Home / Other I-Appliances / WebPal Possible new information regarding Webpal binary images? Interesting output from "strings" command

Possible new information regarding Webpal binary images? (modified 0 times) dflowerd Profile Hey there, it seems as though there's not much activity on this board anymore. I just picked up a webpal myself because it was cheap and looked interesting. Anyway, I've read what everyone else here wrote, and it seems as though noone ever was able to download their own binary image to this thing. I just ran one of the images from teknema through strings, and found some interesting output, especially the first few lines: In-place Decompressor --------------------- incomplete literal tree incomplete distance tree bad gzip magic numbers internal error, invalid method Input is encrypted Multi part input Input has invalid flags invalid compressed format (err=1) invalid compressed format (err=2) out of memory invalid compressed format (other) crc error length error ran out of input data -- System halted Uncompressing Application... done. Can I assume then that the OS is stored in a compressed format with GZIP? Does this help anything? 01-14-2001 20:38:12

RE:Possible new information regarding Webpal binary images? (modified 0 times) transiit Profile Yeah, I've run a number of their .erx images through strings and noticed similar results. gzip didn't want to decompress the entire image, so I wouldn't be surprised if there might be some sort of embedded gzipped archive somewhere in there. Someone who recognizes the format might be able to say for sure (else I'll have to go take a look at wotsit.org to see if they've got any information on that one) I've been keeping an archive of nearly every file I can find related to the webpal, and one of the more interesting ones was the teknema parallel debugging package. Essentially, it purports to be a few utils for dealing with these things, a README file with a wiring diagram for the cable, and a modified version of lp.c (linux kernel parallel port driver. looks like they got it from one of the 2.0.x kernels. I never had success building it on a 2.2.x system, and I'm pretty darn sure 2.4.x is right out.) I think I even have copies of their tools for dealing with images for the smartcard reader. -transiit 01-15-2001 00:15:03

RE:Possible new information regarding Webpal binary images? (modified 0 times) transiit Profile Everybody say "hoo-ray" for progress So I looked up some information on gzip file formats, and learned enough to determine that gzip archives start with the byte pattern "1f8b". So I grabbed one an upgrade image, opened it up in ghex, and did a search for such. Found it at 7E80. Decided it was likely the compressed image considering a large number of bytes preceding this were all 00. So I chopped off everything before that point, ran it through gzip (which complained of trailing garbage) and ran the result through strings. An exerpt from the result: tiber http://www.teknema.com/er/ `Easy Rider - Rel. 1.0a Copyright (C) 1996-1997, Teknema, Inc. -------------------------------------- Init Video........

Time to go poke around some more. -transiit 01-15-2001 17:28:40

RE:Possible new information regarding Webpal binary images? (modified 0 times) dflowerd Profile transiit, this is good news. I found an ARM disassembler this afternoon that I'm going to try to run one of the binaries through later tonight to see if I can decipher how it boots, and whether or not this is just a raw FLASH image or if it contains anything else. It seems as though being able to web-upgrade these things to some custom software is very possible and that we're very close to a solution for it... I wonder if those "Init <device>....." strings are what is sent out the serial port? I heard from someone that debugging info was sent over one of the serial ports that is visible on the motherboard... 01-15-2001 19:34:08
