ULP example code does not build for ESP32-S3 under PlatformIO

Which example have you tried? Both (FSM and risc-v) ULP code does compile fine in my tests on the S3.

Oh just noticed, there are the old examples in the repo. In my fork I have updated to the recent ones from espressif.
So yes there is action necessary

Do you have copied the whole example folder with everything in there?
You have nothing to configure in menuconfig. All needed settings are in sdkconfig.defaults.esp32s3. Only set the S3 as env you want to compile. Hit compile button. That's all.

Do not make a new project. Use open folder from VSC to select the example project.
You don't need anything from espressif IDF. Everything needed will be installed and used from Platformio.

Mhh, do you have a config which uses different drives?
One part is done on [3/13] Generating D:/a/platform-espressif32/platform-espressif32/examples/espidf-ulp-riscv/ulp/main.c
All other is on drive c:/Users/runneradmin/
This one makes me believe something weird with your path(s) is going on
CMakeFiles/ulp_main.dir/C_/Users/runneradmin/

Do you have whitespaces or special chars in a path?
Do you use a network or cloud drive?

Whitespaces and special chars WILL make issues.
Cloud drives can make troubles.

Hi @peteDDD, if I'm not mistaken, the ulp_main.h file is autogenerated and should be located somewhere in your build directory, e.g. .pio\build\YOUR_ENV\esp-idf\main\ulp_main. Anyway, after all previous steps you tried, what error message do you see?

Valeros. My understanding is the same... ulp_main.h should be autogenerated and located in the build directory. But it is nowhere to be found on my computer.

The error is simply "cannot open source file for that the #include statements for "esp32s2/ulp.h" and for "ulp_main.h"
(pretty standard sort of error that I know how to fix... when the files actually exist and can be found)

Hi Jason,

Since the default (platformio) folder structure is used this part is not needed at all

# 2. Specify all assembly source files.
#    Files should be placed into a separate directory (in this case, ulp/),
#    which should not be added to COMPONENT_SRCS.

Just try and comment the line. Compile will be successful

Thanks, could you please also run your project in verbose mode and attach logs here? Just open the terminal window in the IDE and run the following commands one by one:

# Clean the project before build
pio run -t clean

# Run in verbose mode
pio run -v -j1

While that build is working (takes a really long time in verbose mode), I am wondering... the ulp_main.h, doesn't that just need to have in it the mapping of the ulp and main processor variables and if so, couldn't I just write that and put it in src? Somsthing like:
extern uint32_t ulp_edge_count;

BUT... on next run to upload... failed the same way.

So, I ran the clean and run again (without verbose logging) and was back to the same failure.

SO... repeated clean and verbose build... and it builds.

Now I guess I need to do a verbose upload.

peteDDD commented Jul 11, 2023

Verbose upload compiled and uploaded.
When funning, the monitor shows the processor going to ULP deep sleep but nothing happens after that.
No number of IO0 button presses trigger a wakeup and report.
Tried on two different ESP32S3 boards.
Checked in menuconfig that the ULP was enabled and set to FSM with 1024 bytes of RTC slow memory reserved.

great progress.... but still not quite there. Thank you!
I eager for more ideas.

One note. The building seems to be pretty non-repeatable. I have to go back and do a clean and a verbose build each time. Any other approach, such as just doing a verbose upload, does fails. Perhaps Platformio is going out and downloading more "meta" files that we have to clear out.

@valeros For me it does only compile when the main source code is in folder main. Your example setup does fail to compile. This one works for me.
espidf-ulp-pulse-test.zip

Edit with platform = espressif32 @ ^6.3.2 it fails now too. With Github Actions it compiles successful with IDF 5.0.2 ?!
Edit2: The example does fail with plain IDF 5.0.2. So it is not a Platformio bug
Same error

@peteDDD If possible, I'd like to look into a dependency tree generated on your machine. Please open the terminal in the IDE and follow these steps:

# Clean the project before build
pio run -t clean

# Set some special SCons flags
set SCONSFLAGS=--tree=prune

# Run the project and redirect the output to a file
pio run > esp32s3ulp-deptree-prune.txt

# Clean variable
set SCONSFLAGS=

Please share here the esp32s3ulp-deptree-prune.txt file.

Well life got a little out of hand for a while there, but I am finally back to this.

Summary of where I am now...
1: Today I downloaded espidf-ulp-pulse-test.zip which Jason2866 posted here on 11 July. The only change I made was to add monitor_speed = 115200 to the platformio.ini
2: This compiles and loads.
3: I have tried to run this on two different ESP32S3 boards. One is the genuine Espressif ESP32-S3-DevKitC-1U and one is an aliexpress knock-off with a wider footprint and more flash.
4: On the Expressif card, I get the following on the monitor... and then nothing else, no matter how many times I press the pin0 boot botton.
[CODE]
ESP-ROM:esp32s3-20210327
Build:Mar 27 2021
rst:0x1 (POWERON),boot:0x8 (SPI_FAST_FLASH_BOOT)

Not ULP wakeup, initializing ULP
Entering deep sleep
[/CODE]

On the knockoff ESP32-S3, I get the following:

[CODE]

5: @valeros you asked for the esp32s3ulp-deptree-prune.txt, It is attached.

While running the pio run to generate the deptree, it completed, but I got the following messages (my entries included here also for completeness):
[CODE]
PS C:\Users\peted\Downloads\espidf-ulp-pulse-test\espidf-ulp-pulse-test> pio run -t clean

fatal: not a git repository (or any of the parent directories): .git
[/CODE]

6: I also reconfigured my platformio.ini and uploaded the project to an ESP32 card (TTGO T-Display) and got similar behavior in that I got nothing beyond the "Entering deep sleep" message.

Thanks again for all the help and patience. Any ideas on why none of these processors is exiting the deep sleep?
