Linux: WL1835MOD meshpoint mesh gets jammed

Hi Paul.
Can you pls elaborate on following

"We have solved one issue: we can keep the mesh stable if nothing happens in the mesh."
How did you fix this issue ?

"We tried the buildscript described in processors.wiki.ti.com/.../WL18xx_System_Build_Scripts but these scripts doesn't work anymore. "
I believe you are running the script on kernel 4.0.x - if yes, the scripts should run ok

I recommend using build scripts and updating hostap/wpa_supplicant , driver modules etc. since they carry most mesh related mods

Saurabh

Hi Saraubh

Your Question: How did you fix this issue ?

We changed the kernel. I came on the Processor SDK on your website: http://software-dl.ti.com/processor-sdk-linux/esd/AM335X/latest/index_FDS.html  Processor_SDK_Linux_Release_Notes" There I found this kernel: 

Linux Kernel

The kernel git repository, branch and commit id can be found below:

Based on Version: 4.9.69

URL: git://git.ti.com/processor-sdk/processor-sdk-linux.git

Branch: processor-sdk-linux-04.03.00

Commit ID: bfe793963ed7b2af3e1c3dd32e7275f449e6259d

By using this kernel we arrived for the first time at a stable mesh.

Concerning the build script: there are errors in it. Some repos in the script are not existing. But we could get the other data from teh script, the version of hostap, crda, uim, the frimware and the target scripts. We used the driver from the kernel, the kernel 4.9.69.

Other data you ask:

Host platform: Beaglebone Black Wireless

OS: Linux - Yocto build system

Wilink flavor: I think WL1835MOD, the device on the Beaglebone Black Wireless

Wilink driver version: wlcore: PHY firmware version: Rev 8.2.0.0.240 , wlcore: firmware booted (Rev 8.9.0.0.76),  wlcore: wl18xx HW: 183x or 180x, PG 2.2 (ROM 0x11), srcversion=B5F5593DBBBCB67CCC10F7F

Wilink software version: R8.7

Firmware version: 

FRev 8.9.0.0.76
FRev 8.2.0.0.240

When booting we also see this error: wl18xx_driver wl18xx.0.auto: Direct firmware load for ti-connectivity/wl1271-nvs.bin failed with error -2 . I don't know what this means.

 

When I look at the strings from the Wilink driver version I see a lot of errors, does that mean anything special?:

Hope you can help us with this issue.

Thank you.

Hi Paul,
"Concerning the build script: there are errors in it. Some repos in the script are not existing. But we could get the other data from teh script, the version of hostap, crda, uim, the frimware and the target scripts. We used the driver from the kernel, the kernel 4.9.69."
Build scripts do not support backports for kernel 4.9 - you will see error when it tries to build kernel modules against 4.9.x kernel. Everything else should build ok .

"When booting we also see this error: wl18xx_driver wl18xx.0.auto: Direct firmware load for ti-connectivity/wl1271-nvs.bin failed with error -2 . I don't know what this means."
For now you can ignore this but fix it for final product. This file consists of MAC addresses for WiFi/BT interfaces. Absence of this file will not limit driver functionality .

We tested mesh with kernel 4.4 . SDK kernel 4.9 is missing mesh related patches resulting in some issues. We are aware of this issue and currently evaluating how we can address it .

Thanks
Saurabh

Thank you Saurabh for your answer, but can you please say in more detail what kernel you have used. Is it from the repo: 

git://git.ti.com/processor-sdk/processor-sdk-linux.git

or from the repo: git://git.ti.com/wilink8-wlan/wilink8-wlan-ti-linux-kernel.git ?

And what is the branch or the tag?

We would have the commit that you say that works. Is this possible. Thank you.

Hi Paul,
We tested it on kernel 4.4
git://git.ti.com/wilink8-wlan/wl18xx.git
branch : upstream_44, tag R8.7_SP3

Thanks
Saurabh

Saurabh
Thank you for this quick answer. I will test our build with this kernel. Does this kernel also compiles for an iMX6 processor. Probably yes, but do you know of tests for iMX6?
Thank you.
Paul Becue.

Hi Paul,
We are not running tests on IMx6 at our end . build-utilties do have iMx related kernel patches that you can refer to .

Saurabh
