Hi Tim,

As I say here, the CC1352P7 on the BeaglePlay is always wired to /dev/ttyS4: https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz-group/sub-1-ghz/f/sub-1-ghz-forum/1240525/faq-cc1352p7-is-ti-wisunfantund-working-with-the-newly-released-beagleplay-yes

Hello Arthur,

The CC1352P7 serial port has been moved to ttyS2 in the newest BeaglePlay OS with kernel v6.6.

Hi Tim,

Is the same happening when using only the "--play" option? https://github.com/beagleboard/cc1352-flasher

Regards,

Arthur

This command turns out this way:

debian@BeaglePlay:~$ cc1352_flasher -v --play -p /dev/ttyS2
Traceback (most recent call last):
File "/usr/local/bin/cc1352_flasher", line 8, in <module>

Hi Tim,

Is it also failing when you do not specify the UART port?

Regards,

Arthur

also bad output:

Hello Arthur,

Is there any chance to repair it?

Hi Tim,

I have to try it myself. You can expect an answer on Monday, as I have to upgrade my BeaglePlay to the latest version.

Regards,

Arthur

Thank you, Arthur.

I hope we can repair it by next week.

I have bought an huge antenna to be ready for field experiment over a small hill in my area.

Hi Tim,

The problems goes much further. It seems like the Beagle developers removed the bcfserial for some reason:

• https://git.beagleboard.org/beagleboard/BeagleBoard-DeviceTrees/-/merge_requests/67/diffs
• https://git.beagleboard.org/beagleboard/BeagleBoard-DeviceTrees/-/merge_requests/69/diffs#207dd9ca4ec7c1ea383276671052c3b4c64b5861

I am then trying to recompile the latest device trees: https://git.beagleboard.org/beagleboard/BeagleBoard-DeviceTrees/-/tree/v6.12.x-Beagle, where UART6 is enabled, but it does not seems to work yet, even though I replaced the existing .dtbs with the newly compiled ones.

If you want, it could be great if you brought that up on the beagleboard.org forum.

Regards,

Arthur

I see!

I have reflected this problem already on BeaglePlay.  I think I had better downgrade to kernel v5 and check this again.

Hello Arthur,

I switch to kernel v5 with

sudo apt install bbb.io-kernel-5.10-ti-k3-am62
sudo reboot && exit

Bad news is - it is also affected and there is no more connection to the on board CC1352P7.  BeaglePlay Team are the one who make BeaglePlay very unstable!  Stability maintenance is so bad!

Hi Tim,

For the time being then, I recommend you to stay on Debian 11.7. This is the version that I also use.

We will see what the BeaglePlay team has to say.

Regards,

Arthur

Arthur, okay then.

The older BeaglePlay OS Debian 11.7 only has a GUI desktop version.

How do we remove all those desktop related elements?

I hope there is the least software to interfere with Wi-SUN stack.

Hi Tim,

Seems like there is a minimal Debian 11.x distribution there: https://forum.beagleboard.org/t/arm64-debian-11-x-bullseye-monthly-snapshots-2023-10-07/32318

Hello Arthur,
I have built a new BeaglePlay based on your recommended image.  Then, I got this report from my terminal interacting with the on-board CC1352P7.  Does it imply that I did it correctly?

Hi Tim,

It indeed seems like the onboard CC1352P7 has been flashed correctly. This is good news.

Regards,

Arthur

WOW!  I have my TI wi-sun network up again with all the correct parameters! 

1. On the other hand, how do we tune log records from within the file /etc/wpantund.conf so that we can monitor a running production grade TI Wi-sun border router?
2. As to the BeaglePlay Debian OS 11.8, there is no Linux SWAP partition assigned.  Does it hurt system stability?

Yours faithfully,
Timmy

Hi Tim,

1. What do you want to achieve exactly? Do you just want a way to store your log files with as much information as possible somewhere?

2. There is probably a reason behind that choice made by the BeagleBoard people. You can ask them on their forum.

Regards,

Arthur

Hi Arthur,

Yes, I want to store more details logging of the Wi-SUN stack particularly the wfantund, its interaction with the Wi-SUN web app, etc.

So I can investigate it when it will crash the next time.

Hi Tim,

For the time being, you could probably just redirect the TI wfantund output to a log file using ready available tools.
As of the border router, given that you are using the BeaglePlay, it seems like we do not have access to an extra UART that we could use to output other log states, without a hardware modification of course.

Regards,

Arthur

Hi Arthur,

I added this line in file /etc/wpantund.conf

Daemon:SyslogMask "all"

and then restarted wfantund.  Then, I issued

debian@BeaglePlay:~$ dmesg | grep wpantund
debian@BeaglePlay:~$ dmesg | grep wfantund
debian@BeaglePlay:~$ dmesg | grep wfan
debian@BeaglePlay:~$ dmesg | grep tun
[  189.460178] tun: Universal TUN/TAP device driver, 1.6

I only got very little information from the syslog provided.

I got these extra information with my friend's start up script:

debian@BeaglePlay:~$ journalctl -u wisun-br.service -b
-- Journal begins at Mon 2024-11-25 23:56:29 HKT, ends at Tue 2024-12-03 00:58:37 HKT. --

Dec 03 00:41:33 BeaglePlay wisun-br[736]: /usr/local/bin/wisun-br: line 20: gpioget: command not found

I think I have got too much information now with this line!

I added this line in file /etc/wpantund.conf

Daemon:SyslogMask "all"

I have found that this one may be helpful when the next time my border router crashes:
