Problems updating - blank tft good, but rest not

[rploeg]

I tried to update yesterday my devices to 3.2.2 (blueprint, TFT and ESP yaml). I was stuck like some other people with the [11:54:05][W][nextion:396]: Nextion reported variable name invalid!'

So updated my device with the blank tft image, that was successful (but still including the above error). But then I tried to update the TFT eu version and still my blank tft was loaded. So it looks like my blank TFT is loaded, but nothing more is possible. I have tried to update flashing via cables (not wireless), but still the blank image is loaded (looks like). When I try do it wirelessly I see it's successful, but again the blank tft is loaded with the same error.

And again the blank TFT is loaded with the above variable invalid error.

Then I click on TFT update and get the error on my screen:

Model does not match

And see then this in my logs

`

So it looks like my blank TFT is loaded

If nspanel_blank.tft is loaded, you should be seen a totally white screen, with no text and no way to turn off other than disconnecting power supply.
Is that your case?

Could you please share the ESPHOME yaml you are using? Please remove any sensitive information (wifi settings, etc) before sharing.

[rploeg]

@edwardtfn Yes, that is the case (white screen). here is my esphome yaml - sorry for the weird formatting

If you go to Developer Tools > Services and then look for service ESPHome: nspanel01_upload_tft_url, add the url of nspanel_eu.tft and click "Call service", what happens? Any error message on Home Assistant? Anything happens in the device's screen? Anything on ESPHome logs?

[rploeg]

Then I get this error (in the logs of my panel):

`

`

and then see the 'Model does not match' on my screen.

I have tried the flashing with an USB setup with the right TFT and also wireless upgrade. Also tried another www server to host the TFT file, but get exactly the same issue.

[edwardtfn]

This is weird. I wouldn't expect this error when the TFT blank is already installed. It looks like your panel is in reparse mode, but that should be the case when nspanel_blank.tft is installed.

I would suggest installing the beta version temporarily, so will be able to try different baud rates, but let's start with this:

And please let me know what you see when you try to update TFT.

[rploeg]

@edwardtfn exactly the same issue - output on the display is 'Model does not match' And still the blank screen after rebooting

[edwardtfn]

output on the display is 'Model does not match'

This looks like a corrupt TFT fille.

Which one have you used? nspanel_blank.tft or nspanel_eu.tft?

[rploeg]

nspanel_eu.tft hosted on HA, but also 2 other machine. When I download the files from Github I see this:

It is correct that the eu.tft version is smaller then the blank one?

[edwardtfn]

It is correct that the eu.tft version is smaller then the blank one?

Nope!
nspanel_blank.tft looks right size, but nspanel_eu.tft should be around 7Mb.

[rploeg]

@edwardtfn yes I see it. when I do 'save as' of the TFT file from Github the file is smaller. If I indeed do a full git clone I see that the file is 6MB. I will try the new file. Do you advise to use the beta version?

[edwardtfn]

nspanel_eu.tft from main is 6.19Mb:

https://github.com/Blackymas/NSPanel_HA_Blueprint/raw/main/nspanel_eu.tft

[edwardtfn]

Do you advise to use the beta version?

No. Try the MAIN first. On beta we fixed a lot of bugs, but you might find unknown new bugs, so main is probably a better choice to start, then you go beta later if you want.

[edwardtfn]

When you have successfully uplodade TFT, you should have your ESPHome file looking like this:

I have the same issue. I followed the external_compents to update TFT and get the following. It seems this update removed all the variable mismatches initially on reboot. It runs up to 90% quickly and then hangs. Going to try the blank one with this ext comp setup

Uploading the file directly from GitHub increases a lot the chances for something in the network to fail, making the whole process too fragile, given the long time it takes.

I would highly suggest to host the TFT files locally and use that local url instead.
By the way, since you already have seen the TFT download screen once, that means you don't that old library (external component) anymore. You can safely remove that.
And.you don't have to compile EAPHome again, just go to Developer Tools > Services, look for the service ESPHome: nspanel01_upload_tft_url ad the url for the TFT you want to upload and click `Call service'. It should work.

[haywiremk]

I get the following when trying to do a remote pull of the blank tft. I generally do a local load of the TFT files but was trying remote to see if the local file had any issues.

I did a local download and was able to load this blank file. Once loaded switched back to the nspanel_us.tft and it loaded from 0% to done successfully. Maybe this is something to do with the CRC checking to skip the first 90% (had 3.2.0 previously) as the external_compents did not help until I flashed the blank file from a local HA file. Also do still see time outs when loading but they go away. Maybe just timing for UART setup. There seems to be a few posts on this nextion issue. As I mentioned in another before finding this one I have 3 units. 1 loaded tft just fine. Second timed out with Panel Mismatch and a power cycle and tft load second time fixed. Third went from 90->93 and hung for and hour then a power cycle showed System Data ERROR! A tft update afterwards would speed to 90% and then hang with the UART timed out error. This was the one I loaded the blank tft on and then could load the us tft file again successfully all using local files.

Below is log from the blank file load.

hi @rploeg how are you? how do you fix the "Nextion reported variable name invalid!" message?

[edwardtfn]

how do you fix the "Nextion reported variable name invalid!" message?

This message can be related to an incorrect TFT file installed or a know bug that is already fixed on dev. If you have your device working properly, don't worry about this message.

Yes, the device is working without issues :)
I already install the "https://github.com/Blackymas/NSPanel_HA_Blueprint/raw/dev/nspanel_eu.tft" but I'm getting the same message.

hi @rploeg how are you? how do you fix the "Nextion reported variable name invalid!" message?

my problem was that I used a 'save as' in GitHub on the EU TFT file (and did not downloaded the full repo). This became a smaller version of the original file. Downloading the whole repo and use the TFT file from their did the trick for me
