Almazny v1.2 Help

kvziegler

Hi,

My Almazny v1.2 does not output anything when testing with artiq_sinara_tester. The Mirny v1.1.1 does as expected. Attached is the output of both the Mirny and the Almazny via the artiq_sinara_tester.

Any help is greatly appreciated. Thank you.

kvziegler Probably your almazny was mistakenly written as an older one. Check the JSON and the device_db. In JSON it should be "almazny_hw_rev": "v1.2", and in device_db there should be AlmaznyChannel classes.
Also, you may want to regenerate the device_db file with artiq_ddb_template command.

Hi,

I regenerated my device_db and double checked that the JSON specified "almazny_hw_rev": "v1.2". My device_db does indeed include the AlmaznyChannel classes (see attached device_db.py). I'm am getting the same blank result when testing via the artiq_sinara_tester -o almaznys.

I think the problem lies in the fact that I haven't re-flashed the firmware with the Mirny 0.3.1 firmware as specified on the internal support page: https://git.m-labs.hk/sinara-hw/assembly/src/branch/master/src/hw/mirny_almazny.md.

I have cloned the latest stable artiq repo (release 8.0) and added,

`iseEnv = pkgs.buildFHSEnv {
name = "ise-env";
targetPkgs = vivadoDeps;
};

ise = pkgs.buildFHSEnv {
name = "ise";
targetPkgs = vivadoDeps;
profile = "set -e; source /opt/Xilinx/14.7/ISE_DS/settings64.sh";
runScript = "ise";
};`

to the flake.nix. Am I taking the correct course of action or is there an easier way to flash almazny? Thank you for your help.

May I know, was Almazny working before, or arrived not working? Or did you migrate from ARTIQ-7 to ARTIQ-8 and Almazny stopped working?
There is legacy API that you may still use, by setting "almazny_hw_rev": "v1.1", without need of flashing the Mirny. I personally would discourage flashing it by yourself, unless you have L-type JTAG connector, because it typically requires disassembly of the boards sandwich, which is a bit tricky and involves risk of losing warranty.

As for the flashing, there is no real need in setting all the flakes. You just need an xc3prog and ISE installed with your favorite method: https://git.m-labs.hk/sinara-hw/assembly/src/branch/master/src/hw/mirny_almazny.md#flashing . The firmware is available at https://nixbld.m-labs.hk/job/artiq/gluelogic/mirny-cpld-almazny .

Hi,

Almazny was never working.

I was actually just running into that problem where the Almazny mezzanine was obstructing the connection to a standard JTAG adapter. I will try with the legacy API and hold off on flashing for now. I will keep you updated. Thank you for your help.

Hi again,

I am working with the legacy API of the Almazny "almazny_hw_rev": "v1.1" and have run into the error pictured below, when debugging with the artiq_sinara_tester. How and where do I define us? I am running ARTIQ 7.0.

Thank you.

kvziegler Hi,

I looked at coredevice.almazny.py and while the above error seems to have been resolved by https://github.com/m-labs/artiq/pull/2424, there was an additional missing import that I have submitted a PR for here https://github.com/m-labs/artiq/pull/2574. It should also be patched in for release-8.
