Can't flash the LILYGO T-A7608E-H board

[matthieu-sofa]

Hi here,

I ordered some LILYGO T-A7608E-H boards for a side project but I'm not able to flash the firmware on them.

I'm receiving the following error via ArduinoIDE: `Sketch uses 296122 bytes (22%) of program storage space. Maximum is 1310720 bytes. Global variables use 14308 bytes (4%) of dynamic memory, leaving 313372 bytes for local variables.

A fatal error occurred: Failed to write to target RAM (result was 01070000) A fatal error occurred: Failed to write to target RAM (result was 01070000)`

Do you know if there is a specific procedure to have the board enter the flashing mode? I previously used the Lilygo SIM800L and never had issue.

Here are my settings: My board is connected via USB-C to my Mac

The file I'm trying is the one we can find on this repo: https://github.com/Xinyuan-LilyGO/T-A7608X/blob/main/examples/Arduino/HttpsClient/HttpsClient.ino

Thanks a lot for your help.
