I'm trying to flash the device to change the log2_width setting and am running into a timeout error [WinError 10060]. I've already successfully generated the binaries through AFWS, produced the boot.bin file, and am now attempting to run artiq_coremgmt -D 192.168.1.75 config write -f boot [afws_directory]/boot.bin. I have confirmed that this is the correct IP address specified in device_db.py, and I am able to ping the device. The error I receive is as follows:

artiq_coremgmt -D 192.168.1.175 config write -f boot C:\Users\esvd\Documents\BB_ARTIQ\artiq-bb-afws\boot.bin

I saw some discussion of this error here but am not sure whether I am facing the same issue, as I attempted to power cycle the device with a long down time (~ 30 minutes) and the error persisted. The device was purchased before September 2022 (the date of the post linked above) so it is possible that the fan issue may be relevant. The ethernet connection as indicated by the LED on the chassis is established, and I have the acqtl_moninj_proxy running. Please let me know if there is a solution to this issue, and if you need more information from my end I am happy to provide it.

    Which one is the correct IP address? You have .75 in one command and .175 in the other.

      Apologies, the correct IP ended with .75, and that typo was exactly the issue, I didn't catch that when checking whether the IP address matched. This was a frivolous mistake and probably did not warrant a post on the forum.
