Help needed: TTGO TM 2.4" TFT not flashing new firmware
Posted: Mon Jan 28, 2019 7:41 pm
Hi
I just received a LilyGo TTGO TM 2.4" TFT board with webradio firmware already flashed.
I am trying to flash a new firmware with new WiFi parameters, but, I can't do it using IDF or flasher tool from Espressif.
The board just timed out waiting for packet header. I did try several baud rates, from 115200 to 961000 bps.
My IDF is under Linux and the flasher tool is under Windows 7. Both presents the same behaviour: "timed out waiting for packet header".
Perhaps this board is defective or it needs some special kind of procedure to flash new firmware?
I can connect a console with this board using make monitor or Putty at 115200 bps. All messages are printed normally.
Any help will welcome.
