Native USB board #8

Open aaryavbehl opened 3 weeks ago

aaryavbehl commented 3 weeks ago

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?

it only works on the native USB

If you mean that USB serial you can assign a default console to it 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.

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.

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:

$ echo 'earlycon=esp32s3acm,mmio32,0x60038000 console=ttyGS3 debug rw root=mtd:rootfs no_hash_pointers' > build/build-buildroot-esp32s3/target/etc/cmdline
$ keep_buildroot=y keep_rootfs=y keep_bootloader=y keep_toolchain=y nice ./rebuild-esp32s3-linux-wifi.sh

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.

aaryavbehl commented 3 weeks ago

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. pp rom version: e7ae62f

jcmvbkbc commented 3 weeks ago

That looks odd. I only see

pp rom version: e7ae62f
net80211 rom version: e7ae62f

on the UART. On the USB serial the default build prints the following for me:

linux ptr = 0x42120000
vectors ptr = 0x4037c000

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?

aaryavbehl commented 3 weeks ago

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

Okay so I get this exact output "linux ptr = 0x42120000 vectors ptr = 0x4037c000" from USB serial when I don't modify any cmdline file and gets stuck at that output only. Its a custom board so it is tough to find the specs for it but I can tell you the chip info. This is the output I get when I run the esptool.py chip_id Connecting... Detecting chip type... ESP32-S3 Chip is ESP32-S3 (QFN56) (revision v0.2) Features: WiFi, BLE, Embedded PSRAM 8MB (AP_3v3) Crystal is 40MHz MAC: f0:f5:bd:4b:f4:0c Uploading stub... Running stub... Stub running...

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.

aaryavbehl commented 2 weeks ago

All right I will try it and give you update
