Hi, I've downloaded the kernel and toolchain for ttgo 7.9 + the example program for the 2.4 kernel (tomtom go 4.0). I've set it all up in a directory according to an example somewhere in the wiki. I use the build script to build the ttsystem image and transfer it to the tomtom.
However when connecting t the tty on the serial port I get the following output. unpacking initramfs...<0>Kernel panic - not syncing: bad initramfs (no cpio magic) Has anybody else seen this, I haven't really changed anything and I haven't seen any errors when building. I assume the kernel has built fine but something is not right with the settings for the embedded file system or the script making the image. Any suggestions would be appreciated.
