Native USB board #8
Comments
If you mean that USB serial you can assign a default console to it by placing file |

Just to confirm I am talking about the usb connection which is directly
connected to the gpio 19 and gpio 20.
Edit: i figured out the cmdline file thingy will try that and tell you how that goes.

USB serial you can make it default console by placing file cmdline with
the following text: earlycon=esp32s3acm,mmio32,0x60038000 console=ttyGS3
debug rw root=mtd:rootfs no_hash_pointers into
build/build-buildroot-esp32s3/target/etc, running keep_buildroot=y
keep_rootfs=y keep_bootloader=y keep_toolchain=y nice
./rebuild-esp32s3-linux-wifi.sh and letting it reflash the board
including the etc partition.

Hey If it's not much trouble could you tell me step by step on how I should
do it. I did it multiple times and the outcome is the same. I am pretty
sure I am doing something silly which I cannot find right now. :(

And if it's not a problem can you tell me how should I change that line
because I am fairly new to it.

You can do it like that with your current directory where the build scripts are: It will run part of the build, prepare new file system images and prompt you to press enter when it's ready to flash the bootloader, kernel and rootfs and again for etc. |

Awesome!! Will try it as soon as possible and get back to you.
Thank you so much

I did everything as instructed but it is getting stuck at a different output. |
|
That looks odd. I only see on the UART. On the USB serial the default build prints the following for me: If you don't see that there's something wrong with the bootloader. |

This was getting print when I installed without any modification to the
cmdline but after that it was stuck there

If you don't see that there's something wrong with the bootloader.
Are you able to get output from any other firmware flashed into your
board? Can you point me to a spec for your board?

Okay so I get this exact output "linux ptr = 0x42120000 |

I suspect that this is the same issue that was found here. Please rebuild your image with the updated bootloader and let me know if there's still no console output. |

All right I will try it and give you update

Hi,
I bought a esp32 board which has no UART connection it only works on the native USB. It gets flashed easily but when I open putty with 115200 baud rate and the correct COM port it is stuck at the very first line "ESP-ROM:esp32s3-20210327". Can someone help me out please?
