Hello All--a few questions about using flash encryption without secure boot: If I serial flash a binary with flash encryption enabled (i.e. "in make menuconfig, navigate to “Security Features” and select “Yes” for “Enable flash encryption on boot”."), and then write-protect the FLASH_CRYPT_CNT efuse...

Would it be possible to use linker script generation https://docs.espressif.com/projects/esp-idf/en/latest/api-guides/linker-script-generation.html to place all of the esp-idf "system" in one portion of the memory, then place the user function code in another portion of the memory, and only perform ...

Hello, are you developing in arduino-esp32? Since you are coding for sockets, and the console output shows a failure to bind a new socket after successfully binding the socket for the first time, perhaps the code should destroy the socket each time it finishes the for loop. You could also checkout t...

Thanks much, kolban . As of now, I do plan to downsize my factory app and factory app partition to less than the size of the ota apps and ota partitions, to give me more room in flash for the larger ota apps. Decreasing the size of the ota apps in order to decrease ota time in the field is also a pr...

Hello, Is there a method in the ESP32 IDF to "partition" the flash memory space to store the user-coded code separately from the ESP32 "system" code (e.g. all the code in esp-idf/components), and realize the capability to ota the user code and system code separately? My code is about 1.2 MB currentl...

Thanks for the tips ESP_igrr--the verbose output is very helpful. I am not sure which version of the ESP32 IDF I have, but I cloned it from git on 17 Nov 2017, if that helps, and I have not updated since. Is there a command line method to check the version? Here is the verbose output using the sd ex...

Hello, I am using an ESP-WROOM-32 to test the interface to different SD cards, using the sd_card_example_main.c example from the ESP32 IDF. The interface works with an 8 GB SDHC card, but when I try it with a 128 MB micro SD card and see the following error: E (244) sdmmc_cmd: sdmmc_card_init: send_...

Hello,

Is there an ESP32 IDF software command to enter download boot mode?

Thanks.

Hello tuskiomi, I had an issue with python versions on Windows for running eclipse_make.py in which python v3 on my machine would throw an error like this: 07:04:00 **** Incremental Build of configuration Default for project wakespy **** py -3 D:/ESP32_Projects/ESP32-IDF/esp-idf/tools/windows/eclips...

I think I figured it out: Enable the Overflow interrupt: // add ledc isr register function ESP_ERROR_CHECK( ledc_isr_register(ledc_timer_overflow_isr, NULL, ESP_INTR_FLAG_IRAM , NULL)); // Enable timer overflow interrupt Register 13.17: LEDC_INT_ENA_REG (0x0188) /* description: The interrupt enable ...
