[BUG] FlashNextion outputs fine but nothing happens? about nspanel-issue-graveyard

[joBr99]

@hirparak this isn't the same problem, I cannot see any response from the panel in your log, try to reseat the display connector

[joBr99]

in case it's a timing issue; this might help

joBr99/nspanel-lovelace-ui@e4a4917

would be nice if you can

1. re-enable weblog 2 which is the default
2. try to reproduce the broken flashnextion
3. delete autoexec.bec and replace the content of autoexec.be with the lastest content from here:
   https://raw.githubusercontent.com/joBr99/nspanel-lovelace-ui/main/tasmota/autoexec.be
4. reboot
5. retry flashnextion

[joBr99]

nope, I think the difference is that you've now the lovelace firmware installed (which is sending periodic messages and the stock one isn't)

my guess is that this 80808080 are messages from the panel in 115200 baud, interpreted by the berry driver that already switched to faster baud rate for flashing

[joBr99]

okay let's hope that this finally solves the flashing issues with the new tasmota version :)

My guess was/is that the serial commands are sent to fast to the nextion screen with the new tasmota version (due to updated serial lib's and platform core).
With weblog 3 tasmota has more to do (sending stuff to the weblog websocket), which theoretically also delays sending thoose serial messages.

[alexisml]

Thanks for your help and hard work with this project!

[joBr99]

type weblog 3 in the console and add the more verbose log to this issue, restart tasmota before your next attempt

you can upload/redo the firmware upgrade in the secureboot interface a second time, that should work

[alexisml]

Steps I performed:

1. weblog 3
2. Restart
3. FlashNextion http://nspanel.pky.eu/lui-us-p-release.tft

It now is somehow working...? What? (with a million logs as expected)

I have a second NSPanel with the same behavior, do you want me to try something different in that?

[joBr99]

hmm, I guess the restart did the trick in this case

[alexisml]

Believe me, I restarted it a ton of times, even power cycled.
Second NSPanel steps:

1. Restart
2. FlashNextion http://nspanel.pky.eu/lui-us-p-release.tft
3. -- wait 1 minute --
4. Nothing
5. Restart
6. FlashNextion http://nspanel.pky.eu/lui-us-p-release.tft
7. -- wait 1 minute again --
8. Nothing, again

[joBr99]

please check what the output with weblog 3 is on the second panel

would be also interesting to see if FlashNextionAdv3 http://nspanel.pky.eu/lui-us-p-release.tft works, as this doesn't change the serial speed (but slower due to that)

[hirparak]

I've had the same issue. The restart didn't help

[alexisml]

please check what the output with weblog 3 is on the second panel

would be also interesting to see if FlashNextionAdv3 http://nspanel.pky.eu/lui-us-p-release.tft works, as this doesn't change the serial speed (but slower due to that)

Tried the second one before changing the log level (FlashNextionAdv3 http://nspanel.pky.eu/lui-us-p-release.tft). Nothing happens.

What output do you want me to look for? After triggering the flash?

[hirparak]

I've reseated a few times, and no change. I guess I have somehow killed the display connector. I'll try on the backup one 😔

[joBr99]

@hirparak you can try tasmota 12.2.0 and it's also possible to send some nextion commands to check if the panel is doing anything; however it looks like your panel isn't responding

[joBr99]

@alexisml if the flashing doesn't start there won't be much more log than with the default log verbosity, just want to see the respose from the panel

[alexisml]

Ok, steps:

1. Restart
2. weblog 3
3. FlashNextion http://nspanel.pky.eu/lui-us-p-release.tft

...and nothing happens. Not sure what is going on tbh

[joBr99]

so, you are getting a respose from the panel
16:37:55.058 NXP: Received Raw = bytes('636F6D6F6B20322C33303631342D302C4E5834383332463033355F303131432C...')
-> comok 2,30614-0,NX4832F035_011C,

however the flash init command apparently doesn't do anything - no clue why

try a restart and then FlashNextionAdv3 http://nspanel.pky.eu/lui-us-p-release.tft in case it doesn't work downgrade to tasmota 12.2

[alexisml]

Restarted and triggered, this time it worked. Somehow having the logs in 3 helps (but only after a restart).

To sum up:

1. Restart
2. weblog 3
3. FlashNextion http://nspanel.pky.eu/lui-us-p-release.tft
4. -- doesn't work --
5. Restart
6. -- we are still at weblog 3 --
7. FlashNextion http://nspanel.pky.eu/lui-us-p-release.tft
8. -- works --

[joBr99]

no, clue weblog is a command from tasmota and I've never had such issues until the latest tasmota release, so the only thing I could imagine that it is timeing related and to fast with the new tasmota version ... really no idea

it works toally fine on all of my panels with the newest tasmota version, I will try to add some busy waiting before the flash init command to the panel

[alexisml]

1. Restart (I was already at weblog 2)

[joBr99]

with the unchanged berry driver?

[alexisml]

Yup, I didn't change anything else (other than logs set to 2). I had it working since #28

[joBr99]

okay so it's at least reproducible for you, can you retry with the updated version of the berry driver?

[alexisml]

But isn't this another bug? I was not getting this error before, I was just not getting anything. I can try though.

[alexisml]

1. delete autoexec.bec
2. delete autoexec.be
