OpenOCD + gdb Probleme

[Alexander M. (a_lexander)]

Hallo Zusammen,

Hier ist doch bestimmt ein "Debug"-Experte dabei, der mir helfen kann 
;)…

Es geht um das Debuggen des ESP32 Wroom mit OpenOCD, in VSCode (oder 
vielleicht zuerst auf der CMD...)

Command für OpenOCD:

 openocd -f interface/ftdi/c232hm.cfg -f board/esp-wroom-32.cfg

Zusätzlich in board/esp-wroom-32.cfg zugefügt, ansonsten gibt er mir 
einen Fehler:

Adapter_khz 1000

Aktuelle Ausgabe:

Info : Configured 2 cores
adapter speed: 1000 kHz
Info : Listening on port 6666 for tcl connections
Info : Listening on port 4444 for telnet connections
Error: type 'esp32' is missing virt2phys
Info : clock speed 1000 kHz
Info : JTAG tap: esp32.cpu0 tap/device found: 0x120034e5 (mfg: 0x272 (Tensilica), part: 0x2003, ver: 0x1)
Info : JTAG tap: esp32.cpu1 tap/device found: 0x120034e5 (mfg: 0x272 (Tensilica), part: 0x2003, ver: 0x1)
Info : esp32: Debug controller 0 was reset.
Info : esp32: Core 0 was reset.
Info : esp32: Debug controller 1 was reset.
Info : esp32: Core 1 was reset.
Info : Listening on port 3333 for gdb Connections

Das sieht meiner Meinung nach schon mal gut aus... ;)

Nun fehlt aber noch der gdb:
Command:

C:\Users\alex\Desktop\blink>xtensa-esp32-elf-gdb -x gdbinit ./build/blink.elf

gdbinit:

"target remote :3333", // Connect to OpenOCD
"mon reset halt", // Reset the chip and keep the CPUs halted
"set remote hardware-watchpoint-limit 2", // Restrict GDB to using two hardware watchpoints supported by ESP32
"flushregs", // Force GDB to get new state from the target
"thb app_main", // Insert a temporary hardware breakpoint at the main function
"c" // Resume the program. It will then stop at breakpoint inserted at app_main

und die Ausgabe ist Folgende...

Type "show configuration" for configuration details.
For bug reporting instructions, please see:
<http://www.gnu.org/software/gdb/bugs/>.
Find the GDB manual and other documentation resources online at:
<http://www.gnu.org/software/gdb/documentation/>.
For help, type "help".
Type "apropos word" to search for commands related to "word"...
Reading symbols from ./build/blink.elf...done.
gdbinit:1: Error in sourced command file:
Undefined command: "".  Try "help".
(gdb)

Vielen Dank für eure Hilfe, mit einer Lösung könnte ich glücklich ins 
Wochenende starten ;)...

Meines Wissens nach beinhalten gdbinit files keine "

/edit
Und auch keine Beistriche?

Sowie keine abschließenden Kommas und keine C++-Kommentare.

Kommentare fangen mit # an.

[Alexander M. (a_lexander)]

Vielen Dank! Oh man... ;)
Ja er tut "etwas", so richtig debuggen kann ich allerdings noch nicht...
Vielleicht will mir da auch noch jemand auf die Sprünge helfen, 
ansonsten werde ich da wohl weitersuchen müssen...

Ausgabe GDB, hier bleib ich allerdings auch "stecken" und kann keine 
Eingabe mehr machen..

Okay ich bin irgendwie doch schon in einem Modus, ob ich den aktuell 
schon als "Debug" bezeichnen würde, eher nicht.. :D

Für alle Interessierten, so siehts aktuell aus ;)

Debug-Symbole?

[Alexander M. (a_lexander)]

So im Groben funktioniert das jetzt, die Debug-Symbole werde ich mir die 
nächsten Tage anschauen ;)

Für die Interessierten:

- Ich habe die ESP-IDF Command Prompt verwendet 
(esp-idf-tools-setup-2.2.exe)
- der OpenOCD / der xtensa-esp32-elf-gdb müssen im Projekt aufgerufen 
werden
- der JTAG Adapter war der C232HM, Wichtig: mit dem Tool Zadig wurde der 
Treiber auf einen FTDI gewechselt --> somit war er lauffähig für den 
OpenOCD

Danke :)
