Hello, I've made some changes to the Compaq bootldr program which I thought might be of interest to people who want to start playing with JFFS. The program also now works correctly on Assabet/Neponset. Briefly, the changes allow the bootldr to boot a kernel image directly from a JFFS partition in flash. Support for kernel configuration via a lilo.conf-like file is also included. If you'd like to begin working with these bootldr extensions, the patch is available at: ftp://ftp.wearablegroup.org/pub/software/patches/bootldr-jd2.patch.gz [1] The patch was developed on an Assabet with 4MB flash; you will need to add the appropriate JFFS partition descriptor to the bootldr code if you have different parts. In addition, you may need to tweak some values in the kernel itself in order to help it find the JFFS partition and use it for the root filesystem device. Depending on your machine, you may also need to edit the description for your hardware to specify the location of the boot arguments. I'd be very grateful for bug reports. Finally, an obligatory warning: this patch introduces new selection logic around almost every piece of code that uses the UARTs. Don't even think about trying it out on a machine for which you don't have a JTAG cable. Have fun, -jd [1] Patch is against bootldr CVS contents as of Sunday, 26 November, 2000. Included is a copy of the GPL, which is intended to cover the contents of the patch only (not the entire program). _______________________________________________ http://lists.arm.linux.org.uk/mailman/listinfo/linux-arm
