ESP32-8048S043C not programming and not stable usb connection

[eagl1]

Hi,

I have both ESP32-3248S035C & ESP32-8048S043C.

I was able to program ESP32-3248S035C easily on your web installer, but ESP32-8048S043C isn't programming.

But the ESP32-8048S043C is actually not stable in the usb connection, after a minute, it disappears from the usb connection when I try to program it, but it's display in the COM port list in the windows device manager.

It doesn't program on any platform, arduino ide, your web installer, openHAS web installer. I don't know why.

In arduino ide I get this error:

Sketch uses 248501 bytes (18%) of program storage space. Maximum is 1310720 bytes.
Global variables use 18456 bytes (5%) of dynamic memory, leaving 309224 bytes for local variables. Maximum is 327680 bytes.

Note: This error originates from pySerial. It is likely not a problem with esptool, but with the hardware connection or drivers.

This screen's CI build has some issues that i've yet to figure out (see #67)

For now, please try manually installing via platformio: https://github.com/suchmememanyskill/CYD-Klipper/blob/master/Manual_Install.md

I tried that:

The board is working and running the demo code came from the manufacturer but I can't program it.

[suchmememanyskill]

This is however, not what i asked you to do. I asked you to install via platformio, not via esptool...

Scroll down in the doc that i sent

(Btw, i suspect you're missing a serial driver somewhere)

[eagl1]

I installed platformio and opened the project folder.

I didn't get the menu like the one you posted in the tutorial.

[suchmememanyskill]

Again, please see the instructions.

You didn't click the bug/alien icon on the left side. This is (1) in the screenshot at the bottom of the instructions

[eagl1]

When I do this:

I get this:

And it asks me this in the output window:

UserSideException: Please install Git client from https://git-scm.com/downloads

Even I've already installed git

[eagl1]

And even when I again click on the alien/bug I get this project tree:

[eagl1]

OK, wait a minute ! I think I found the source of the problem.

The problem is that I installed VS code in another location other than the default one.

So I uninstalled and re-installed it as is, and I think it's working now and it automatically started the unpack your project :)

[suchmememanyskill]

So can you open the folder for your screen and select upload & monitor?

[eagl1]

Yep, but the same port problem:

The board is booting every time with the manufacturer lvgl demo, I couldn't program the board with anything else until now.

[suchmememanyskill]

Actually, weird question. Are you holding down the BOOT button while the screen is flashing on and off (so while it says connecting....) in the terminal?

This is stated both on my install page and in my docs, just want to make sure

[eagl1]

I did both methods with and without pressing on the boot button.

It detects the board but can't program it.

PermissionError(13, 'Access is denied.', None, 5) might be worth looking into. This error message usually means, at least from my side, that the device is in use. Meaning you have the screen connected elsewhere, possibly?

Either way, this does not seem to be a specific issue with my project, but rather a misconfiguration on your end

[eagl1]

Oh yeah absolutely, it's not an issue in your project. I tried to program it on different platforms, your method, arduino ide and the flash tool. No one worked.

I don't know what could be the problem, could it that there's no communication between the esp32 and the serial chip.

[eagl1]

And also thank you for your help even with platformio, that I couldn't get it to work until today, now I can program my board through vs code and platformio. That would be much faster than arduino ide.

[eagl1]

Who is the manufacturer of this display ?

The 4.3" I have isn't accessible in anyway, I tried to catch it with linux ubuntu in virtual machine but the same result.

I want to communicate with the manufacturing company and check what things I can do to resolve the usb connection issue.

[eagl1]

OK, it worked :)

I installed an old CH340 driver following this post: https://github.com/espressif/esptool/issues/682

More to mention, I couldn't program it with the web-installer. But with your platformio project.
