ESP32 Forum

I have an ESP32C6 connected to COM15 port that doesn’t have a loaded firmware (FW), and I want to load a .bin FW in a non-development environment. I am using this command which seems to execute correctly, but the device remains in a state that does not start:

esptool --port COM15 write_flash 0x180000 C:\Users\efernandez\Desktop\Wifi6_1.00.109.01.bin

I have this partition table:

# Name, Type, SubType, Offset, Size, Flags
nvs, data, nvs, , 0x4000,
otadata, data, ota, , 0x2000,
phy_init, data, phy, , 0x1000,
factory, app, factory, , 0x110000,
ota_0, app, ota_0, , 0x110000,
ota_1, app, ota_1, , 0x110000,

I am trying to load it into ota_0, am I doing it correctly? Is the start address of the ota_0 partition 0x180000? If it’s the first load, should I do it in factory?

The load seems to be correct, I get this result:

However, the device remains in a state that does not respond and does not run the program.

You're only flashing the application code. If your ESP32C6 flash is entirely erased, you'll also need to flash the bootloader and partition table.

The address is also incorrect.
The value will be more close to 0x120000 or 0x130000, but its not the exact number i think.
Factory app partition most likely will be at 0x10000, so it should be 0x120000.

In your case it would be best if you configure factory partition start address.

Thank you very much for your response! I have managed to load everything necessary and in the appropriate flash memory position thanks to your help!

In case anyone is in the same situation, these have been the 4 commands that I have used for the ESP32C6 to load everything correctly:

esptool --port COM15 erase_flash
esptool --port COM15 write_flash 0x0 C:\Users\efernandez\Desktop\bootloader.bin
esptool --port COM15 write_flash 0x8000 C:\Users\efernandez\Desktop\partition-table.bin
esptool --port COM15 write_flash 0x10000 C:\Users\efernandez\Desktop\Wifi6_1.00.109.01.bin
