Dear all, have a great day! Here I attached a document of communication data between MCU and ESP32-S2-MINI In that document, Communication data present until "Loader Flash Begin cmd", And I implemented upto "Loader Flash Data cmd", After finish the flashing process ESP32 is not waking up, Instead ES...

Hi Buddy, I have attached my received capture, there I was highlighted particular area of data's, which I was receiving particular data in my all of receiving frame. Because of these data only, I suspect these data's only the reason Wi-Fi MCU not waking up after the MD5 verification step. Here I cou...

Hi have a great day! In flashing steps, Currently I have crossed SPI PRAMETERS steps. Now I'm working on flash begin step, I stuck up here, because of I can't able find the proper value of bin size and address. Could please support me for find out the respective value and completing the remaining st...

Note that there are two bootloaders: the first stage lives in ROM and cannot be flashed ever, the 2nd stage lives in the SPI flash and you generally flash that automatically along with your application. Hi ESP_sprite, Thank you for giving this information. If you don't mind, Could please some more ...

It would be easier for us to help you if you explained what you would like to achieve, instead of asking for pieces of technical information. Your diagram above is correct. Here is the documentation on the serial bootloader from esptool. https://docs.espressif.com/projects/esptool/en/latest/esp32/a...

I think you're not understanding how ESP32 chips work. ESP chips or modules don't have their own flash on-silicon; they must be paired with some kind of SPI flash that contains the program they run. That flash can be either in the chip package or in the module or added externally. That is what 'SPI...

What is your question? Have you looked at https://github.com/espressif/esp-serial-flasher already? I have referred the given example code of stm32_example, In that UART transmission is making conflict with SPI and incomplete code, even in SPI transmission final transmit function is missing can't ab...

Can you share the ESP32-S2 mini serial programing protocol document for understating the code flow? Please share the document.
