[BUG]Incompatibility between esp32 latest core (2.0.6 / 2.0.7 => PIO 5.0~6.1) and TMC2209 in UART mode #65

Marlin 2.X
SDK issue
Using updated arduino core : 2.0.6/2.07 => PlatformIO 5.0~6.1
ESP3DLib is working well but Marlin UART TMC support has issue
if using TMC2209_STANDALONE for the drivers, it is Ok
but using TMC2209 in uart mode will go to dead loop at start
It is not directly linked to ESP3DLib because ESP3DLib does not use / affect stepper drivers but it is esp32 core itself compatibility issue.
Reproduced on several Marlin version 2.1.1, 2.1.2, latest bugfix
Because It is more an esp32 / Marlin / TMC compatibility issue and because my knowledge in Marlin /TMC is limited, I currently do not have solution right now
any feedback / solution to Marlin is welcome
