  • [14:00:35] <sakoman> Crofton: nice! is the script available in .dev?
  • [14:02:33] <Crofton> there are like three lines to add to local.conf
  • [14:02:46] <Crofton> I think we are in testing mode atm
  • [14:02:54] <Crofton> I asked for build host info :)
  • [14:04:37] <sakoman> very handy feature!
  • [14:05:44] <sakoman> my beagleboard doesn't work very reliably when powered from USB. Much better when provided with 5V from a bench supply
  • [14:07:28] <koen> haven't noticed much difference
  • [14:08:42] <sakoman> mine will only boot about 10% of the time powered from USB, 100% from bench supply
  • [14:10:07] <prpplague> sakoman: is that a boot where you plug in the usb cable and the system boots, or is it a reset while the usb cable is plugged in?
  • [14:10:28] <sakoman> About the same for both methods
  • [14:11:18] <prpplague> sakoman: hmm, what type of host device are you plugging into?
  • [14:11:24] <sakoman> Tried 2 different host machines, generic linux box & Mac mini. Same behaviour, so not machine related
  • [14:11:28] <prpplague> sakoman: a hub or directly to a pc or laptop?
  • [14:11:33] <sakoman> direct connect
  • [14:12:09] <prpplague> sakoman: ahh, sounds kinda like a timming issue it me, we experienced something similiar with the Nail Board design
  • [14:12:14] <khasim> sakoman, it also depends on the kind of cable you are using
  • [14:12:30] <khasim> I had same issues with many cables, then found some good ones later
  • [14:12:39] <khasim> they have to shielded well
  • [14:12:50] <sakoman> well, I'm happier with the bench supply anyway. It will let me monitor power usage too
  • [14:13:00] <khasim> :)
  • [14:13:45] <sakoman> playing with the beagleboard is distracting me from the SoC driver :-)
  • [14:14:02] <sakoman> must be disciplined :-)

  • [14:32:39] <DJWillis> sakoman: you have a Beagle? Very nice :)
  • [14:33:30] <sakoman> yes!
  • [14:33:49] * DJWillis notes that poking the Pandora with a scope was keeping him from getting a working kernel sorted, that and a little 'odd' battle with OE building the wrong kernel code.
  • [14:34:03] <DJWillis> sakoman: what's the build quality like?
  • [14:34:19] <sakoman> It's very nicely done
  • [14:35:37] <DJWillis> Cool, is it one of the latest batch? (rev. B?)
  • [14:35:54] <sakoman> Though I'm kind of bothered by several components being placed at a 45 degree angle! Too many years of manufacturing folks screaming about component orientation ;_0
  • [14:36:32] <koen> Crofton: I'm fairly sure the mux driver broke ehci
  • [14:36:46] <koen> build I'm doing a non-beagle build right now, so I can't check
  • [14:37:13] <koen> CONFIG_OMAP_MUX=y
  • [14:37:27] <Crofton> I need to sort out the sffsdr kernel first
  • [14:37:36] <Crofton> hopefully this all works again later today :)
  • [14:41:46] <sakoman> DJWillis: There's a hand written "B" on the board so I assume so
  • [14:42:46] <sakoman> Got distracted watching the news -- big fire in the Santa Cruz mountains this morning
  • [14:43:06] <Crofton> sakoman, your board has a power connector then?
  • [14:43:12] <sakoman> yes
  • [14:44:17] <sakoman> Crofton: what do you use for your bootargs when booting from mmc?
  • [14:44:42] <Crofton> I forget, I'll have to check
  • [14:44:58] <koen> bootcmd=mmcinit ; fatload mmc 0:1 0x80000000 uimage ; bootm
  • [14:44:58] <koen> bootargs=root=/dev/mmcblk0p2 rootdelay=5 console=ttyS2,115200n8 noinitrd rootfstype=ext2 ip=off
  • [14:45:10] <sakoman> thanks!
  • [14:45:14] <koen> that's how I started
  • [14:45:37] <koen> I changed rootdelay to 2 (you could use rootwait with >2.6.25) and went ext3 due to reboots
  • [14:45:59] <koen> this loads uImage from FAT and boots linux from the second partition
  • [14:46:11] <koen> since u-boot 1.1.4 lacks e2load
  • [14:46:38] <sakoman> yeah, we need to build a better u-boot
  • [14:46:52] <sakoman> and get nand working
  • [14:47:06] <koen> I use dirks uboot to get L2 cache working
  • [14:47:55] <koen> which as dirk points out is the only version that actually works :(

  • [17:30:00] * koen now has https://ssl.bulix.org/projects/lcd4linux/wiki/LCD2USB working on the beagle
  • [19:12:18] <sakoman> Is it documented anywhere what nand partitioning is assumed by beagle u-boot?
  • [19:12:43] <Crofton> make something up :)
  • [19:13:00] <Crofton> well, I think you'll need to check with the bootloader people ....
  • [19:13:21] <sakoman> well, that would be dangerous because the saveenv command writes stuff to nand :-)
  • [19:13:40] <koen> doesn't uboot use the last block in flash by default?
  • [19:14:41] <ds2> uboot knows about partitioning?
  • [19:14:42] <koen> sakoman: I'd reserve a sizable chunk for the kernel partition as well
  • [19:18:45] <sakoman> koen: no on the last block
  • [19:19:11] <sakoman> typically omap boards reserve a partition for that
  • [19:19:44] <sakoman> Just need to figure out where the current u-boot writes stuff & then I'll work around that
  • [19:20:15] <sakoman> And of course I'll set things up much like the EVM and other boards partitionwise
  • [19:25:14] * koen is still wondering why omap mux improves boot behaviour but kills ehci
  • [19:49:21] <DJW|Home> koen: about? I have a really daft (I hope) question. Without any edits my Pandora OE config now trys to make kernel.org 2.6.21 rather then my GIT snapshot and I really can't figure out what I have done wrong. Any ideas?
  • [19:57:29] * DJW|Home is now known as DJWillis

  • [19:58:57] <sakoman> ah, at last: #define SMNAND_ENV_OFFSET 0xc0000 /* environment starts here */
  • [19:59:51] <koen> DJWillis: I suspect you need to your machine name to packages/linux/linux-omap2_git.bb:22:COMPATIBLE_MACHINE = "omap2430sdp|omap2420h4|beagleboard"
  • [20:01:22] <sakoman> any votes for how large to make the kernel partition?
  • [20:02:21] <theoddbot> we use 1mb for 2.4 kernels, no idea how big 2.6 is these days
  • [20:02:22] <DJWillis> koen: http://rafb.net/p/hThWp520.html << Hmm, you lost me at that point, I am using a seperate patchset in my own folder (using sakoman's older layout as an example).
  • [20:02:26] <koen> TI's .22 kernel is 2.3 MB
  • [20:02:44] <theoddbot> 3mb i guess then
  • [20:02:46] <DJWillis> sakoman: I guess 3 is safe these days.

  • [20:04:04] <koen> and try using linux-omap2_git, it works :)
  • [20:04:15] <koen> no need to reinvent the wheel ;)
  • [20:04:36] <DJWillis> so what do I need to change for that (so I dont fook up).
  • [20:05:05] <koen> PREFERRED_PROVIDER_virtual/kernel = "linux-omap3-pandora"
  • [20:05:05] <sakoman> I'll round up to 4MB for future-proofing
  • [20:05:15] <sakoman> linux seems to grow with every new rev
  • [20:05:15] <DJWillis> I guess I better move my patches over anyway (using some 2.6.24 old omap git as a base as it is 'what I had' ;-))
  • [20:05:18] <koen> DJWillis: look at beagleboard.conf :)
  • [20:05:39] <koen> sakoman: yeah, some subsystems are growing out of bounds
  • [20:05:58] <theoddbot> not like 1mb makes much of a difference on 128
  • [20:06:07] <DJWillis> koen: I'll update and see if it appears on my local tree, I could not find it last time (did I mention I am REALLY think).
  • [20:06:24] <koen> the linux-tiny people should get more vocal :)
  • [20:06:52] <koen> it has been there for 5 or 6 weeks now :)
