Cannot flash firmware, A8 not showing as connected serial device - kcampbell - 09-28-2024
I use a Mac, and do not have access to Windows PC
When powering on the A8 I hear the series of relay clicks and the power light is on.
I have connected USB C to C cable to my MacBook, but "ls /dev/cu.*" does not show any connected device and so I cannot flash firmware.
Any suggestions?
Kevin

2. You can use Python tool download ESP32 firmware:
step-1:
Install esptool: Open Terminal and run:
pip install esptool
Connect ESP32: Connect your ESP32 via USB, then find the device port:
step-2.
ls /dev/cu.*
Erase flash (optional):
step-3.
esptool.py --port /dev/cu.SLAB_USBtoUART erase_flash
Flash firmware: Replace with the actual port and firmware file path:
step-4.
esptool.py --chip esp32 --port /dev/cu.SLAB_USBtoUART write_flash -z 0x1000 your_firmware.bin
