Issue about IP configuration

sb10q

Alto_O I suspect the problem is that our lab network has IPs 10.194.10.155/24 and the device is placed outside the lab network. Does this matter, and any prescriptions for this issue?

Yes, it matters. Change the IP address of either Kasli or the network it is connected to.

Alto_O

Thank you for the reply. I must be dumb but changing the IP address of Kasli means changing the one written in device_db.py. right? I also wonder which device_db.py is to be done.

sb10q

You need to change it both in device_db.py and in the Kasli's flash, using either artiq_coremgmt or artiq_mkfs + artiq_flash. Search the manual for these keywords.

Alto_O

Thank you for answering to my dummy questions, problems are now fixed!

Alto_O

Now I am able to change Kasli's IP address and "artiq_coremgmt log" command works with output:

[6.518991s] INFO(runtime): network addresses: MAC=----- IPv4= changed IPv4 address IPv6-LL= some adress IPv6=no configured address.

Now "ping Kasli's IP address" works as well and am trying to run led.py indicated in the tutorial.
But any led does not glow and "artiq_coremgmt log" command says

[ 1326.394932s] INFO(runtime::session): new connection from My PC's IP address:60580
[ 1326.432932s] INFO(runtime::kern_hwreq): resetting RTIO
[ 1326.439299s] INFO(runtime::session): no connection, starting idle kernel
[ 1326.445391s] INFO(runtime::session): no idle kernel found

Again this might be a stupid question but what is the problem here?

The log looks fine. If the LED does not light up, that's probably because you have the wrong channel in your device database.

Alto_O

It is now clear that, as you pointed out, I have wrong channels in the device database. I tried to make all the TTL blink and only the IO5 port on SMA-DIO board works, but was working as "ttl1" which seems to be assigned to IO2 port if properly worked. I can rewrite the channel for this IO5 port but others are missing. The code is as below. Is there any way to find correct channels of unfound lines?
device_db.py has not been changed since it arrived us in the USB, other than the IP address.

Use artiq_sinara_tester for testing your system. Your code looks strange and the indentation is definitely incorrect.

Alto_O

Thanks, and excuse me for pasting the code without indentaitons.

As my conda environment did not possess artiq_sinara_tester.py, I made a copy and run it with outcomes:

Urukul is definitely not working? and LEDs, TTL outputs and inputs all failed (but the program proceeded by pressing enter key).

sb10q

Alto_O Urukul is definitely not working?

Where did you purchase your system from?

TTL outputs and inputs all failed (but the program proceeded by pressing enter key).

Did you pay attention to instructions such as "Connect ttl4 to ttl0"?

Alto_O

sb10q I purchased Kasli+Urukul+SMA-DIO system from M-labs through Sankyo-densei (2-12-9 Taito, Tokyo, Japan).

Did you pay attention to instructions such as "Connect ttl4 to ttl0"?

Yes, IO4 port on the SMA-DIO board is connected to IO0 port (is that corect?).

sb10q

Alto_O Yes, IO4 port on the SMA-DIO board is connected to IO0 port (is that corect?).

Yes.

During the LED test, the two LEDs next to the bottom two SFP ports should be blinking. Are they? If not, there is most likely a problem with the device database.
