I have made a custom esp32 board. For schematic, i have used sparkfun link-
The problem is- the arduino code is not uploading on the custom esp32 board. So, how i can upload the code on esp32?
Is arduino bootloader is required first for bootloading the blank esp32? If yes, then what is the procedure for uploading the arduino bootloader on esp32?

This is a common error when uploading to an ESP32. It is well documented.

Two points raised in the article in the above article. The ESP32 is a 3.3V device. You need an appropriate Serial-to-USB converter. Secondly, during the program upload GPIO0 must be tied to ground!
