May 31 07:27:04 <avrelaun> Hi, did CircuitCo stopped BBB production ?
May 31 07:40:20 <w0lf1cly> hi
May 31 07:45:49 <shu_> anybody here?
May 31 07:46:25 <shu_> my tpm can't create EK,who can help me?
May 31 07:51:01 <shu_> who can tell me what's wrong with my tpm
May 31 07:51:06 <shu_> Tspi_TPM_CreateEndorsementKey failed: 0x00000008 - layer=tpm, code=0008 (8), The                                       TPM target command has been disabled
May 31 07:56:23 <zmatt> shu_: I'm prettu sure that command is normally not available
May 31 07:58:01 <shu_> what should I do
May 31 08:01:03 <zmatt> the EK is normally already present in a TPM (although this may vary depending on manufacturer and exact part code ordered)
May 31 08:01:26 <zmatt> unless specifically created to be revocable it is permanent
May 31 08:03:12 <shu_> if I recocable,I can get again?
May 31 08:03:39 <shu_>  if I revocable,I can get again?
May 31 08:03:44 <zmatt> do you even understand what the EK is?
May 31 08:03:50 <shu_> yes
May 31 08:06:43 <zmatt> if the EK is revokable and you have the revocation key then you can issue a TPM_RevokeTrust to clear the EK (and this implicitly clears ownership as well, if taken); asserting physical presence is required
May 31 08:07:52 <zmatt> if that succeeds you can command the TPM to generate a new EK (it would be wise to generate a revocable one again, otherwise the action is irreversible) and then proceed to take ownership
May 31 08:09:55 <shu_> ok,thanks
May 31 08:11:00 <shu_> another question is that I can't cat my pubek
May 31 08:11:40 <shu_> when I cat pubek,there is nothing came back
May 31 08:13:15 <shu_> and I got it once
May 31 08:14:14 <zmatt> once you've taken ownership the TPM_ReadPubek command (which requires no authorization) no longer works, although there's another command which requires owner-authorization which should work
May 31 08:16:10 <shu_> if that,how can I use the pubek to encrypt
May 31 08:17:03 <zmatt> the ek is never used for encryption afaik
May 31 08:19:00 <shu_> I know,I mean using public key
May 31 08:21:10 <shu_> I want use pubek to encrypt,my tpm-tools hasn't tpm_bind
May 31 08:28:05 <zmatt> the EK is only used for specific TPM purposes, it cannot be used for general-purpose encryption
May 31 08:28:14 <zmatt> afaik
May 31 08:29:18 <shu_> you are correct
May 31 08:32:08 <shu_> there isn't tpm_bind,if I write it,it's too difficult，can you help me?
May 31 08:32:40 <shu_> what should I do can bind
May 31 08:33:50 <zmatt> a quick google right away found examples -> https://www.cylab.cmu.edu/tiw/slides/challener-handout.pdf
May 31 08:34:19 <zmatt> it has chapters on binding and unbinding data
May 31 08:34:59 <shu_> ok,let me have a look,thank you very much
May 31 08:39:55 <zmatt> I think you can also use libengine-pkcs11-openssl to allow openssl to use the TPM
May 31 08:40:01 <avrelaun> Hi, did CircuitCo stopped BBB production ?
May 31 08:42:29 <shu_> ok
May 31 08:43:00 <zmatt> avrelaun: dunno, does it matter? element14 still produces it
May 31 08:44:56 <avrelaun> zmatt: I'm just curious
May 31 09:01:17 <zmatt> shu_: https://github.com/ThomasHabets/simple-tpm-pk11
May 31 09:01:23 <zmatt> possibly also of interest
May 31 09:18:37 <shu_> if I use openssl,I have to know where is my rsa-key made by tpm,I can't find them.
May 31 15:07:44 <citylight2> hi, I am looking to log a flow sensor using the BBB
May 31 15:08:27 <citylight2> I want to write to a RAM based file and have it periodical saved to flash to reduce flash writes
May 31 15:08:34 <citylight2> how to do this?
May 31 15:34:50 <goweropolis> Looking for some assistance or shared experience.  I've had a BBB for quite a while and it was working fine running Debian Wheezy off the eMMC as a file server.  We recently had a power outage, after which I couldn't boot it anymore.  I reflashed the eMMC from the SD card using an official image, and I restarted and could run off the eMMC for a while.  I installed programs, changed configuration; everything seemed to be running OK. 
May 31 15:36:10 <goweropolis> when I tried to reboot (either through CLI or unplugging/pluggin in the power cord), it would not book.  The far right LED would do a steady heartbeat flash and nothing comes up.  I tried a few different Debian Jessie images, and same thing each time.
May 31 15:36:49 <goweropolis> Anyone have any thoughts on what the issue could be?  Could it be something I'm installing on the eMMC; I usually install logitechmediaserver for my Squeezebox.
May 31 15:38:33 <Ragnorok> My standard thought on random boot issues is use the serial console header and see if it says what's happening.
May 31 15:41:44 <goweropolis> Thanks ragnorok.  I've never connected via serial cable before.  I'll have to figure that out.
May 31 15:42:21 <Ragnorok> If you have a FTDI or a CP2102 it should work.  There's info on the 'net that's not hard to find.
May 31 15:44:43 <citylight2> does the emmc provide a SMART interface to know when the flash is worn-out?
May 31 15:45:36 <goweropolis> Yeah, looks like I need to get myself an FTDI cable then test my troubleshooting skills.
May 31 15:50:46 <Ragnorok> citylight2: Not that I'm aware of.
May 31 15:53:52 <Tom__> hello
May 31 18:01:52 <txt-file> A big thank you to the website creators that the BB web site is also usable without JavaScript.
May 31 19:30:01 <Wayne_> I have 4 beagle bone black devices.  One of them is running Cloud9 GNOME Image 2013.09.04 with can0 enabled.  I would like to duplicate this on the others.  I am using a Mac OS X machine to download images and ssh into the one device (BBB1)
May 31 19:32:08 <Wayne_> I found several places where there are instructions on how to perform the flash operation and several of them suggest using the SDFormatter_4.00B.  I downloaded and ran the application.  When I select the option to overwrite everything it seem like it will take WAAAYYYY too long.  Is there any suggestions on a way the is acceptable and will not take overnight to complete?
May 31 20:47:08 <ScrumpyJack> Wayne_: i take it your image isn't on the SD card but on the eMMC?
May 31 20:47:44 <ScrumpyJack> if it's on an SD card, use dd from one card to another
May 31 23:49:54 <bengardiner> hi all
May 31 23:54:41 <bengardiner> I'm attempting to us the GPMC for an external parallel-bus peripheral. I've booted from SD, added the disable HDMI and disable eMMC device tree overlays. But... my peripheral needs the reset pin which is claimed by rstctl.4. Making an overlay that sets that node's status = "disabled" doesn't seem to have the desired effect of freeing the pin I want. echoing
May 31 23:54:42 <bengardiner> the platform bus address to .../unbind freezes the system. Is there any other way to free this pin other than booting a modified dtb?
