I just received my Thing Plus ESP32-S3. When first powered, the RGB LED faded between colors. I set the board and settings following the instructions on the “Arduino Examples” page. I doubled check the board types and made sure the changed settings matched. I left all other setting as is. I tried the “RGB Example” and it compiled and downloaded without error. The board did not work properly after the download. The RGB LED was a steady green. I opened the Serial Monitor and got a rapidly repeating error message. It appears the this line in the error message shows the problem: E (137) rmt(legacy): CONFLICT! driver\_ng is not allowed to be used with the legacy driver Can you help me fix this problem? Thanks very much for your help. ## The full serial output is below: Rebooting… ESP-ROM:esp32s3-20210327 Build:Mar 27 2021 rst:0xc (RTC\_SW\_CPU\_RST),boot:0x18 (SPI\_FAST\_FLASH\_BOOT) Saved PC:0x40378071 SPIWP:0xee mode:DIO, clock div:1 load:0x3fce3818,len:0x109c load:0x403c9700,len:0x4 load:0x403c9704,len:0xb50 load:0x403cc700,len:0x2fd0 entry 0x403c98ac E (137) rmt(legacy): CONFLICT! driver\_ng is not allowed to be used with the legacy driver abort() was called at PC 0x4200920b on core 0 Backtrace: 0x40377a5e:0x3fceb200 0x4037c8dd:0x3fceb220 0x40382471:0x3fceb240 0x4200920b:0x3fceb2c0 0x4200cee6:0x3fceb2e0 0x40377d63:0x3fceb310 0x403cdb0a:0x3fceb340 0x403cdea1:0x3fceb380 0x403c9919:0x3fceb4b0 0x40045c01:0x3fceb570 0x40043ab6:0x3fceb6f0 0x40034c45:0x3fceb710 ELF file SHA256: 126c11852c22b594 E (166) esp\_core\_dump\_flash: Core dump flash config is corrupted!

The error you’re encountering is related to a conflict between different versions of the RMT (Remote Control) driver in the ESP32-S3. The message “CONFLICT! driver\_ng is not allowed to be used with the legacy driver” suggests that there’s a mismatch between the driver versions being used. To resolve this issue, you can try the following steps: 1. Update your ESP32 Arduino core: Make sure you have the latest version of the ESP32 Arduino core installed. You can do this by: 2. Check your code for RMT usage: If you’re using any RMT-related functions in your code, make sure you’re consistently using either the legacy or the new generation (ng) version, not both. 3. Modify the Arduino JSON files: If the problem persists, you might need to modify some configuration files: 4. Use a different LED library: If you’re using a specific LED library that might be causing this conflict, try using a different one or implement the LED control manually. 5. Check board settings: Ensure that you have selected the correct board in the Arduino IDE: - USB Mode: Hardware CDC and JTAG - USB CDC on Boot: Enabled - Upload Mode: UART0 / Hardware CDC - PSRAM: QSPI PSRAM are all set 1. Try a simple blink sketch: If the problem persists, try uploading a simple blink sketch without using the RGB LED to see if the board is functioning correctly otherwise ---

This was not a program I wrote but the “RGB LED Example” sketch provided on the Sparkfun Thing Plus ESP32-S3 examples page at: [https://docs.sparkfun.com/SparkFun\_Thing\_Plus\_ESP32-S3/arduino\_example/#thing-plus-esp32-s3-github-repository](https://docs.sparkfun.com/SparkFun_Thing_Plus_ESP32-S3/arduino_example/#thing-plus-esp32-s3-github-repository) This sketch was written by: ```auto By: Nathan Seidle SparkFun Electronics Date: January 13, 2024 ``` I verified that my ESP32 board was the latest revision 3.0.4. I also made sure all the libraries were up to date including the FastLED library at revision 3.7.7. I could not find the json file you mentioned at the path: “C:\Users[YOUR\_USER\_NAME]\AppData\Local\Arduino15” so I was unable to modify: “#define SOC\_RMT\_CHANNELS\_PER\_GROUP (1)” I did verify that the blink sketchran correctly but the LED did not blink since only the RGB LED was present. I added some print statements and verified the code was executing properly. Could you check with Nathan and see if he has any suggestions to get his sketch to work. ---

I have some additional information. The problem appears to be in the FastLED library. I get the same error with several of the example sketches supplied with this library. I tried using the “Adafruit NeoPixel” version 1.12.3 library based on a Google suggestion and this library appears to work. There appears to be several libraries that are variants of the FastLED library. I am using version 3.7.7 which is the latest Arduino update. **Could you tell me which version of the FastLED library Nathan used?** ---

Going purely by the date (Jan 2024) [my first guess is 3.6](https://github.com/FastLED/FastLED/releases) - try that and see if it improves things…not sure if you’d need the ESP-IDF from that same time period or not [(4.7?)](https://github.com/espressif/esptool/releases/tag/v4.7.0) Give those a try as a last resort and I’ll try to poke Nathan if that doesn’t work 🙂 ---

I first tried using FastLED version 3.7.7 with an original ESP32 chip in a DOIT ESP32 DEVKIT V1. The program compiled and loaded into to board without error. All I got was the ESP32 boot messages followed by my starting println(). I did not get any run time errors. I did not have a WS2812B to test that the board was generating the correct output but things looked good. I next downgraded my FastLED library to version 3.6.0 and tried to compile the sketch. I got a large number of errors having to do with missing variables, etc. I tried FastLED version 3.6.0 with both the ESP32-S3 and the ESP32. Both gave similar error messages except that the ESP32-S3 had two additional blocks of error messages toward the end of error messages. It is likely that I would need to downgrade a number of libraries and possibly the board definitions to get FastLED version 3.6.0 to compile. I have attached the ESP32-S3 error messages for FastLED version 3.6.0 below. I can send the ESP32 error message if you would like.

I suspect you are right…or test on a fresh separate PC/laptop, or create a backup copy of the arduino15 folder and wipe the main one to begin anew…are either of those workable? ---

I actually installed the Arduino IDE from scratch so things should be good. I have tried several other WS2812 libraries and they worked fine. Is there any chance Nathan Seidle would have time to identify which version of the FastLED he used. ---

I sent a message - give it a few days and hopefully we’ll know more soon 🙂 ---

So, I’m unsure as to whether I’d consider this good news or not at this point, but: ![image](https://canada1.discourse-cdn.com/sparkfun/original/2X/6/645650ded3f83c8a72655d9f22413e3c192e2fe8.png) ---

Sadly, i tried downgrading FastLED to version 3.6.0 but I got a lot of compile errors. I listed these in a previous post. I suspect I would need to downgrade a large number of libraries to use version 3.6.0. I had been using FastLED version 3.77 for most of the tests. They recently updated it to 3.7.8 and I repeated the tests. The code still compiles but I get the same abort code when the ESP32-S3 tries to run it. I would suggest removing the FastLED library example from your example code since it fails with later versions of FastLED. You can add it back when it is working. ---

I’m getting the same results (green when it should be black and other weirdness) Adafruit Neopixel library works so I will go with that for now. Arduino IDE 2.3.3, fastled 3.9.2, adafruit neopixel 1.12.3. i didn’t try older versions of FastLED
