ESP32 Forum

1. i entered into the bootloader following([esp32c3 bootloader][/https://docs.espressif.com/projects/esp ... bootloader])

2. I have followed the UART protocol [Serial Protocol][/https://docs.espressif.com/projects/esp ... tocol.html]

3. then I used MEM_BEGIN, MEM_DATA command so that i can get response.
4. I received Response from the ESP UART without any error [response][/https://docs.espressif.com/projects/esp ... nse-packet]

you can see the picture for the MEM_DATA received Response
[img][/MEM_DATA_received_Response]. This received MEM_DATA Response did not have any error.


However, the problem is: the data is not flashed into the ESP32 ROM.
Note: starting flash address was 0x00000000

Do you have any idea why the data is not written in the Flash?

Thank you in advance.

That is because, according to the docs you provided, MEM_DATA loads data to RAM, not flash. Btw, we have existing flashing code in C, if that's what you need.
