Using esptool.py to install circuitpython on lilygo_ttgo_t8_

by fmentiplay on Mon Mar 15, 2021 6:03 am

Hello All
I am using esptool to install Circuitpython on the lilygo_ttgo_t8_s2_st7789.
The esptool executes without error (see below) but when I putty in I see code (ESP-ROM info etc) repeatedly flashing on the screen
Basically it seems that the install has not worked!!
Can any one offer some help to solve this problem.
Much Appreciated
