First Firmware Writing of ESP32-D0WDQ6
I'm going to develop a new product with ESP32-D0WDQ6. How do I write firmware to the chip for the first time? Must we use JTAG mode, or just use UART, the same way as the development board writes?

Yes, first time firmware upload is no different from the rest, and can be done over serial port ("make flash" or "idf.py flash", if using CMake build system, or using esptool.py). ROM bootloader responsible for serial uploads is always present on the chip and cannot be erased.
