Hello,

I built my debugger more than a xear ago by milled PCB, so wire connection should be no problem, because everything worked well. No on my home PC, I m not sure but I believe I one time debugged ESP32 @ home, despit I can not debugg simple blink example.

All setup is done as described in the tutorials vmicro.

Output.txt is attached.

Many thanks in advance,
Christoph

Thanks for the report.

Can you update Visual Micro to the latest version available from the Download Page below, and see if this resolves the issue?

Thanks for the update, can you update the ESP32 board package to v2.0.3 or v2.0.4 as I believe this version has an issue with the GDB.exe packaged with it.

The board package update will resolve this side of things as well.

Thank you for now! Unfortunately there is again an error Sad

My cable for FT2232H mini modul is different but I used it for download pictures from my gopro.

Thanks for the update, can you attach the log file from the below location:
Code
Select All
ugOpenOCD.log


Can you also confirm the pins used in the sketch are not any of the JTAG pins (12,13,14,15)?

Hello again and sorry for the big delay!! I got stuck in some other arduino project.

Here is the desired file attached.

Unfortunately I can not attach files anymore Sad I will send via email and the link of this post.

About the blink code, I can confirm only using 
#define LED_BUILTIN 2

and the code with digitalWrite() and delay()

Thanks for the log and the confirmation.

If you are uploading the sketch via the programmer, I suspect it isn't actually running (opening the serial monitor will prove if this is the case, as it will be constantly outputting errors/resetting).

Can you upload the sketch using the USB-Serial connection directly to the ESP32, and then try attaching the debugger from Debug > Attach to Process?

From my current understanding there is something different or incorrect with the bootloader.bin images uploaded when using the programmer in the 2.0+ versions of the ESP32 Board Packages.  We are still investigating the fix for this.

If you add a local board.txt to your project (vMicro > Add Code > Local board.txt), and paste the below content, it won't upload the bootloader (just sketch, app, partitions), which should allow the upload via programmer to work correctly:
Code
Select All
tools.openocd.program.pattern="{program.path}/{program.cmd}" {program.verbose} -s "{program.path}/share/openocd/scripts/" -f "interface/{openocddebugger}" -f "board/{upload.openocdscript}" -c "echo -n {****[vMicro]**** Uploading App :}" -c "telnet_port disabled; program {{runtime.platform.path}/tools/partitions/boot_app0.bin} 0xe000"  -c "echo -n {****[vMicro]**** Uploading Sketch :}" -c "program {{build.path}/{build.project_name}.bin} 0x10000"  -c "echo -n {****[vMicro]**** Uploading Partitions :}" -c "program {{build.path}/{build.project_name}.partitions.bin} 0x8000 reset; shutdown"

Added board.txt solved the problem as you described and programming via debugger is now working liked the common way.

Thank you very much for your help  Smiley

Just to update on this, there was an issue in the 2.0.4 ESP32 Board Package which caused the bootloader issue.

If you update it to 2.0.5, and then comment out the board.txt entry (put a # at the start of the line), it should then work as expected after rebuilding and uploading.

Hi Simon,

I added the board.txt , comment out # , tried new board versions from v2.0.4 until v2.0.8 and extra seperate v2.0.16.
In updating board versions I always tried flashing new debugger blink scatch on a esp32 with different scatch running. With the [Enable programmer] feature via COM Port from the debugger F2232 mini module, it was never successfull.

Always getting error like in the attached Output-MicroBuild.txt . this was with the v2.0.16 board version.

I discovered, when [Enable Programmer] is not selected, and I select the COM Port for the ESP 32 USB to UART , everything is like expected and I can debug imidiatly and hitting the breakpoint.

I mean its fully okay, but I was familiar with the [Enable programmer] selected way of programming. Why is this new behaviour and is therfe any drawback ?

Many thanks in advance,
Christoph

The Enable Programmer, means the sketch is uploaded via the JTAG lines from the FT2232 probe, and does not use either the COM Port from the FT2232 or the USB COM Port to the board.

From the errors in the log it often means there is either a problem with wiring (which is doubtful if the upload and debug work without the programmer), or it could be a state or timing issue.

Do you have the same error if you disconnect both the board and probe, then re-plug them, and then try the upload via Programmer again (just using the vMicro > Uploader > Upload Last Build button)?

Setting was COM Port for USB to Uart, no [Enable Programmer]
Flashed a different skatch.
Disconnected both connections.
Rebuild Solution blink debugging skatch.
Did the vMicro > Uploader > Upload Last Build.

Worked but no debugging started , just successfully flashed.

Did the same again, just with [Enable Programmer] selected and COM for FT2232 and got the same error. Output attached
