Hi there,
short introduction of mine because I'm new here: mid 40, father and husband, carpenter, using Linux since 15 years, weak skills on Uboot because of two Marvell Sheevas running Debian.
I own an internet radio (running ucLinux, architecture blackfin) which is not able to get the time from a NTP server, because it only uses one IP. And this one does not respond on queries. I'm not amazed about that, the server is in HongKong. So I thought if it is possible to 'hack' the firmware of this device to edit the ntp.conf This firmware consist of 4 parts: header, 2 gzip archives and one uImage.
For this uImage 'mkimage -l' tells me the following: Image Name: uClinux Kernel and ext2 Created: Thu Jun 18 04:42:13 2009 Image Type: Unknown Architecture Linux Kernel Image (gzip compressed) Data Size: 2230245 Bytes = 2177.97 kB = 2.13 MB Load Address: 0x00001000 Entry Point: 0x00001000
I can extract it by using extract_uimage.sh from here: http://buffalo.nas-central.org/wiki/How_to_Extract_an_uImage
Now it seems I have an gzip image. Ok gunzipping it shows me something with clear text in it.
Is there any chance to see the ext2 in this image by using a special sequence of bytes?
Hoping for help or hints
best regards Frank
