Hi,
I jump into this post to find some help.
This is my situation:
- Arduino Uno
- VS Code + Platformio
- Ubuntu OS
- I followed the instruction to use dwire-debug and I can connect to my Arduino via dwire and command line.
- I’m also able to program Arduino Uno using dwire-debug
but I have some troubles with the debug.
When I execute gdbserver in dwire-debug I get this output:
/opt/dwire-debug-master$ ./dwdebug device ttyUSB0, gdbserver, qr
Connected to ATmega328P on /dev/ttyUSB0 at 124899 baud.
Target ready, waiting for GDB connection.
Info : avrchip: hardware has something
Use 'target remote :4444'
What does it mean Info :
avrchip: hardware has something
However I can start a debug session from Platformio.
This is my Platformio.ini
[env:ATmega328P_dwire_gdb]
platform = atmelavr
board = ATmega328P
framework = arduino
board_build.f_cpu = 8000000L
; Debug
debug_tool = custom
debug_port = :4444
debug_server = /home/user/.platformio/packages/toolchain-atmelavr/bin/avr-gdb
debug_init_cmds =
set remoteaddresssize 32
set remote hardware-watchpoint-limit 1
target remote $DEBUG_PORT
In this scenario, I can place a break point but when I try to step to the next instruction, the program behaves as I execute a Run and also I cannot step inside a function.
Basically I cannot perform a step-by-step debug.
Is there a limitation of dwire-debug or something that doesn’t work on my system?
Because with Microchip Studio (on Windows) I can perform step-by-step debugging through dwire interface.
The other question is to program the target before start the debugging.
To do that, I added this line to my Platformio.ini
; Debug
debug_tool = custom
debug_port = :4444
debug_server = /home/user/.platformio/packages/toolchain-atmelavr/bin/avr-gdb
debug_init_cmds =
file "$PROG_PATH"
load
set remoteaddresssize 32
set remote hardware-watchpoint-limit 1
target remote $DEBUG_PORT
but when I start the debug I get this error:
Reading symbols from /home/user/Documents/Test_Projects/Arduino_Blink/.pio/build/ATmega328P_dwire_gdb/firmware.elf…
done.

Is there something can I do to solve these problems?
Thank you!
