Problem with boot mode on T-Deck about t-deck HOT 16 OPEN

Try this method!

Ok So I got a boot load problem and I did figure it out. The ESP32-S3 need to have GPIO0 and GPIO46 to 0 to go into the boot load mode but the ESP32-C3 int is connected to the GPIO46 and disturb the very high resistor pull down value.

So shorting the GPIO46 and the same time that I press the GPIO0 button , then press the reset and release both GPIO0 and GPIO46 does the trick. This tooks me 2 evenings to figure out why the T DecK didnt want to go to boot load. Im sure I`m not the only one with this problem.

THANK YOU THANK YOU, fixed my issue uploading code. removing D2.

I have the same issues. erase_flash works fine on T-HMI and on T-Display-S3 but the T-Desk either times out (non bootloader mode) or stalls (bootloader mode by pressing the trackball-button). I also tried it under Windows 11 and on MacOS.
I only once was able to install Micropython .. probably this bricked my T-Desk.

Unfortunately the linked instructions are the ones I've already followed and does not make bootloader mode work on the T-deck. I am still unable to flash when the T-Deck is in bootloader mode on any of my devices.

Please take a photo of the PCB on ESP32S3 and show it to me.

Hello, I tried all kinds of setting on the Windows Flasher, but I always see the same behaviour:
If not in bootloader-mode (on COM5): it just runs forever

test offset :  0 0x0
case ok
.................................................................................................................................................................................

if in bootload-mode (COM4 or COM7): it waits some seconds and returns with a message box saying:

2-sync fail: 
Tips: Please refer to the chip dataset and confirm that strapping pin's status is correct.

KInd regards

Here's my PCB:

Please try to remove D2

Thanks!

Removing D2 worked perfectly fine for me! Uploading new firmware is no longer a problem.

Kind regards

I just received two T-Decks with the D2 jumper. Should they be removed in all cases? Kindly explain before I have the same problem.

from t-deck.

Can confirm. i was having the same problem and removing D2 fixed it.

from t-deck.

Had the very same problem.
Removing D2 works to use simple commands like chip_id.
However, I had to upgrade to esptool.py v4.7-dev (direct from the github repo) to get erase_flash etc. working.

Wow, talk about fast fix to the production line: I just received two T-Decks ordered 2 weeks ago and notice D2 is not installed on either. I don't see any version info on the PCB though, is there any way to tell the difference?

Name of God thank you for this answer I've been looking for a solution for 3 days
