Cannot Run ESP32C6-devkitm

[FelipeMdeO]

Hello all,

I am trying use Nuttx in ESP32C6-devkitm. I followed the tutorial: https://nuttx.apache.org/docs/latest/platforms/risc-v/esp32c6/index.html Below you can se my outputs: ~/nuttxspace/nuttx$ make bootloader Using direct bootloader to boot NuttX. `riscv-none-elf-ld: warning: /home/felipe-moura/nuttxspace/nuttx/nuttx has a LOAD segment with RWX permissions CP: nuttx.hex MKIMAGE: NuttX binary esptool.py -c esp32c6 elf2image --ram-only-header -fs 4MB -fm dio -ff 80m -o nuttx.bin nuttx esptool.py v4.8.dev4 Creating esp32c6 image...

Hi,

Seems you are using direct bootloader, you don't need to use make bootloader command. Please apply these steps:

make distclean
./tools/configure.sh esp32c6-devkitm:nsh
make
# ESPTOOL_PORT value might change
make download ESPTOOL_PORT=/dev/ttyUSB0
# picocom ...

If problem still happens, please inform and please include compiler and other tool versions (nuttx and nuttx-apps) you are using.

Hello @eren-terzioglu , thank you for help me. Issue still happens: Please, look file attached, there I put the terminal output term_out.txt

About my configs: I am working inside nuttx docker: https://github.com/apache/nuttx/blob/master/tools/ci/docker/linux/Dockerfile I clonned nuttx using: https://developer.espressif.com/blog/nuttx-getting-started/

I tested with an esp32c6-devkitm with this specs and it is working well (only difference is revision 0.0 -> 0.1):

esptool.py v4.8.dev4
Found 2 serial ports
Serial port /dev/ttyUSB0
Connecting....
Detecting chip type... ESP32-C6
Chip is ESP32-C6FH4 (QFN32) (revision v0.1)
Features: WiFi 6, BT 5, IEEE802.15.4
Crystal is 40MHz

Are you using USB port or UART port? Seems you are USB port, please change it to UART port.

[FelipeMdeO]

You are right, I was using wrong usb connector. After change for UART port it is working properly. Thank you.
