Re: Declaration of capacitance and inductance (for ESP32-WROVER-EM213EH2864PH3Q0 module)

I already tried sending a message through the ESP Sales page (https://www.espressif.com/en/contact-us/sales-questions) but haven't received any response, or even an acknowledgement, to my inquiry in 2 weeks.

I will try emailing the sales team as you have suggested.

Thanks,
Aary

Declaration of capacitance and inductance (for ESP32-WROVER-EM213EH2864PH3Q0 module)

I am looking for a "Declaration of maximum capacitance and inductance" for the ESP32-WROVER-EM213EH2864PH3Q0 module from Espressif to support certification. A declaration of the lumped total capacitance and inductance of the ESP32 is what I am looking for. There was a similar inquiry here about a TI...

Re: Is the ESP32 IDF Non-volatile memory (NVS) integrity checked (CRC32 or checksum) between boots?

I'm decently sure the CRC is checked on read of a NVS item; if the CRC does not match, the item is not seen as valid and will be skipped. As NVS is effectively a journalling FS, this means it will use an older value if available, or returns the item cannot be found if not. Thanks a lot for this rep...

Is the ESP32 IDF Non-volatile memory (NVS) integrity checked (CRC32 or checksum) between boots?

Is the (NVS) flash memory on board the ESP32 integrity checked between boot-ups? The structure of entry into the NVS memory for ints, strings and blobs contains a CRC32 checksum over the bytes in the entry (apart from the CRC field itself) according to the espressif documents, but there is no mentio...
