I’ve been using LilyGo TTGO T3_V1.6 boards in a project.
I haven’t been facing troubles for flashing the codes to the old boards I’ve got. They use Silicon Labs CP2104 USB to UART modem.
Now I’ve just took out of the box a new TTGO T3 board, labeled T3_V1.6.1, with FA1341 USB modem.
With the serial monitor I’m able to read what its native program outputs, but I can’t upload any code. The messages I get end with:
Serial port /dev/cu.usbmodemFA1341 Connecting.... Chip is ESP32-PICO-D4 (revision 1) Features: WiFi, BT, Dual Core, 240MHz, Embedded Flash, VRef calibration in efuse, Coding Scheme None Crystal is 40MHz MAC: xx:xx:xx:xx:xx:xx Uploading stub... A fatal error occurred: Failed to write to target RAM (result was 01070000) *** [upload] Error 2
I guess there might be missing a driver. Has someone any idea?
