C6 will not be supported until ESP-IDF 5.1, so arduino will not support it until that is released.

[VojtechBartoska]

Hello, support of ESP32-C6 is on our Roadmap, @lbernstone is right that it will be supported in ESP-IDF 5.1 so in Arduino, it will be in version 3.X.X. We'll soon create development branch and we will start working on IDF 5 support there.

@probonopd Thanks for opening the issue, we will use it to track progress on support of ESP32-C6 :)

[tuct]

My first esp32 c6 dev boards v0.0 arrived today, eager to test it!

[simogaspa84]

Hi @tuct how did you get it the esp32 c6 dev board? which supplier ? thanks

[negis02]

mine also just arrive, i ordered from there: https://www.aliexpress.com/item/1005005125343088.html?spm=a2g0o.order_list.order_list_main.29.28e41802T3MZjD

[simogaspa84]

Thanks a lot @negis02 .. very kind... are you going to try the new features about cyber security in the C6 dev board? I am really interested about the trusted execution enviroment and the glitch detector.. Do you know something about that? Thanks

[seajhawk]

Hey @simogaspa84 - thanks for posting. I'm mainly interested in the Thread support, but I'll have to look at the trusted execution and glitch detector features. I wasn't even aware of those!

I'm building an air quality, temp, humidity, CO2 sensor.

Does anyone know if we can use a C3 board for basic prototyping until the C6 support is added?

[tuct]

I got mine from the official store at aliexpress € 9,81 1%OFF | ESP32-C6-DevKitC-1 Entwicklung Bord Espressif Systeme ESP32-C6 Serie Probe Limit 2 stücke pro Kunden * (siehe beschreibung) https://a.aliexpress.com/_mLI99g2 I bought 5, so the limit is new, happy to share of you are close to or in Vienna

[negis02]

For me most interesting to try ESP32-c6 in Wi-Fi 6 network, to test all WiFi6 benefits: in some application test and compere real time messaging over Wifi6 in is heavy loaded Wi-Fi with many devices, like MU-MIMO and OFDM AP capability tests with IOT device like this; and another test: battery life: Wifi6 wake-up timers test with esp32-c6.

[Trevo525]

You can also purchase from Adafruit's official store. They have 47 in stock at the time of writing this.

46 now, I bought one. 😝

[a-d-r-i-a-n-d]

I've ordered mine today, looking forward to C6 support.

[MingyaoLiu]

I just got my esp32-c6 wroom module, looking forward to have arduino capability!

[guumeyer]

I just got my esp32-c6 wroom module too, looking forward to have arduino capability!

idf.py --version ESP-IDF v5.1-dev-3710-gacac972f70

It looks like v5.1 has been released ;-)

[me-no-dev]

It has not. This is just the version that will be used in the future. 5.1 is in ESP-IDF master and needs to be split in it's own branch before it will be released. It has not even been feature-frozen yet :)

[noonien]

Any update on this?

[djmjr77]

Update please?

[me-no-dev]

Guys, please stop asking for update every few days. Before we add support for new chips, there is a lot of work that needs to be done. When that is done (will take way more than few days) most if not all new chips will be supported. We will announce that, so even less reason to keep asking.

@probonopd Thanks for opening the issue, we will use it to track progress on support of ESP32-C6 :)

As noted, the official Espressif ESP-IDF v5.1, which is currently in development, will include initial support for the new ESP32-C6 chip, however, while Espressif ESP-IDF v5.1 has not yet been released it should mostly work if using the master branch in esp-idf repository. If you want to track the development status then follow these the updates made to these other issues for ESP32-C6:

[LenReinhart]

Another waiting for C6 support. Subscribed.

[SuGlider]

Ok, we have C6 support already. You can try the C6 branch: https://github.com/espressif/arduino-esp32/tree/feature/esp32c6-support

[SuGlider]

This the initial stage of support. At this time we are working in testing and fixing.

UART is fully tested and everything works correclty, including using UART with setCpuFrequencyMhz() at 160, 80, 40, 20 and 10MHz.

The same for RMT.

[SuGlider]

I have tested the Basic WiFi and BLE examples and those are working fine with the current C6 branch. At this point, please, don't expect to see low power consumption yet.

We still must work on the IDF Power Management component of the Arduino Core for the ESP32-C6. It will take some time, but we expect to offer similar IDF results to the Arduino Users related to power consumpion in IoT applications with the C6, and maybe also for other SoCs.

Especificaly for the C6, we will also work on the WiFi 6 (802.11ax), adding an Arduino API for controlling the TWT (Target Wait Time) configuration.

Some IDF examples using the above referenced IDF APIs:

IDF Power Management Example: https://github.com/espressif/esp-idf/blob/master/examples/wifi/power_save/README.md

How do I integrate this with the Arduino application?

[lbernstone]

@LenReinhart This is a very early release. It is intended for the people that will build those pieces. As suglider says, it will take some time.

[SuGlider]

How do I integrate this with the Arduino application?

If you are talkiig about how to "install" the C6 Arduino Core branch, it is necessary to use it as a sketchbook board by cloning this branch into the local Sketchbook Folder. The process of cloning and creating the sketchbook board is described in this link:

https://docs.espressif.com/projects/arduino-esp32/en/latest/installing.html#how-to-update-to-the-latest-code

[LenReinhart]

Understood. I have a copy of Dr. Ting’s Forth that was designed for the ESP32 dev board. It uses Arduino to build the image download. I correctly guessed that the front end would be as much the same as possible on the compiler and it would take care of the translation. I successfully compiled and loaded it on the C3 dev board simply by changing the target. I have two of the C6 boards and would like to see if it will work for that. If it doesn’t no big deal. Bluetooth did not work, but I didn’t expect it would as it was the LE version. I’m 76 and have been working with computer systems since the 8080, now I just like to mess around with stuff and I thought what was done with using the Arduino system, to build and install a copy of Forth OS, I thought was very clever. The fact that it has the possibility of being very transportable among processors using the same compiler and the way the Arduino system takes care of the addressing differences between hardware is very nice IMO.

C6 will not be supported until ESP-IDF 5.1, so arduino will not support it until that is released.

@lbernstone ESP-IDF Release v5.1 has been released.

@lbernstone ESP-IDF Release v5.1 has been released.

Any news here?

[lbernstone]

Pre-release support as shown in the table above is in the idf-v5.1 branch

[VojtechBartoska]

Hello, we are now collecting feedback on release 2.0.11 and when we are good to go, above mentioned branch https://github.com/espressif/arduino-esp32/tree/esp-idf-v5.1-libs will be merged into master and initial support for ESP32-C6 & ESP32-H2 will be available for development purposes.

[petergjoel]

@VojtechBartoska in HardwareSerial.cpp I find #define RX1 5 and #define TX1 4 for UART1 (LP_UART pins) - this is conflicting with the documentation.

However, using the #define RX1 5 and #define TX1 4 works fine for our application -- as long as we flip the wiring accordingly.

See https://github.com/espressif/arduino-esp32/pull/8477

Hi all, I have successfully flashed the ESP32-C6 using https://github.com/espressif/arduino-esp32/tree/esp-idf-v5.1-libs. Using ble Unified Provisioning I got Configuration mismatch. Select BLE Only or BTDM mode from menuconfig, this error does not occur on the ESP32-S3 using the same build. I wish to continue to use Arduino IDE and not setup platform io.

Looks like this is a problem upstream. There are no CTRL_MODE settings in C6 menuconfig. @HX2003 What library/example is using that function?

[HX2003]

@lbernstone I am directly invoking from esp idf #include <wifi_provisioning/scheme_ble.h> #include <wifi_provisioning/manager.h> Although I assume this problem would also occur if one uses libraries/WiFiProv/examples/WiFiProv as well.

[IsraelMek]

Hi, I have added ESP32 core 2.0.14 to the boards manager. Even though in github ESP32-C6 is mentioned on the list of supported boards, it does not show up in the selection list of Arduino.

[me-no-dev]

@IsraelMek you need 3.0.0 for that. It is still in beta and you need to use different BoardManger URL to get it: https://espressif.github.io/arduino-esp32/package_esp32_dev_index.json

[IsraelMek]

@me-no-dev Thanks a lot . Update done to 3.0.0 and I can see ESP32-C6 in the board selection. But it doesn't compile the builtin examples when C6 is selected. it displays error message "bits/c++config.h: No such file or directory". For ESP32-S3, the IDE compiles the example codes without any issue.

[me-no-dev]

It seems that Arduino has some problems extracting the toolchains properly... especially riscv one. Will investigate Monday and come back. You could open the json in the link and download and manually install the toolchain till then

@me-no-dev The manual installation fixed it. Thanks once again.

Same problem on 3.0.0 with C3 and H2.

[me-no-dev]

Same problem on 3.0.0 with C3 and H2.

All RiscV chips currently use the same exact toolchain, so yes. same on C3, C6 and H2

[me-no-dev]

We have found the problem, but not a solution yet. The path to some files inside the toolchain becomes too long for gcc to handle and it does not see the file, though it's there. When installed from git, this issue does not occur, because path is short enough to not trigger it. We do not control where the toolchains are installed, so ... fingers crossed 😆
