May 11 14:00:20 <CoffeeBreakfast> hello
May 11 14:05:58 <CoffeeBreakfast> any recommendations for a blog, for posting BBB projects?
May 11 14:08:37 <tbr> any blog will do IMO. If you looking for a hosted "community", I guess the hackaday stuff might be a place?
May 11 14:17:32 <CoffeeBreakfast> Could be blogger, meh.. but I suppose hackaday is the kind of blog I prefer.
May 11 21:28:10 <black_13> I have built a beagle image using yocto what next that is how do i get the items in the TMPDIR to flashdrive and then boot?
May 11 21:28:39 <zmatt> sounds like a question for #yocto
May 11 21:29:37 <zmatt> (btw I assume you meant "sd card" and not a usb flash drive, since the bbb doesn't boot from those)
May 11 21:31:02 <zmatt> also, you should probably wipe the eMMC of the bbb, e.g. by booting from an sd card containing an official debian image and then performing the command "sudo blkdiscard /dev/mmcblk1"
May 11 21:31:44 <zmatt> this ensures that the bbb will load the bootloader (u-boot) from sd card rather than from eMMC, which could be incompatible with yocto
May 11 21:32:47 <zmatt> alternatively you can bypass the eMMC bootloader by holding down the S2 button while powering on the BBB.  You can let go once the power led turns on, and its effect is persistent across reboot/reset (it is only sampled at power-on)
May 11 21:36:48 <zmatt> (instead of pressing the S2 button you can also connect a resistor in the range 1K-10K between P8.43 and ground. this is also safe to leave in place, and probably the most convenient way to force sd-boot if you frequently power-cycle the bbb but don't want to wipe eMMC)
May 11 21:38:36 <black_13> zmatt: you are correct sd card
May 11 21:39:06 <black_13> and beagle as far as i undertand does boot rom and sd card if the s2 button is head down ... correct
May 11 21:39:47 <black_13> where is P8.43
May 11 21:40:20 <zmatt> https://beagleboard.org/static/images/cape-headers.png
May 11 21:40:56 <zmatt> you really shouldn't have to ask a question like that if you're working with advanced stuff like yocto :P
May 11 21:45:50 <black_13> zmatt: that is not a comment about beagle or yocto
May 11 21:46:17 <zmatt> ?
May 11 21:48:49 <zmatt> as for the boot process: in the default configuration, bootrom will try to load u-boot from { eMMC, μSD, uart0 (xmodem), usb0 (rndis) } in that order.  If the S2 button is held down (or P8.43 is otherwise pulled low) during power-on, the boot order changes to { spi0, μSD, usb0 (rndis), uart0 (xmodem) }
May 11 21:50:08 <black_13> usb0 (rndis) is loading over the usb cable?
May 11 21:50:57 <zmatt> the behaviour of u-boot will vary depending on how it is built, but the one used in beagleboard.org images will try to load linux from SD card first and then eMMC.  I don't know if it is compatible with linux images other than the beagleboard.org debian images
May 11 21:51:28 <black_13> I had been making images for a toradex board
May 11 21:51:52 <zmatt> usb0 is the mini-USB port, and with rndis I mean it appears as an rndis network device to the host, and bootrom will then attempt to netboot via that network interface
May 11 21:51:55 <black_13> and had that working but i have left that job and had some bbb that i ended up with
May 11 21:52:11 <black_13> i figured if made a mistake what is the worst i could do
May 11 21:52:55 <black_13> zmatt: ah so this would be a kind of TFTP boot using rndis
May 11 21:53:11 <zmatt> yes
May 11 21:53:19 <black_13> that could be interesting
May 11 21:54:19 <zmatt> the bbb can also tftpboot via ethernet.  if sysboot2 (P8.43) is pulled low and sysboot0 (P8.45) is pulled high then the boot order becomes { spi0, μSD, ethernet, uart0 }
May 11 21:55:28 <zmatt> in both cases you'd need a custom-built u-boot with the appropriate mechanism (ethernet or usb rndis gadget) enabled in SPL to allow 2-stage loading of u-boot via TFTP
May 11 21:55:32 <black_13> handy then you just need to solder a resitor with long leads
May 11 21:56:11 <black_13> does matt malloy's book talk about this
May 11 21:56:23 <zmatt> yeah I'd make jumper wires with an inline resistor, especially since resistor leads may be too thin to make proper contact
May 11 21:57:26 <zmatt> you can also just use wires if you make sure that the pins won't be configured as outputs by the system that you're booting.  the default images from beagleboard.org do configure them as outputs however
May 11 21:57:27 <black_13> what is the correct way to partition the sd card i am following instructions from https://jumpnowtek.com/beaglebone/BeagleBone-Systems-with-Yocto.html
May 11 21:57:55 <zmatt> I don't know anything about yocto, sorry
May 11 21:58:13 <black_13> i take it then you are just using debian then
May 11 21:58:19 <zmatt> correct
