Some time (this time after flashing, but I think it also happens on normal reboots), the ESP32 will just perform the first steps of the boot and hang and never go any further. This isn't an UART configuration problem since all messages that I get are t...

You will need a little bit more than esptool for that. You can use the utility mentioned by Zeni241 or make your own. The tool to generate NVS partitions from their CSV definition is nvs_partition_gen.py located in esp-idf/components/nvs_flash/nvs_partition_generator/ . So you basically have two cho...

Okay thanks for the quick reply, that's what I thought

Hello, Reading the docs concerning the partitions for the ESP32 https://docs.espressif.com/projects/esp-idf/en/v3.1.2/api-guides/partition-tables.html , I read the following test (0x2) is a reserved subtype for factory test procedures. It is not currently supported by the esp-idf bootloader. . So I ...

So I found myself playing with the configuration of mbedTLS also, and here are the results (the change of configurations are made one of the top of the previous) : Archive File DRAM .data & .bss IRAM Flash code & rodata Total libmbedtls.a 92 264 0 94799 18102 113257 (base version) libmbedtls.a 92 26...

This configuration is in the sdkconfig in "Component config -> ESP32 specific " and the title is "Enable 'nano' formatti...
