How to run menuconfig to update Kconfig for ESP32 ?

[GitHubLionel]

Hi,
I need to add some directives to my project (CONFIG_ADC_CONTINUOUS_ISR_IRAM_SAFE and CONFIG_GDMA_ISR_IRAM_SAFE).
It doesn't work if I add this directives with project/properties/Sloeber/"Compile options" with "append to C/C++" or Link.
I ask in Espressif forum and the answer is to use menuconfig.
How can do that with Sloeber ?
Best regards,
Lionel

project/properties/Sloeber/"Compile options" with "append to C/C++"

This should work. Can you provide what you have put there and the command from the console you and the command you want?

the answer is to use menuconfig.

If they are not talking about the menu options is project/properties/Sloeber I have no clue what they are talking about.

I add -DCONFIG_ADC_CONTINUOUS_ISR_IRAM_SAFE -DCONFIG_GDMA_ISR_IRAM_SAFE
and I can see this in the log:

So it is correct.

the answer is to use menuconfig.

If they are not talking about the menu options is project/properties/Sloeber I have no clue what they are talking about.

They are talking about the Kconfig file.

The problem is that my program continue to crash with this message:
Guru Meditation Error: Core 1 panic'ed (Cache disabled but cached memory region accessed).
This message indicate that ADC functions are not in IRAM.

EDIT : If I decompose the line in the log, you can see some mistakes on line 27 and 31: the quote " is in bad position.

But I don't think this is the origin of the problem.

[GitHubLionel]

NOTE2:
I also try with this directive: -DCONFIG_ADC_CONTINUOUS_ISR_IRAM_SAFE=1 -DCONFIG_GDMA_ISR_IRAM_SAFE=1
in "append to C/C++" and "Link".
And I also try in "C/C++ Build Environment" to modify the build.extra_flags.esp32 variable from -DARDUINO_USB_CDC_ON_BOOT=0 to -DARDUINO_USB_CDC_ON_BOOT=0 -DCONFIG_ADC_CONTINUOUS_ISR_IRAM_SAFE=1 -DCONFIG_GDMA_ISR_IRAM_SAFE=1

[jantje]

-DUSE_CONFIG_LIB_FILE -DCONFIG_ADC_CONTINUOUS_ISR_IRAM_SAFE -DCONFIG_GDMA_ISR_IRAM_SAFE
So it is correct.

And that is how far my knowledge goes. I mean Sloeber creates commands based on the Arduino framework and if these commands are compliant with expectations there is little I can contribute because I do not know many boards.

They are talking about the Kconfig file.

After taking a quick look at the link it looks to me they have designed a tool to create a file that should be put in the root of your project. The page states.

After being updated, this configuration is saved in the sdkconfig file under the project root directory.

I assume this is a way around the fact that arduino IDE does not support command line modification next to the menu options.
As IMHO EPS32 does quite a bit of hocus pocus I would try the Kconfig file as they propose. If this works your project should also remain compatible with the arduino IDE which is not the case when you use "append to C/C++".

The problem is that my program continue to crash with this message:
Guru Meditation Error: Core 1 panic'ed (Cache disabled but cached memory region accessed).
This message indicate that ADC functions are not in IRAM.

As stated above. I have no clue about this very board specific behavior.

[GitHubLionel]

I try to directly add this two lines:

#define CONFIG_ADC_CONTINUOUS_ISR_IRAM_SAFE 1 
#define CONFIG_GDMA_ISR_IRAM_SAFE 1

in sdkconfig.h files in dio_qspi and qio_qspi include directory but with no more success.

In Kconfig.projbuild, I can read this paragraph:

config ARDUINO_ISR_IRAM
    bool "Run interrupts in IRAM"
    default "n"
    help
        Enabling this option will Attach all interrupts with the IRAm flag.
        It will also make some HAL function, like, digitalRead/Write and more
				be loaded into IRAM for access inside ISRs.
				Beware that this is a very dangerous setting. Enable it only if you
				are fully aware of the consequences.

I need a way to change the default "n" to "y". But how, that's the big question !

That is a question for the esp community. If you know how to do it in the Arduino IDE we can see how to get it working in Sloeber.

[GitHubLionel]

Ok, I found the response in the FAQ of Espressif.
And this paragraph say that modify sdkconfig.h files is without effect:
Note that modifying sdkconfig or sdkconfig.h files found in the arduino-esp32 project tree does not result in changes to these options. This is because ESP-IDF libraries are included into the arduino-esp32 project tree as pre-built libraries.
So no way without ESP-IDF.

[jantje]

This is because ESP-IDF libraries are included into the arduino-esp32 project tree as pre-built libraries.

So the questions are:

1. Is the variant you want delivered/available (Third party library or so) in the arduino framework?
2. and if not: can you build the libraries from source in the arduino framework?

[GitHubLionel]

1. Is the variant you want delivered/available (Third party library or so) in the arduino framework?

Not in the Arduino framework. In fact, it is strange that continuous ADC is provided but is unusable because the directive ARDUINO_ISR_IRAM is not activated.

2. and if not: can you build the libraries from source in the arduino framework?

I don't think so. There are some tools but it is out of my knowledge. We really need to use the "menuconfig" of ESP-IDF.

[jantje]

As ESP32 has a gazillion boards I would assume they have a board with this option.
If not ... they could have.
Anyway it does not seem as a Sloeber issue so I think this issue can be closed.

[GitHubLionel]

Yes, not a Sloeber issue. Maybe a future enhancement but probably hard to code ;)
