bin2hex for ESP32 microcontrollers?

Hello!

Is there a ready-made tool for generating * .hex files from * .bin files for ESP32 microcontrollers?

Re: Is it possible to read data from the flash memory at the given addresses during the operation of the ESP32 firmware?

Thanks for the answer. Yes, I meant it. I need to read data from the same flash chip with which the ESP32 microcontroller loads. I have to read the data from the first sector of this chip located at addresses 0x0000 - 0x8000. Read data is pre-written there by the STM32 microcontroller before turning...
