Summarizing RC1 tests:

The following tests failed, where I 99-run tests Task #1 and 04-single-hop-6lowpan-icmp Task #10 should be re-ran,the others are expected to fail.

Tests that were not run in RC1, here I'll investigate 04-single-hop-6lowpan-icmp Task #7 04-single-hop-6lowpan-icmp Task #6 tomorrow.

  • 04-single-hop-6lowpan-icmp Task Release 2015.09 - RC4 #7 (Experimental) - ICMPv6 multicast echo with samr21-xpro/zero + xbee, I have not been able to make xbee work, there might be an issue with our support or wiring on my side. Since this is experimental IMO not a show stopper either, but I will investigate the issue further.

  • 04-single-hop-6lowpan-icmp Task Release 2015.09 - RC5 #8 (Experimental) - ICMPv6 echo with samr21-xpro/zero + xbee. Same as above.

  • 01-ci Task [WIP] 2015.08: multi-hop test on iotlab testbed #1 - Compile test: @aabadie told me this took 5 days to run last time, maybe he can run again?

@miri64(or anyone else in Berlin) if possible could you plug and un-plug:

  • arduino-mega2560
  • ek-lm4f120xl
  • frdm-kw41z
  • mulle
  • nrf52dk

all tests failed las run on paper-ci which makes me think there is some kind of issue..

@miri64 besides 03.3 and 04.10 any other tasks that should be re-ran because of RIOT-OS/RIOT#13169 ?

No, only the tests mentioned cover that segment of code fixed in RIOT-OS/RIOT#13169.

I'll re-run:

And tomorrow tackle:

IMO only board or cpu specific fixes might still get in, and if it need arises some fix to xbee. But otherwise RC2 look good. Will wait for a second run off 99-run tests before completing.

Yes I'm using a script that sends pktbuf until empty with a timeout, so sometimes after 3sec there is still content in the buffer, but eventually it empties in the 10 runs I performed, pinging in both directions each time, so 20 executions.

Yes I'm using a script that sends pktbuf until empty with a timeout, so sometimes after 3sec there is still content in the buffer, but eventually it empties in the 10 runs I performed, pinging in both directions each time, so 20 executions.

Seems legit. The reassembly buffer timeout for IPv6 is IIRC 10 seconds.

Here is the script I used BTW, still working on it. And there are some setup requirements.

Some progress with xbee, it seems my xbee module was wrongly configured initially. I'm seeing some weird behaviour:

  • doesn't receive any packets
  • changes link local address on each packet transmitted (last 0xffff):

Sending and receiving messages when compiling examples/default works both ways.

It also answers to multicast:

This behaviour was not present in 2019.10:

Bisecting I found that RIOT-OS/RIOT#11879 broke this for xbee @jia200x @miri64 @leandrolanzieri can you help here?

To summarize with the introduction of RIOT-OS/RIOT#11879 when using xbee the source address changes at every transmition.

and tests/gnrc_netif passes.

note: there is arduino-zero+xbee on iotlab so you can reproduce.

I was trying to check that RIOT-OS/RIOT#13192 made Task #08 (Experimental) - ICMPv6 echo with samr21-xpro/zero + xbee PASS, but it isn't the case. With the ping specification in https://github.com/RIOT-OS/Release-Specs/blob/master/04-single-hop-6lowpan-icmp/04-single-hop-6lowpan-icmp.md (ping6 -c 1000 -i 100 -s 100) https://github.com/RIOT-OS/Release-Specs/blob/master/04-single-hop-6lowpan-icmp/04-single-hop-6lowpan-icmp.md it does not work, but it does with (ping6 -c 1000 -i 350 -s 100) https://github.com/RIOT-OS/Release-Specs/blob/master/04-single-hop-6lowpan-icmp/04-single-hop-6lowpan-icmp.md.

Basically increasing the packet size or reducing the interval cause it to fail after a couple of pings (os straight away), the pinger stops receiving echos and on arduino-zero I get:

2020-01-27 10:09:15,925 # gnrc_netif: netdev init failed: -5

which makes me think it hard-faulted and failed to init the netdev interface. The board needs then to be reset for it work again. I was able to reproduce the same behavior on 2019.10. I'm not sure what interval was used for this task in 2019.10 @MrKevinWeiss do you recall?

I then enabled debugging and that is exactly what is happening, continuous reboots until pinging stops or it fails to init the interface.

If I change the baudrate and ping6 -c 1000 -i 100 -s 100 there is still about %100 packet loss but no reboot is triggered, and the device is still up and running afterwards. But of course If I decrease the interval enough it doesn't withstand the stress tests.

Seems like when overstressed if it tries to send a packet it fails and then reboots.

Even if over stressed the node should still be working here so this seems like a bug to me, but I'm unsure how it's triggered, and since this is related to xbee and not upper layers (and the task is experimental), I would rather tag is at failed and focus on release notes.

If a fix is found It can be back-ported but, for now I would rather add it to known issues. If someone else is willing to dive in to this and try to fix before the Release it would be great. @aabadie @miri64 any thoughts on this, does it seem like an Ok way to go?

I'm not sure what interval was used for this task in 2019.10 @MrKevinWeiss do you recall?

I don't think it passed on the old release as it was listed experimental and it wasn't checked off.

I do remember running some interop tests with IoT labs and some nodes would have this fail to initialize and I would have to restart a bunch, @PeterKietzmann had this problem too.

It does say on an earlier task that I used a size of 50B instead of 100... maybe that was it.

Me too. I think we never mentioned it in the release notes, because the task is marked experimental and because IIRC for local tests it worked.

However, in retrospective, it might make sense to open a dedicated issue for this, even if it turns out just a problem specific to the nodes in the IoT-LAB.

I don't think it passed on the old release as it was listed experimental and it wasn't checked off.

I do remember running some interop tests with IoT labs and some nodes would have this fail to initialize and I would have to restart a bunch, @PeterKietzmann had this problem too.

It does say on an earlier task that I used a size of 50B instead of 100... maybe that was it.

I was checked on RC2:

So it seems you used 100bytes. Maybe you used the intervals that are in the example and not the spec itself.

I'll open an Issue that states everything I have described above, and mark it as failed, and move on to RC3. If I find time to investigate I'll do it before the release, otherwise it will go into known issues.

I've investigated a little more, the issue with the hardfault seems to be related to cpu/sam0_common/periph/uart.c or the interaction between it and xbee, I did the same setup with nucleo-l433rc + xbee and although the module can't handle the incoming packets at 9600 baudrate, it doesn't crash. Maybe there is an issue with xbee that shows only with some uart dirvers.

Ok, so I figured out the issue. When using an arduion breakout board CTS pin of the xbee is connected to RESET on ICPS connector, so when xbee asserts this line it causes a reset.

That might explain why I never had this issue locally. Whenever I tested with a board arduino-due, I connected its UART_DEV(1) to the breakout board's pins via jumper cable and used that UART to communicate with the board.

FYI I'm currently waiting on RIOT-OS/RIOT#13212 to open RC3 and finalize this release.
