Dear All,
Good Day!
I hope all of you are doing good and Safe.
We have designed our own board using ESP8266EX, I have attached the schematic of the same in this post. Today we have received the assembled board when we were trying to flash the test program to our board using Arduino IDE and via PL2303 - PL2303HX USB to TTL Serial UART Converter Module.
Connection between USB to TTL and Customized board,
USB to TTL Designed ESP8266 board
3.3V 3.3V
GND. GND
TX U0RXD(25)
RX U0TXD(26)
GPIO 0 to GND
When we flash the example program we are getting serial port error (Attached screenshot). Our doubt is, should we need to flash the bootloader first to the ESP8266 or we can flash the test program? If we need to flash the bootloader first how to flash the bootloader on the new customized board.
All your inputs are most welcome and appreciated.
Thank you all in advance.
