Esp32S3 : Is it possible to access the OTA partition where the firmware is running in order to change some bytes ?

Good afternoon, I would like to change some bytes of the OTA partition where my firmware is running in order to create a CRC problem. The goal would be to detect this CRC problem using the function esp_partition_get_sha256. Unfortunately, when I try to write some bytes of the current OTA partition u...

Re: Esp32S3 : Flash Encryption Question.

Good morning, thank you for your answer. Do you think that in development mode, user has the possibility to reflash encrypted and nonencrypted FW unlimitedly ? Especially in the case where non encrypted FW is reflashed directly into the FLASH memory ? In release mode, does this mean that you can jus...

Re: ESP32S3 : Write to the USB/JTAG port does not work properly !

Do you have other ideas please ? When I install the driver, I define the tx and rx buffer size to 256 bytes. (This is not 64 bytes but it worked before). Do you think 64 is the max size I should define ?? When I send datas to the usb_jtag driver do you think I should always but 64 as tx size when I ...

Re: ESP32S3 : Write to the USB/JTAG port does not work properly !

Ok, what is strange is that two weeks ago, printing on the console using usb_jtag_write worked properly. Now, I try with the ESP-IDF 5.1.4 and it dos not work. I have also tried with the 5.2.0 and 5.2.1 version and the result is the same. I don't understand what has changed since two weeks ago. Best...

Re: ESP32S3 : Write to the USB/JTAG port does not work properly !

Could you tell me what is the function to use in order to flush the datas ?
I don't see it in the library.

Or could you please provide me an example to send the 64 bytes of datas at each call of the write methods ?

Best regards,

Esp32S3 : In WIFI access point mode - Is it possible to close a connection manuelly ?

Good morning,

I am using an Esp32S3 in Access Point Mode.

When the access point is started and when a PC connects to it, is it possible to ask for the disconnection from the firmware
manually ?? (My card is the access point).

Thank you for your help,
Best regards,

Thomas TRUILHE
