Jun 23 09:19:00 <vvu> av500: ping
Jun 23 09:27:03 <vvu> av500: when you have time please take a look at https://github.com/ungureanuvladvictor/BeagleDroid/blob/master/BeagleDroid/src/main/java/com/vvu/beagledroid/MainActivity.java
Jun 23 09:27:41 <vvu> i implemented device_filter, when the BBB is attached to the android device the app starts itself and permissions are granted automatically.
Jun 23 09:28:47 <vvu> the only problem is at line 60, at the bulk transfer. it just hangs there, like the board is not sending anything. i checked the endpoint to see the direction of the transfer and it is device->host(IN directon).
Jun 23 10:17:56 <vvu> alo tried to do it in a separate thread than main one same result.
Jun 23 14:08:40 * vvu tries to find some android people around
Jun 23 17:09:56 <keesj> doing IO in the main loop is not great indeed. you need to create a "service" or  thread isn't there some known sample code?
Jun 23 17:20:11 <vvu> keesj: did in a separate thread
Jun 23 17:20:13 <vvu> same result
Jun 23 17:20:43 <vvu> keesj: http://pastebin.com/V1Bf1sjr
Jun 23 17:22:45 <vvu> it is the same for send or receive *changed endpoint*, just stalls there. and i checked the dmesg the BBB is seen correctly.
Jun 23 18:05:56 <gregkh> ZubairLK: now I am, get it all working again?
Jun 23 18:06:19 <ZubairLK> yup. thankfully :)
Jun 23 18:06:29 <gregkh> ZubairLK: nice.
Jun 23 18:06:43 <ZubairLK> is there a better way than tftp the kernel uImage file?
Jun 23 18:09:14 <gregkh> ZubairLK: i don't know of one, sorry.
Jun 23 18:09:25 <ZubairLK> its ok. seems to work pretty well
Jun 23 18:11:29 <ZubairLK> gregkh: I can't seem to find a way to remove a device overlay. do i need to reboot everytime and apply another?
Jun 23 18:14:06 <gregkh> ZubairLK: I think so, I have no experience with them.  People are working on dynamic overlays, but that code hasn't been merged yet.
Jun 23 18:14:35 <ZubairLK> I see. I'll stick with restarting for now. emmc makes it boot much faster
Jun 23 18:15:59 <keesj> vvu: line 55 is lacking a "="
Jun 23 18:16:38 <keesj> no
Jun 23 18:18:55 <keesj> did you read http://developer.android.com/guide/topics/connectivity/usb/host.html (the part about permissions ?)
Jun 23 18:20:10 <keesj> I did something like https://github.com/keesj/android-rtlsdr/blob/master/src/rtlsdr/android/MainActivity.java#54
Jun 23 18:24:45 <keesj> note that this code used the same Thread approach (I didn't take the time to make it work properly at the signals obtained where looking really weird
Jun 23 18:28:30 <vvu|Mobile> keesj when we have a device filter aren't permissions granted automatically?
Jun 23 18:31:49 <keesj> try it
Jun 23 18:32:14 <vvu|Mobile> I can open the device so i have permissions
Jun 23 18:34:34 <vvu|Mobile> Also i have read the host documentation and followed those steps
Jun 23 18:52:39 <jj2baile> ka6sox: any idea of reasons why the pru driver would fail to open/
Jun 23 18:52:56 <jj2baile> is loading uio_pruss via 'modprobe uio_pruss'
Jun 23 18:52:59 <jj2baile> the only thing you need to do?
Jun 23 18:53:34 <ZubairLK> koen:
Jun 23 18:53:37 <ZubairLK> gregkh
Jun 23 18:53:39 <ZubairLK> or anyone else :)
Jun 23 18:53:41 <ZubairLK> Any kernel I compile and tftpboot myself  results in missing usb0 entries 192.168.7.2 ..
Jun 23 18:53:45 <ZubairLK> If i load the uImage-dtb-am335x-boneblack file. I manage to tftp boot. but no usb0 (dont need it. but i'm trying to replicate the stock kernel functionality first)
Jun 23 18:53:49 <ZubairLK> Even if I try to load the uImage file that came with the bbb.
Jun 23 18:53:51 <ZubairLK> TFTP boot doesnt work and gives  Error: unrecognized/unsupported machine ID (r1 = 0x00000e05).
Jun 23 18:53:55 <ZubairLK> uEnv is
Jun 23 18:53:57 <ZubairLK> optargs=quiet drm.debug=7
Jun 23 18:54:01 <ZubairLK> ipaddr=192.168.0.250

Jun 23 18:54:17 <ZubairLK> Toolchain could be code sourcery  or the one OE generates
Jun 23 18:54:19 <ZubairLK> but i'm not sure as  i have confused them up and dont remember which folder I compiled with which toolchain
Jun 23 18:56:20 <gregkh> ZubairLK: I don't know, sorry.
Jun 23 18:56:39 <ZubairLK> its more of a BBB question than a kernel question :)
Jun 23 20:02:57 <_av500_> ZubairLK: that error seems to be toolchain related
Jun 23 20:03:04 <_av500_> koen mentioned something like that
Jun 23 20:03:09 <_av500_> so please use the angstrom toolchain
Jun 23 20:03:12 <_av500_> node code sourcery
Jun 23 20:03:40 <ZubairLK> i see. but I'm unable to boot the uImage that came with the BBB via tftpboot.
Jun 23 20:03:50 <ZubairLK> the ones i compile myself can be booted via tftp..
Jun 23 20:04:15 <ZubairLK> or are we talking about the missing usb0 stuff? :s
Jun 23 20:04:29 <ZubairLK> _av500_:
Jun 23 20:06:01 <_av500_> hmm
Jun 23 20:06:09 <_av500_> so what do you get with the supplied uimgae?
Jun 23 20:06:12 <_av500_> what error?
Jun 23 20:31:17 <ZubairLK> Error: unrecognized/unsupported machine ID (r1 = 0x00000e05)
Jun 23 20:31:38 <ZubairLK> _av500_:  I get the above if I use the stock uImage3.8.13 with the stock uboot and try to tftp it
Jun 23 20:31:52 <ZubairLK> uEnv is
Jun 23 20:31:54 <ZubairLK> optargs=quiet drm.debug=7
Jun 23 20:31:58 <ZubairLK> ipaddr=192.168.0.250

Jun 23 20:32:04 <ZubairLK> #uenvcmd=run loaduimage run loadfdt run mmcargs bootz 0x802800000 - 0x80F80000
Jun 23 20:32:07 <_av500_> and the dt?
Jun 23 20:32:08 <ZubairLK> bootargs=console=ttyO0,115200n8 root=/dev/mmcblk0p2 ro rootfstype=ext4 rootwait
Jun 23 20:32:10 <ZubairLK> uenvcmd=echo "Booting from Network";tftpboot 0x80200000 uImage; bootm 0x80200000
Jun 23 20:32:18 <_av500_> you need to supply the DT
Jun 23 20:32:25 <ZubairLK> aha
Jun 23 20:32:29 <_av500_> you just load uimage over tftp
Jun 23 20:32:30 <ZubairLK> and what/where do i do that?
Jun 23 20:32:31 <_av500_> not the DT
Jun 23 20:32:39 <_av500_> same as uimgae
Jun 23 20:32:40 <_av500_> sec
Jun 23 20:32:57 <ZubairLK> so the uImage-dt-beagleblack that I compile myself already has a dt in it?
Jun 23 20:33:04 <_av500_> loadtftp=tftpboot $fdtaddr /boot/am335x-bonelt.dtb ; tftpboot $loadaddr /boot/uImage
Jun 23 20:33:07 <_av500_> ZubairLK: maybe
Jun 23 20:33:12 <_av500_> appended DT is one way
Jun 23 20:33:22 <ZubairLK> thanks!
Jun 23 20:33:25 <ZubairLK> lemme try this
Jun 23 20:33:37 <_av500_> you need to adapt to your setup
Jun 23 20:33:43 <_av500_> but basically your tftp both
Jun 23 20:33:46 <_av500_> DT and kernel
Jun 23 20:33:52 <_av500_> to two different addresses
Jun 23 20:33:57 <_av500_> that you both pass to bootm
Jun 23 20:34:08 <_av500_> but that is same for SD or tftp
Jun 23 20:34:10 <ZubairLK> how to pass second address to bootm
Jun 23 20:34:17 <_av500_> see the stock
Jun 23 20:34:18 <_av500_> script
Jun 23 20:34:36 <_av500_> bootcmd=echo TFTP/NFS boot ...; run loadtftp; run nfsargs; bootm ${loadaddr} - ${fdtaddr}
Jun 23 20:34:50 <_av500_> see ^^^
Jun 23 20:34:53 <ZubairLK> ah
Jun 23 20:35:04 <ZubairLK> i'd see but not observe :p
Jun 23 20:35:09 <ZubairLK> now i understand :)
Jun 23 20:35:11 <ZubairLK> thank-you very much
Jun 23 20:36:06 <_av500_> np
Jun 23 20:40:35 <ZubairLK> _av500_: it works!
Jun 23 20:41:18 <ZubairLK> _av500_: now for the missing usb0 on my kernels..
Jun 23 20:41:23 <ZubairLK> is it toolchains?
Jun 23 20:41:35 <ZubairLK> which toolchain does everybody use
Jun 23 20:42:43 <ZubairLK> http://www.angstrom-distribution.org/toolchains/angstrom-eglibc-i686-armv7a-vfp-neon-v2012.12-toolchain.gz
Jun 23 20:42:46 <ZubairLK> ?
Jun 23 20:43:09 <ZubairLK> or some linaro one?
Jun 23 20:44:17 <ZubairLK> or MACHINE=beaglebone ./oebb.sh bitbake meta-toolchain
Jun 23 20:45:59 <vvu> keesj: tried with the permissions usbmanager.haspermissions and i have them
Jun 23 20:46:12 <vvu> now i totally don`t have any clue what to do anymore
Jun 23 20:46:43 <vvu> _av500_: any idea how i can debug more the app?
Jun 23 21:08:01 <ZubairLK> koen:  Does the following make the best toolchain?
Jun 23 21:08:03 <ZubairLK> MACHINE=beaglebone ./oebb.sh bitbake meta-toolchain
Jun 23 21:08:17 <ZubairLK> kernel/uboot/applications. I want to be toolchain worry free. which one do you use?
Jun 23 21:11:19 <_av500_> vvu: tomorrow
Jun 23 21:11:24 <vvu> okei
Jun 23 21:27:20 <vvu> i did MAGIC and it worked!
Jun 23 21:28:49 <ZubairLK> vvu: +1 :)
Jun 23 21:29:48 <vvu> thx!
Jun 23 21:32:36 <vvu> keesj: _av500_ i always tried to read using timeout 0, now changed like http://pastebin.com/FehnfpKE and it works
Jun 23 21:32:37 <_av500_> vvu: please tell
Jun 23 21:32:53 <_av500_> aha
Jun 23 21:33:33 <vvu> can`t explin why, but happy i can read
Jun 23 21:33:47 <_av500_> good
Jun 23 22:11:32 <ka6sox> back
Jun 23 23:41:41 <jj2baile> Hmm
Jun 24 02:49:57 <jj2baile> So, What is a good way to debug a kernel module
