ESP32-Pico-V3 fails to upload/debug using esp-prog

lienbacher · October 26, 2020, 9:22am

I am trying to use esp-prog on a custom board using an ESP32-Pico-V3 SoC. Uploading fails with the following error:

According to sprite from Espressif this indicates an outdated openocd version: “You possibly need to update your OpenOCD packages… the V3 ESP32 silicon has some small changes to the way JTAG works, and your OpenOCD doesn’t seem to take that into account.”

I have tried manually updating the openocd version that comes with platformio, but that did not work at all.
Any ideas/suggestions?
thanks!

We really, really need a “solving ESP32 debugging problems” post. The steps to debugging this are scattered over at least 20 posts in this forum and most problems can be solved by this…

manuelbl · October 26, 2020, 9:44am

@valeros @ivankravets There is a surge of problems related to ESP32 debugging – likely due to the new ESP32 chip variants released by Espressif requiring a newer OpenOCD version. Any plans to update it to the latest version?

maxgerhardt · October 26, 2020, 9:53am

Try the following troubleshooting steps in Cannot debug esp32 - #10 by maxgerhardt (that is, lower adapter speed, recheck all JTAG wiring, update tool-openocd-esp32 manually, use a different board_debug.openocd_board file in the platformio.ini, check flash voltage (3.3V vs 1.8V)).

“update openocd” issue: Update openocd · Issue #413 · platformio/platform-espressif32 · GitHub

lienbacher · October 26, 2020, 10:04am

Well, the wiring is 100% correct, if I try basically the same board but a revision that was still using the Pico-D4 debugging works fine out of the box. Just with the V3 silicon it refuses. I have not found thread related to V3 issues, so I opened a new thread, especially with the note I received from Sprite I found it worth creating a thread.

I have tried lower clock speed with no change of the symptom. I’ve also tried just replacing openocd with the version from july and now I get this error:

It’s still running at 20MHz, I think you have to change this in that file

(That also helped for a PICO-D4 according to an issue)

Since this issue seems to be actually new and unrelated to all other posts that was indeed the right thing to do.

Now the question here is if even the latest released esp32 openocd version from July 2020 is too old. Since I don’t have a Mac, I’m unable to compile the most recent version, and I also can’t seem to find officially released packages which are newer (or I have overlooked them).

Now to test this either someone can build for Mac or I’m building it for Linux and the thing has to be tested in a Linux VM with the USB debugger passed-through.

lienbacher · October 26, 2020, 10:20am

Yes because I reverted the change after it made no difference already 2 days ago, thus it is not reflected in this message. I did try and the error message did reflect the changes in adapter speed.

I’ll try to get it compiled for mac.

lienbacher · October 26, 2020, 10:23am

Ah, I just checked, the latest commit is from jul 6th and the release from jul 9th, so there is no point in compiling

Is the reason the latest openocd version fails maybe still related to a config issue?

maxgerhardt · October 26, 2020, 10:49am

Latest commits are from 9 days ago:

lienbacher · October 26, 2020, 11:33am

Ah I see my mistake, i was on the releases page and expected the current master branch when I clicked on code.
Trying to compile but I am presented with a bunch of compile errors

lienbacher · October 26, 2020, 12:01pm

The folks at openocd say support for Eco3 silicon was added with v0.10.0-esp32-20191008.

They have also asked me to run OpenOCD with -d3 option to collect more verbose log. How would I be able to add this parameter using platformio?

lienbacher · October 26, 2020, 12:24pm

I’ve run openocd manually via terminal from the platformio install to supply the folks at github with the log, and to my personal surprise (I did not check the log toroughly and posted it anyway) it worked fine.

So it seems the issue is not openocd. Any ideas?

maxgerhardt · October 26, 2020, 12:28pm

Either see Redirecting... for using debug_tool = custom and debug_port = localhost:3333 etc for using a pre-opened openocd server, or modify this code locally on your machine

to say openocd_args = ["-d3"] (or any other debug level. This file should be in <home directory>/.platformio/platforms/esp32/builder/main.py.

Upload and stepping worked fine? Then there’s something with the timing. Running on -d3 adds a considerable amount of debug output and delay between individual executions of commands, which may influence things just in the right direction.

maxgerhardt · October 26, 2020, 12:30pm

Seems familiar to my when you don’t use the --disable-werror option in the ./configure <options> command. But since it works on pre-compiled released versions, just a side note.

lienbacher · October 26, 2020, 1:45pm

I only did an upload, assuming it would fail that’s why I posted the good log without checking

With your help I’ve managed to run openocd from within platformio with the d3 argument, and this is the output in the console: Uploading .pio/build/esp32dev/firmware.binOpen On-Chip Debugger v0.10.0-esp32 - Pastebin.com (too long to post, thus pastebin)

seems the problem has been identified: https://github.com/espressif/openocd-esp32/issues/125#issuecomment-716588856

Changing program_esp32 to program_esp in main.py at L374 and L380 fixes the issue with uploading.

                  "Please specify `upload_protocol = espota` in `platformio.ini` "
                  "project configuration file.\n")
          
          
if upload_protocol == "espota":
              if not env.subst("$UPLOAD_PORT"):
                  sys.stderr.write(
                      "Error: Please specify IP address or host name of ESP device "
                      "using `upload_port` for build environment or use "
                      "global `--upload-port` option.\n"
                      "See https://docs.platformio.org/page/platforms/"
                      "espressif32.html#over-the-air-ota-update\n")
              env.Replace(
                  UPLOADER=join(
                      platform.get_package_dir("framework-arduinoespressif32") or "",
                      "tools", "espota.py"),
                  UPLOADERFLAGS=["--debug", "--progress", "-i", "$UPLOAD_PORT"],
                  UPLOADCMD='"$PYTHONEXE" "$UPLOADER" $UPLOADERFLAGS -f $SOURCE'
              )

It did not fix debugging though, I guess it is a similar if not the same issue though. Any pointers would be very appreciated!
Thank you for your fast help!

It looks as if the command:

flash flash write_image erase .pio/build/esp32dev/firmware.bin 0x10000 verify

was used instead of:

flash write_image erase .pio/build/esp32dev/firmware.bin 0x10000 verify

And then the command file parsing fails (error -1404 is raised if OpenOCD cannot determine the image type based on the filename).

If so, the problem could be in PlatformIO or in one of the config files.

Well, if you read the issue on github and this thread it seems rather clear to me that the problem is with platformio.

If by any chance you find a quick fix I can apply to get debugging working I’d be incredibly thankful! Uploading works now, which was not a big issue because I could always upload via serial. Spent all day tracking this down to get debugging working. I am glad it’s not a hardware issue with my prototypes though!

manuelbl · October 26, 2020, 4:26pm

What have you changed? Why does uploading suddenly work?

ivankravets · October 26, 2020, 5:33pm

We’ve just updated openOCD to the latest version but you will need the latest PlatformIO Core Dev and special branch of ESP32 dev-platform. If this works for you, we merge it into develop branch when release PlatformIO Core 5.0.2.

How to try?

Please open PlatformIO Core CLI in VSCode (terminal icon on the blue bottom bar) and type:

pio upgrade --dev

Use this line in your platformio.ini:

[env:yourenv]
platform = https://github.com/platformio/platform-espressif32#feature/openocd-update

Does it work?
