| So far, it is checking out the latest gPXE source from Git and building it (see the build logs on the BuildBot web interface; currently this is an incremental build with no make clean step, but that can easily be changed). | So far, it is checking out the latest gPXE source from Git and building it (see the build logs on the BuildBot web interface; currently this is an incremental build with no make clean step, but that can easily be changed). | ||

| + | ==== Wednesday, June 3 ==== | ||
| + | |||
| + | === Linux serial console === | ||
| + | |||
| + | Experimenting with Linux serial console for testing purposes; in conjunction with qemu's -serial stdio and -nographic, this should allow easy automated testing of Linux kernel booting. | ||
| + | |||
| + | Example: (append to kernel command line; this line works fine for qemu) | ||
| + | |||
| + | console=ttyS0,115200 | ||
| + | |||
| + | === mkbootfs === | ||
| + | |||
| + | Building a basic Linux environment with [[http://git.etherboot.org/?p=people/mcb30/mkbootfs.git|mkbootfs]]; need to install uClibc first, so I am setting up a toolchain with [[http://buildroot.uclibc.org/|Buildroot]]. | ||
| + | |||
| + | ==== Thursday, June 4 ==== | ||
| + | |||
| + | More uClibc build wrangling; the toolchain was missing pieces (cc1, at least), so I rebuilt it, but now it seems to be dynamically linked against uClibc, which is not available on the host. Following directions at http://buildroot.uclibc.org/buildroot.html but the instructions are not completely clear when it comes to building only a toolchain usable on the host. | ||
| + | |||
| + | ==== Friday, June 5 ==== | ||
| + | |||
| + | Made some progress with mkrootfs build; found the proper uClibc tools in buildroot's build_i686/staging_dir/usr/bin directory, but named as i686-linux-*, so now my uclibc wrapper script looks like this: | ||
| + | |||
| + | #!/bin/sh | ||
| + | export PATH=~/src/buildroot/buildroot-2009.05/build_i686/staging_dir/usr/bin:$PATH | ||
| + | export CROSS_COMPILE=i686-linux- | ||
| + | $@ | ||
| + | |||
| + | Now I am hitting a problem with uClibc configuration (need large file support, which wasn't enabled in my build), so I must rebuild uClibc, but things are looking better. | ||
| + | |||
| + | Had IRC meeting with mcb30, mdc, and AndyTim - set goals for week 3 (write up and execute 4 test cases). | ||
| + | |||
| + | More progress on mkbootfs: after rebuilding with large file support, compilation gets farther, but now breaks with "You need to build uClibc with UCLIBC_HAS_RPC for NFS support." - rebuilding uClibc again. | ||
