Thanks for the advice Robert! I am currently working thru the same page, more or less as a student :-) And you suggestions sound excellent. I would be interested to hear you advice on selecting Kernel build options, from the menu. Do you think there is such a thing as a "default" configuration ??
Bill currently working my way through RCN's eewiki beaglebone page here: https://eewiki.net/display/linuxonarm/BeagleBone+Black and for others who also teach EL classes, here's something i do that seems to be a bit different from most presentations (and online pages) i've seen. most presentations seem to like downloading and building *everything* (MLO, u-boot, kernel, dtb and rootfs) before getting around to formatting an SD card, copying it all on, then testing. when i'm presenting this, i prefer to do the creation and testing in bite-size pieces to isolate build errors much faster. for instance, i will get students to do nothing more than download u-boot source, possibly patch it, cross-compile, then copy MLO and u-boot.img to the SD card and try to boot that. as long as the class has access to the serial port (i'm assuming that), the only test they'll be making is if u-boot comes up, and they can stop there and look around. they'll know they can't go any further, but that's all right -- that at least verifies that their build and install of u-boot seems to be fine, and if it isn't, debugging should be easy. once that's verified, move on to format the rest of the SD card and copy, say, just the kernel and dtb file, then try to boot *that*. again, students will understand there's no rootfs but all they're testing is if the kernel seems to load and boot. and if it fails, once again, debugging should be easy. finally, add the rootfs. anyway, that's the approach i prefer, and it seems to work as students like to be able to build *and test* something fairly quickly, rather than just doing a massive amount of work, and wondering if it will work in the end. rday -- ======================================================================== Robert P.
