--- Comment #12 from Tomoyuki Sakurai <trombik1...@gmail.com> --- while trying different development boards (mostly newer ones), I found some issues. esptool.py --chip esp32s3 -p /dev/cuaU0 -b 19200 --before=default_reset --after=hard_reset write_flash --flash_mode dio --flash_freq 80m --flash_size 2MB 0x0 bootloader/bootloader.bin 0x10000 blink.bin 0x8000 partition_table/partition-table.bin esptool.py v4.8.1 Loaded custom configuration from /home/trombik/.config/esptool/esptool.cfg Serial port /dev/cuaU0 Connecting...................................... A fatal error occurred: Failed to connect to ESP32-S3: No serial data received. For troubleshooting steps visit: https://docs.espressif.com/projects/esptool/en/latest/troubleshooting.html lowering baud rate does not help. when manually set download mode by pressing the reset button while boot button is pressed, I got: esptool.py --chip esp32s3 -p /dev/cuaU0 -b 19200 --before=default_reset --after=hard_reset write_flash --flash_mode dio --flash_freq 80m --flash_size 2MB 0x0 bootloader/bootloader.bin 0x10000 blink.bin 0x8000 partition_table/partition-table.bin esptool.py v4.8.1 Loaded custom configuration from /home/trombik/.config/esptool/esptool.cfg Serial port /dev/cuaU0 Connecting..............................

A fatal error occurred: Failed to write to target RAM (result was 01070000: Operation timed out) this issue looks similar to me: https://github.com/espressif/esptool/issues/280 while writing does not work, reading serial outputs works fine. -- You are receiving this mail because: You are the assignee for the bug.
