Hi,

1. A Serial Flasher utility for Espressif chips. Program Baudrate: Connected to device: Flash Address Selected File Remove; Remove: Console Connected to.
2. 2.2.2 ESP FLASH DOWNLOAD TOOLS This is the official tool for updating the firmware of ESP8266EX. The tool is maintained by “Espressif Systems”. Download and extract the latest version of “FLASH DOWNLOAD TOOLS” from the official Espressif web-site. The archive is usually located under “Tools” sub-group at the web-page with the ESP8266EX.

The ESP32 Flash Download Tool, just like the ESP8266 download tool, is the official Espressif Download tool that runs on Windows platform. The tool can be used to modify and generate init BINs, generate consolidated BIN files or program multiple chips for production runs. The tool uses COM port to send BIN files from PC to the ESP32, which then.

I've been always using Arduino IDE to load firmware to my ESP32 device, but recently I need to switch over to the ESP32 Download Tool. I have a hard time to find/fill in the Bootloader and Partition Bin files and their addresses, hope someone can help provide some hints or guideline.
This is my Arduino Set Up for my custom board:
*Board: ESP32 Dev Module
*Upload Speed: 115200
*Flash frequency: 40Mhz
*Flash Mode: DIO
*Flash Size: 4MB
*Partition Scheme: Minimal SPIFFS (since I use BLE and Wifi for OTA update, which need more memory space)
For the ESP32 Download Tool (see my attached picture)
1. For the bootloader:
I did try to use bootloader_qio_40m.bin at the address 0x1000
-> I got the file from Arduinohardwareespressifesp32toolssdkbin
-> For the address, I am not sure which one to put there so I use a random address that I found online, where other people use it.
-> I got an IO error saying the bootload is not available in the flash download tool folder.
IOError: [Errno 2] No such file or directory: u'C:...Programmer Softwareflash_download_tools_v3.6.5_0flash_download_tools_v3.6.5flash_download_tools_v3.6.5dl_temp/_temp_by_dltool/downloadPanel1bootloader_qio_40m.bin_rep'
2. For the partition:
I have min_spiffs.bin at the address 0x4000
->I used Python to generate the bin file from the min_spiffs.csv from the folder Arduinohardwareespressifesp32toolspartitions
-> Same as the bootloader's address, I really don't know what to use for the partition address.
3. For my firmware:
I have the .bin file generated by Arduino, address at 0x10000. It looks like this is a valid address.
Any thoughts?
