# The TDI pin of ESP32 is also a bootstrap pin that selects the voltage the SPI flash
|
|
# chip runs at. When a hard reset happens (e.g. because someone switches the board off
|
|
# and on) the ESP32 will use the current TDI value as the bootstrap value because the
|
|
# JTAG adapter overrides the pull-up or pull-down resistor that is supposed to do the
|
|
# bootstrapping. These lines basically set the idle value of the TDO line to a
|
|
# specified value, therefore reducing the chance of a bad bootup due to a bad flash
|
|
# voltage greatly.
