
# 903F0000-903FFFFF mtd3 config space
|
|
#
|
|
# The ADAM2 bootloader uses the mtd1 settings to find the start of the image to boot.
|
|
# The image to load contains information about the loadable size of the image. If ADAM2 sees
|
|
# that the image appears to extend beyond the end of mtd1, it will refuse to load it. On
|
|
# the DSL-502T, this manifests as the USB light blinking rapidly on boot.
|
|
#
|
|
# The OpenWRT kernel does not follow quite the same layout:
|
|
# (a) it does not have a 0x90-byte firmware signature prefix
|
|
# (b) it is larger than the default mtd1 size
|
|
#
|
|
# (a) would be avoidable (build a custom image with a 0x90-byte prefix) but (b) is unavoidable.
|
|
# So we *have* to change mtd1. The simplest thing to do seems to make it span all of
|
|
# the flashable area, producing this layout:
|
|
#
|
|
# mtd0 0x90091000,0x903f0000 # filesystem
|
|
# mtd1 0x90010000,0x903f0000 # kernel (CHANGED)
|
|
# mtd2 0x90000000,0x90010000 # bootloader - DO NOT MODIFY
|
|
# mtd3 0x903f0000,0x90400000 # config space - DO NOT MODIFY
|
|
# mtd4 0x90010000,0x903f0000 # kernel + filesystem, used to flash new firmware
|
|
#
|
|
# *** NOTE NOTE NOTE NOTE ***
|
|
#
|
|
# /dev/mtd0 .. /dev/mtd4 when using OpenWRT do **NOT** correspond to the ADAM2 mtd0-4 settings!
|
|
# Instead, OpenWRT scans the MTD itself and determines its own boundaries which are arranged
|
|
# quite differently to ADAM2. It will look something like this, see dmsg on boot:
|
|
#
|
|
# (/dev/mtd0) 0x00000000-0x00010000 : "loader" # Bootloader, read-only
|
|
# (/dev/mtd1) 0x003f0000-0x00400000 : "config" # Config space
|
|
# (/dev/mtd2) 0x00010000-0x003f0000 : "linux" # Firmware area (kernel + root fs + JFFS area)
|
|
# (/dev/mtd3) 0x000d0d58-0x003f0000 : "rootfs" # Root FS, starts immediately after kernel
|
|
# (/dev/mtd4) 0x00280000-0x003f0000 : "rootfs_data" # If rootfs is squashfs, start of JFFS area.
|
|
#
|
|
# All of those boundaries are autodetected by examining the data in flash.
