Thanks WiFive...
That was the problem

Hello all,

The problem I am going to describe have been tested on both the latest IDF and the stable 3.2
We got a batch of a hundred boards that we designed around the ESP32.
The modules that are populated, are marked as ESP32-WROOM-32.
The problem we are facing is that when the module wakes up ...

Wrong offset on the burning of the keys.. it should be 0x310000 :oops:

Hello all,

I am working on a second product based on the ESP32 and want to use the NVS encryption mechanism to encrypt
some strings.
When using non-encryption on the NVS these strings are loading correctly.

The encryption ...

Hello,

Does anyone has the BOM of ESP-WROVER-KIT V4.1 ?

I am trying to figure out the external RTC crystal (brand, type, load capacitors etc) that are used on that kit so, I can test the same type
on an ESP32-WROOM-32 board I have designed and face a stability on the behaviour of the RTC ...

Hello all,

The module is an ESP32-WROOM-32 (ESP32D0WDQ6 (revision 1))
On a new product we need to use the RTC for deep sleep wake up, time keeping and sensing some buttons on RTC_GPIOs for forced wake ups from deep sleep.
The problem is that some times the crystal fails to start (?) resulting the ...

Thank you both for the information

I tried the wearleveling example just to check that I could mount and work the fat partition i added in partitions.csv.

hello,

I need to load multiple esp32 devices with different data like certificates, configuration files etc. and encrypted them.

In a previous attempt I tried to use spiffs.. That went pretty much as expected.. easy build and flash
on each esp32..

When I enabled the encryption the spiffs ...

What efuses should I burn ? is that operation reversible ?

Thanks ESP_igrr..

I'll see what I can do.. I have some plain text data in that partition which I would like to be encrypted..

Hello,

I couldn't wait for the new release to come out and tried 86148a740b12b to see how this will go. :)
It worked as expected.. esp_flash_encryption_enabled() returns true and when I dumped the data
I couldn't locate any string that there are in an un-encrypted firmware bin ..

The problem, I ...
