Malformed packet when using gdb

[kolban]

I have a situation where my ESP32 hosted app fails. I changed my make menuconfig to halt and launch the gdb stub. When the app fails, my goal is not to launch gdb and see what happened. I run the following command:

Code: Select all

xtensa-esp32-elf-gdb ./build/app-template.elf -b 115200 -ex 'target remote /dev/ttyUSB0'

This returns the following:

Code: Select all

(gdb) 

What I'm curious about are the last few lines which read:

Code: Select all

Ignoring packet error, continuing...
Malformed packet(a) (missing colon): eout
Packet: 'T1feout'

Is this indicative of an issue or problem?
