Re: (POWERON_RESTE) Looping Boot Issue

Check that your power supply is table and able to deliver enough current. Also check bootstrap GPIOs, esp. the one that sets the voltage level for the flash so that it has proper pull-up/down during boot.

Re: CMake with CLion - working!

What's the current status of this? I'm keen to test out the state-of-the-art and help if i can... It's shaky at best. I don't know why, but sometimes CLion simply loses the xtensa toolchain so it is no longer selectable. I'm currently compiling using command line instead. Also, in adition to the ab...

Re: Asynchronous webserver with websockets

May I ask why you need it to be asynchronous? Also, in what part of the server do you need it? Do you just need multiple simultaneous connections? Keep in mind that the wifi & lwip tasks takes up quite a bit of resources, leaving you less than two cores for your own work. If you're thinking you want...

Troubleshooting SSL_ERROR_BAD_MAC_ALERT

Now that I've finally found the issue with MPI acceleration causing my task to hang I can move on to my other issue; namely Message Authentication Code failure. The setup is the same as previously; code works fine on native Linux, but as soon as it is brought over to ESP32, I get this: mbedtls_ssl_h...

Re: mbedTLS on ESP32 vs Native Linux

After further digging, I've found that when MPI (bignum) hardware acceleration is enabled this hang occurs.

When MPI (bignum) acceleration is enabled, the hang also happens in the ESP-IDF https_server example.

mbedTLS on ESP32 vs Native Linux

I'm debugging two issues with mbedTLS that only happens when running the code on ESP32, i.e. only the mbedTLS adjusted for ESP has this issue. The first issue is that I get this error when connecting with curl/FireFox: mbedtls_ssl_handshake returned -29056: SSL - Verification of the message MAC fail...

Personally I wouldn't draw that conclusion. Even Espressif says to obtain a license, as by the first post in this thread. Ask a lawyer.

Re: CAN License

Note that the ESP32 implements the "classic" CAN, not CAN FD. Still, the document clearly states a license is required for both of them, does it not? Important Notice The CAN Protocol and CAN FD Protocol are developed by the Robert Bosch GmbH and protected by intellectual property rights. The CAN P...
