11 months ago Compilation was a few hours ago, so probably v4.1.2
We have release v4.1.3 a couple of hours ago, so if you want update it, it might be a good idea. You dint have to go the whole process anymore, as you may be able to see the panel in your ESPHome dashboard, so just click the 3-dot menu, select "Clean build files", then click "Install" and select the option to install it wirelessly, so you dint have to disassemble your panel again.
I will come with some more comments to your message in a minute,

tl;dr
I'm pretty sure I've already followed all the troubleshooting steps as far as they apply, and I am trying to load nspanel_blank.tft first, but the display doesn't seem to be going into programming mode at all. I went all the way to hooking up a logic analyzer to see what the ESP and display are doing, but didn't really get anywhere.
Context
I'm almost completely new to HomeAssistent, and am completely new to ESPHome. Thus far I've just been making and programming my own microcontroller + relay boards. My only prior experience is from a few months ago, when I first tried to get my NSPanel to do something. I went for the Tasmota + lovelace UI TFT file, but ultimately tossed it in a corner for half a year because it wasn't doing what I wanted. I'm not sure this project is doing that either (I'm looking for something lightweight that I can use as baseline for my own C programming, in particular because I was hoping to use some spare I/Os on the NSPanel to connect to my homebrew serial network), but regardless, I figured I'd give it a try. I'm afraid I don't know exactly which commit at joBr99/nspanel-lovelace-ui I stuck on there, but I was working on this mid August so it'd be some commit around that time, and I do know I never got around to changing HMI files.
What I did
What went wrong
The Nextion never seems to enter its programming mode; it keeps showing the lovelace UI "no response from HomeAssistant yet" spinner. That spinner does start lagging a whole lot, its refresh rate reducing to the rate at which the ESP is spamming
[xx:xx:xx][W][nextion:077]: Nextion is not connected!. After letting it run for a few minutes, I decided it's probably not working, so I power cycled. The spinner comes right back up again, so if it did program anything, it couldn't have been much.What I already tried
From the troubleshooting page:
1) Using a local source. I already am. Also checked to make sure behavior is different when the file is not being served by HA. 2) HTTP instead of HTTPS. Seems N/A. 3) Network issues. I doubt this has anything to do with it, everything else on the network seems stable. 4) DNS. Seems N/A. 5) Check the file size by downloading to your computer. Way ahead of you, I already did an md5sum check just to be sure. 6) Power cycle your panel. I tried several times. 7) Flash your panel again. I didn't have any customizations to begin with; everything, including HA itself in fact, is a fresh install. Since the device showed up in ESPHome just fine, I'm not sure what flashing the same thing again would accomplish in my case. 8) Alternative http service. I didn't try this, because as part of step 1 I'm already pretty sure the download is not the problem.
I tried to look for similar issues, but there are so many of them that I quickly got lost. This part of the log (full log here) seems different from the issues I've seen:
To further debug, I tapped into the serial port between the ESP32 and the Nextion with my logic analyzer by soldering to the respective test points. Data attached; the .sal file can be viewed with Logic regardless of whether you have a Saleae device or not. I'm not sure what's going on with this link because I've yet to dive into the Nextion docs. I guess that's next on my todo list (that, or buying a new NSPanel...), but I figured I'd ask here, too.
Any ideas on where to go from here?
