[Linux-zigbee-devel] MRF24J40 linux driver questions.
Hello, I am starting to play with the MRF24J40 driver on a custom i.mx28 board running linux (thanks to Alan Ott for writing this driver). I assume that the WAKEUP and RESET lines are not handled by the driver, is this correct ? Also, do I just need to specify modalias, mode, irq, bus_num and chip_select in my board_info struct ? No platform_data ? Thanks for any help. -Randy -- Everyone hates slow websites. So do we.

[Linux-zigbee-devel] 'Possible recursive locking detected' on 'ifconfig lowpan0 up' .
Hello,
Hopefully this is the right list for this post, please let me know if not.
I am running linux 3.7.0-rc6 on a freescale imx28-evk dev board and am
seeing the following deadlock warning when I try to bring up the lowpan
interface via
'ifconfig lowpan0 up' . I am using the 802.15.4 radio module MRF24J40 with
corresponding driver.
Let me know if there are any fixes I can test on my board or if you need
any more info.
-Randy

[Linux-zigbee-devel] Where to pull latest source and patches.
Hello, I am new to 6lowpan and the list, so please forgive the rookie questions. Where do I download the latest source and patches ? Will this get me the latest ? I am git-challeneged but it looks like the latest commit was last year and that this may not be the most current.. git clone git://linux-zigbee.git.sourceforge.net/gitroot/linux-zigbee/linux-zigbee I see individual patches posted to the list, where are they stored ? FWIW, I am working on a custom freescale imx28 board with mrf24j40 radio and am trying to get 6lowpan running on it.

[Linux-zigbee-devel] How often is net-next merged with the mainline kernel and how to manually merge?
Hello, I would like to better understand how patches here make it into the mainline. I understand that patches here go to Dave Millers net-next repo, but when or how often do they get merged into the mainline ? Also, suppose I want to use the latest patches in net-next, how do I go about manually merging them myself into my own local kernel tree ?

Re: [Linux-zigbee-devel] How often is net-next merged with the mainline kernel and how to manually merge?
Thanks Alex, some day I hope to be able to contribute to this effort and this info is very helpful. Right now I have a 3.11 kernel that has been patched for the beaglebone (which is not mainlined) and was wondering how to patch it with the latest linux-zigbee-devel updates. I really just want to catch updates to 802.15.4 and 6Lowpan and understand how to merge and what to merge into my custom kernel tree. -Randy On Thu, Sep 26, 2013 at 4:59 AM, Alexander Aring wrote: > Hi Randy, > > On Wed, Sep 25, 2013 at 08:06:33PM -0700, Randy Graham wrote: > > Hello, > > > > I would like to better understand how patches here make it into the > > mainline. > > > Ok. > > > I understand that patches here go to Dave Millers net-next repo, but when > > or how often do they get merged into the mainline ? > > > First it's good to send the patches to this list, if somebody has > improvements, fixes or other issues you need to change that. > > After this you can send it to net-next mailinglist and David Miller > takes this patches and put it into his net-next repo(depends if all > seems ok).

Re: [Linux-zigbee-devel] How often is net-next merged with the mainline kernel and how to manually merge?
Thank you Markus. It really does seem that I need to get smarter about Git :) Do all linux-zigbee-devel patches just affect 'net' and its subdirectories or are other kernel source directories affected ?

[Linux-zigbee-devel] How to build latest net-next kernel for Ubuntu or other distro.
Hello, Is there a preferred desktop linux distro for testing net-next kernels on a amd64 desktop machine ? Ideally, I would like to run the latest net-next kernel on my Ubuntu 13.10 amd64 dev box. Are there any docs that show how to build a net-next kernel for use with Ubuntu or other preferred distro ? I tried the steps here, http://blog.avirtualhome.com/compile-mainline-kernel-ubuntu/, with net-next but compilation failed when building independent packages (fakeroot debian/rules binary-indep).

[Linux-zigbee-devel] What hardware are folks here using to test 6Lowpan on Linux ?
Hello, I am curious to know what hardware folks here are using for 6lowpan, would you mind sharing ? I am trying to get a beaglebone with a mrf24j40 radio up and running with 6Lowpan and am having some difficulties. Has anyone got this hardware combination to work with a recent kernel ? I have created a DT fragment for my radio 'cape' as per http://elinux.org/Capemgr and it loads and initializes fine with a 3.8 kernel, but when I try to use a more recent kernel, the DT fragment loads, but the IRQ reported by the mrf24j40 driver is always zero. If I use the 3.8 kernel, the driver reports a correct IRQ. Has anyone seen this issue ? Thanks for any insights. -Randy -- Rapidly troubleshoot problems before they affect your business.

Re: [Linux-zigbee-devel] What hardware are folks here using to test 6Lowpan on Linux ?
Thanks Tony. I have a couple of econotags so I'll give your driver and firmware a shot. Ultimately I want to get this running on our custom freescale board with mrf24j40 and have been using the beaglebone as a stepping stone, but getting my econotags working would also be a good step. I am running a very recent net-next kernel on my linux development machine, so hopefully I am sufficiently up to date there.

Re: [Linux-zigbee-devel] What hardware are folks here using to test 6Lowpan on Linux ?
Awesome, thanks Craig! Yes, I had changed from gpio1 to gpio2 to get it to load without errors with 3.8 . Where in the kernel does the DTS get parsed ? I'd like to look at it to understand it better. Thanks again for your help, this is gold. -Randy On Sat, Dec 21, 2013 at 4:29 AM, Craig Peacock < craig.peacock.2...@beyondlogic.org> wrote: > > Randy, > > Yes, I have seen the issue.

Re: [Linux-zigbee-devel] What hardware are folks here using to test 6Lowpan on Linux ?
Hi Tony, Thanks for your help, just one more question. Exactly what firmware do I need to flash to the econotag for use with your serial driver ? There seem to be a few images that get built under linux802154_serialdev that I could flash. -Randy On Fri, Dec 20, 2013 at 10:17 AM, Tony Cheneau wrote: > Hi Randy, > > It should work just fine with a recent net-next kernel.

Re: [Linux-zigbee-devel] What hardware are folks here using to test 6Lowpan on Linux ?
Hi Tony, I apologize if this is a repost, my previous post may have been rejected due to excessive length, so I'll keep this short :) I have flashed my econotag and patched and installed the serial driver per this thread but am seeing this error when I run set-serial.sh. Traceback (most recent call last): File "/sbin/set-econotag.py", line 75, in cn = DQ(sys.argv[1],baudrate=921600) TypeError: __init__() got an unexpected keyword argument 'baudrate' Hopefully this points to an obvious issue with my setup, do you have any thoughts ? I can attach logs of my terminal session and dmesg output if that helps. Thanks for any insights you may have into this. -Randy -- Rapidly troubleshoot problems before they affect your business.
