Please add the compiler-flag option to enable/disable the Serial TX/RX LEDs also for the XIAO SAMD21 board, like you already did for the Seeed Wio Terminal by accepting commit c68cc757e623a4b30669e7880a4fb0224bbf6169
Add to boards.txt:
seeed_XIAO_m0.menu.txrxled.on=On
seeed_XIAO_m0.menu.txrxled.off=Off
seeed_XIAO_m0.menu.txrxled.on.build.flags.txrxled=-DTXRXLED_ENABLE
Also, assigning the pin-numbers to PIN_LED2/3 (instead of PINLEDRXL/TXL) allows the user to reference the individual LED-pins, while still being able to enable/disable the LEDs with the compiler flag.
Please also correct the copy-paste typo in boards.txt for the Wio Lite MG126
from
# Seeed XIAO M0 (SAMD21)
to
# Wio Lite MG126 (SAMD21)
