Cannot access web interface on New Tesla LDU V6 Board

[Corndoglover999]

Hi, Been trying to fix this for days now and simply cannot figure this out. I am trying to program a new V6 board with the ESP32 Wi-Fi chip. I downloaded jsphuebner's esp32-web-interface from the github repository and followed instructions to flash via platformIO. Code builds & Uploads properly to the ESP32 Module through my serial adapter. However, when I power the board with 12v supply the ESP32 Module turns on and shows a network that I can connect to. I connect to it and try to access the web interface via https://192.168.4.1 and it simply won't open up the web interface. Only the power LED is displaying on board and the health LED is not flashing. I am pretty sure I am just missing something obvious here but for some reason cannot figure it out. Any help would be much appreciated, Thx.

Not https
Have you programmed the stm32 as well?

[Corndoglover999]

I have not programmed the stm32.

[Corndoglover999]

Is there a guide on how to program stm32 & esp32 on the V6 Tesla LDU Board?

I see some issues with the current state of esp32-web-interface. The version on my github is for CAN communication only, i.e. it won't work on a board. The version that does work was on Pete8008s github but he's deleted it. What a mess. Will try to fix this now.

Alright, now I have added the UART backend to my github as well: https://github.com/jsphuebner/esp32-web-interface

Read the readme file for programming instructions.

Hi !
I have been trying for several hours to get a new ESP32 WROOM32 operational with the web interface, but cannot get it to work.

After boot, it shows this in de serial monitor:

Right out of the box there was an Wifi-AP visible (unique ID, partial MAC?), after download nothing appears on the Wifi. Tried another ESP32 as well, same behaviour. Sketch used is the one referred to in de previous post of Johannes.

Further checked: Supply voltage is 3,32V and stable, pin3 (EN) goes delayed to '1' at boot (also tried some manual resets by shorting EN to GND).

Expecting to make some stupid mistake or forgetting something...

[johu]

Have you only programmed the file system but not the firmware? (pio run - - target upload)

[FJ3422]

Earlier I did the programming with Arduino IDE 1.x. (FS / sketch). Just installed the python / platformio environment and got the "pio run --target upload" and "pio run --target uploadfs" to work. Both successfully download serial to the ESP32 (after editing the platformio-local-override.ini) but unfortunately the behaviour of the ESP32 is identical. No wifi and the serial monitor shows identical.

EDIT: Just tried uploading a random ESP32-webserver example project, that runs ! Console outputs, wifi comes available and webserver functions. Can it be that there is some file missing in the https://github.com/jsphuebner/esp32-web-interface project ?

[FJ3422]

Did anyone else get the current version https://github.com/jsphuebner/esp32-web-interface running on an ESP32 (WROOM32 / Espressif) ? Tried two more random applications and they all download & run, just this one does not boot after download.

[uhi22]

I'm not using the latest (because I'm too lazy , but an older one. This shows after pressing and releasing the EN (aka Reset) button:

Couldn't start SD_MMC
Driver installed

and it works fine afterwards.

Just to sort things out: On https://github.com/jsphuebner/esp32-web-interface there are two branches: The uart-backend and the can-backend. I can only speak for the CAN variant. Depending which hardware environment you have, you need to get the right variant from github.
If nothing helps, you could add some additional debug prints in the setup() function, starting after DBG_OUTPUT_PORT.begin(115200), like DBG_OUTPUT_PORT.println("Here is the start of the setup"), to see how far it comes.

[FJ3422]

Thanks for the tips !

Just tried:
CAN-backend version
Initially stalled at the " (SD_MMC.begin())" instruction. After removing the SD initialisation, project runs & webserver is functional !

uart-backend version (which I need)
Does hang after the "entry 0x400805f0". Debug-message at the very first beginning of void setup(void) is nog even shown.
What does the ESP32 do before the setup call ?


[edit] The 'uart-backend version' had Serial2 defined as debug output port, so did not see anything on the serial monitor at the programming port. Set it to 'Serial' to find that the SD initialisation was also the issue here. Removed it and it works ! Thanks for your help !
