Yes, pthread yielding (and libstdc++ thread yield on top of that) is implemented and supported. The difference here is in the behaviour of "yield" on a conventional OS (like Windows/MacOS/most installs of Linux) and a real-time OS like FreeRTOS. Yielding in FreeRTOS means "immediately allow a task o...

(Moderator's note: I've split this question to a new topic and moved it out of the News forum.) I'm not familiar with Kafka, but you're correct that sending 21,500 MQTT messages/sec will not be possible on an ESP32. Do you need to send one sample per MQTT message? If you can combine multiple samples...

Probably I don't quite understand how to find the correct version of arduino-esp to use with the official released esp-idf. I think arduino-esp32 tends to track "master" rather than releases. You can tell which ESP-IDF version was used to build the precompiled libraries (used by the Arduino IDE) by...

the trace is showing that WiFiGenericClass::getMode() is somehow overwriting the bounds of its stack (which I find hard to believe). How old is your version of the Arduino repo? There was (technically) a stack smashing bug in this function which was fixed very recently. The type of the "mode" local...

I don't think an issue was ever opened, so yes please open one.

Hi Dmitry, Glad you got everything working. Sorry I didn't think of the digest bug when I first replied. ESP-IDF v3.1 includes esptool v2.5.0, but there's no reason why using IDF 3.0.2 + esptool v2.5.0 won't keep working. I've enabled both secure boot and flash encryption. Now bootloader and app par...

Hi dmitryga, This all looks correct to me. What version of ESP-IDF are you using? (You can check by running "cd $IDF_PATH" then "git describe --tags --dirty") A bug was fixed in esptool v2.5.0 where digest_secure_bootloader could produce an incorrect digest under some circumstances. You can check if...

An update, the MBEDTLS_PLATFORM_MEMORY PR is queued for merging. There is also a change in internal review for SPIRAM_MALLOC_RESERVE_INTERNAL, to allow this pool to be allocated from multiple non-contiguous regions if needed, to make up the complete size. It also increases the maximum reservation si...

If you call xQueueCreate() or xTaskCreate() or xTaskCreatePinnedToCore(), the memory for the queue contents or the task stack is allocated from heap. If you have external SPI RAM enabled, the tasks have to be allocated from internal memory but the queues can be allocated anywhere. There are also "st...
