So, I've tested this a few times over the last . . .<whatever it's been since announcement >, and I have found that loading a single overlay seems to work really good. Attempting multiple overlays however, seems to be an exercise in frustration. e.g. It's not ready. It's possible that I got something wrong, but I do not usually do that more than once. I've tried multiple times.
So my recommendation is, if you're an embedded Linux noob, or a beginner to this platforms boot process. Steer clear. If you're reasonably experienced in both of these areas, and don't mind testing - Have fun. But I would definitely strongly advise to not attempt this on a production system. Basically what happens is uboot complains that the cmdline kernel parameter does not contain a valid flattened device tree overlay path. Why exactly, I'm not sure. I did see uboot "mention" that it can not find a valid partition for partitions 1-6 . . . which I think may be standard uboot debug output. First, it checked the path for the UUID, then attempted the blk device. Failing ( or flailing ). However, this works perfectly fine when using: ##Example v4.1.x > #cape_disable=bone_capemgr.disable_partno= > cape_enable=bone_capemgr.enable_partno=controller,BB-ADC,BB-W1-P8.26 > After making sure the overlays exist in /lib/firmware/, and then running: root@beaglebone:~# cd /opt/scripts/tools/developers/ > root@beaglebone:/opt/scripts/tools/developers# ./update_initrd.sh > root@beaglebone:/opt/scripts/tools/developers# reboot > One should also keep in mind that if you update to a newer kernel before this process. Make sure you reboot into your new kernel first. Otherwise your board *WILL* boot, but the boot process will stop inside the initramfs. I fell into this trap myself, and basically what happens. You will end up updating the initramfs you just replaced, while leaving the replacement initramfs without a clue as to where to go next. Once the initramfs loads that is. Anyway, this is a potentially really cool, and good feature. I look forward to this working flawlessly in the future. However, at this point in time, I have to give testing a pass. As I have other priorities that must come first - currently. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
