Hi, We have enabled Secure Download mode on our ESP32-S3. After, we tried to read our flash with the following parttool (esptool) command, but as you can see, this failed: $ parttool.py --port /dev/ttyACM0 --partition-table-offset 0x10000 --esptool-args="after=no_reset" --esptool-args="no-stub" read...

Hi all, The ESP32 modules allow for a wide range of output power levels. For example, the ESP32-S3 allows an output power up to 21 dBm for both WiFi and BLE. When using the ESP32 in a product, we will be bound by local regulations of course. We are wondering if Espressif or any users here have guide...

Hi, I did some out-of-the-box WiFi testing with the espressif iperf example, between 2 ESP32-WROVER-E's (part of the ESP32-Ethernet-kit_A_V1.2) and similarly between 2 ESP-S3's (part of ESP32-S3-DevKitC-1 v1.0). I wanted to test the throughput between 2 identical modules, so the simple setup is as f...

Thanks for the clear answer!

Hi all, I am confused about the two events UART_BUFFER_FULL and UART_FIFO_OVF. What is the exact difference between these two events: what do they represent, when do they occur and especially to which RX buffer do they apply ? The documentation on UART ( https://docs.espressif.com/projects/esp-idf/e...

Hi,

Any updates regarding how to enable the "Permanently switch to Secure mode (recommended) option?" and if UART/ROM Download Mode is automatically enabled/disabled in flash encryption release mode?

Thanks in advance,

Hi,

It would be great as some of these questions could be answered by the ESP WiFi team, as I agree that documentation on this is quite contradictory.

Kind regards,

Thanks for the help, I appreciate it. (Hm, did you post this question earlier as well? I'd swear I saw it before...) Indeed, I removed that question and trimmed it down to make it more manageable, as I realized the entire thread was too bulky. I'm not a secureboot expert, so I'll leave the majority ...

Hi, After enabling several security features of our ESP32-D0WD-V3 (revision 3) ESP32, I have some questions regarding the download modes possibilities of the ESP. We enabled flash encryption and secure boot V2 on our device, while trying to keep the possibility of reflashing it. These are my questio...
