CONFIG_GDBSTUB_BUF_SZ

GDB backend send/receive buffer size (in bytes)

Type: int

Help

This specifies the size (in bytes) of the send/receive buffer
for GDB backend. This needs to be big enough to hold one
full GDB packet at a time.

Direct dependencies

(GDBSTUB && SOC_ESP32) || GDBSTUB

(Includes any dependencies from ifs and menus.)

Defaults

840 if GDBSTUB
256
