the generation 2 model is pretty much the same the same as the Generation I model differences are that the that it has a different mtd layout and a faster CPU
# cat /proc/cpuinfo system type : TI AR7 (TNETD7200) processor : 0 cpu model : MIPS 4KEc V4.8 BogoMIPS : 211.35 wait instruction : yes microsecond timers : yes tlb_entries : 16 extra interrupt vector: yes hardware watchpoint : yes ASEs implemented : shadow register sets : 1 core : 0 VCED exceptions : not available VCEI exceptions : not available
note this router wasn't in working condition after the firmware upgrade
first off the Gen I upload script doesn't work someone could try modifying it to suite the new mtd layout I tried but gave up
grab a stable or trunk image, for example http://downloads.openwrt.org/backfire/10.03/ar7/openwrt-ar7-squashfs.bin this image has been tested (for only about 30m)
it's seems that the router will only respond to the IP address 192.168.1.1 turn off your router, set your ethernet card to 192.168.1.0/24 subnet
open a terminal
$ telnet 192.168.1.1 21 # turn on router and hit enter USER adam2 PASS adam2 GETENV mtd1 # check that mtd1 through 4 matches the one of the tables above ... GETENV mtd4 # if any of the settings don't match you probably # don't have the same router and I would recomend giving up now SETENV mtd1,0x90020000,0x903e0000 # this sets the new mtd layout for the # OpenWrt firmware ^]quit # quit out of the session
$ ftp 192.168.1.1 #login here ftp> quote MEDIA FLSH # sets the media to upload to ftp> binary # set binary mode ftp> hash # enable progresses meter ftp> put "path to firmware/openwrt-ar7-squashfs.bin" "fs mtd4" 200 Port command successful. # sorry my scrollback buffer only goes back this far 120 service ready in 32 seconds. # so everything before now is from memory #######...pauses here while erasing...###..lots more...######## 150 Opening BINARY mode data connection for file transfer. 2752516 bytes sent in 68.5 seconds (40191 bytes/s) ftp> quit 226 Transfer complete.
adam2 the boot loader doesn't seem to respond straight away. so try timing the ftp/telnet session for the end of the boot-load sequence, you can find this out by noting that the LED status will flash until about 20s in then the Ethernet LED will turn on. telnet/ftp in just before the Ethernet light turns on
- don't do the GETENV and SETENV from ftp because the client seems to get confused
- if you brick your router (you'll notice that the USB light will blink slowly after it's finished booting) adam2 won't work properly after the USB light starts blinking
- I flashed two GenII modems which had different adam2 IPs.
The difference appears to be indicated in P/N number:
ISL502TNTX used 192.168.1.1 ISL502TNNZ used 18.104.22.168
I (puck) have flashed two GENII modems with the following adam2 IPs:
ISL502TNNZ used 22.214.171.124 ISL502TNAU used 126.96.36.199
- To find out the IP address to use, you can telnet to the devices IP address (using a DHCP client on laptop/whatever when plugged into the DSL-502T while it is turned on)
And look for either ip_myaddress or IPA, you can set the address to something else for the next book by running:
echo "ip_myaddress 192.168.1.1" > /proc/ticfg/env
echo "IPA 192.168.1.1" > /proc/ticfg/env
- It seems that with 10.03.1-rc5 the ethernet LED doesn't work, I have been able to make the USB LED show the network activity though.
