Okay I'll take a look and try to do the serialesp. Before I switched I wasn't able to get the USB comm port to appear on the LED hardware output path. It was only showing the bluetooth. |

most likely your esp32 doesnt boot (verify on PC, HyperSerialESP32 should provide com port) or you must refresh the output devices |

It looks like everything is being flashed properly but I'm honestly pretty new to ESP boards so I'm not 100% sure. I'm using the ESP32-S2 Lolin mini and I'm pretty confident I selected the right firmware (using Sk6812 RGBs). Still showing only the bluetooth I think?? But the lights reacting now. I tried to use serial monitor on arduino but I'm not confident in how to debug if its booting. I am not seeing anything when I reset the board.

I have already pointed you what test should be performed in HyperHDR to check if the board works. And you keeping damaging your esp32 bootloader (with erase) then loading only standard firmware.... please stick to the HyperSerialESP32 manual. |

I'm sorry I misread your message regarding the firmware. I'm sorry I understand I'm being difficult. Thank you for being patient with me. This is what I attempted. 1st. Had to put the board into dfu mode (cause it wasn't detected) by holding Rst + 0 2nd. Exeuted erase_flash 3rd. Flashed the firmware esptool.py write_flash 0x0 firmware_esp32_s2_mini_SK6812_RGBW_NEUTRAL.factory.bin (only factory this time unlike previous times)
I'm still only seeing ttyACM0 connection. I'm taking a look at the blog post regarding the debugging now. PS C:\Users\coleh\PycharmProjects\PythonProject\ESP Tool\HyperSerialESP32-master\HyperSerialESP32-master> esptool erase_flash Leaving... |

Hello everyone!
Trying to flash my esp32 board (ESP32-S2 Lolin mini) with the firmware for Hyperserial but having no luck. When I run esptool.py write_flash 0x10000 firmware_esp32_s2_mini_SK6812_RGBW_COLD.bin or esptool.py write_flash 0x0 firmware_esp32_s2_mini_SK6812_RGBW_COLD.factory.bin its telling me [Errno 2] No such file or directory:. I'm probably missing something obvious it's my first time trying to flash the board.
Thanks for any help!
Best Regards,
Cole
