This workaround makes sure that all ringbuf functions that may be called from an ISR are placed in IRAM. See https://github.com/espressif/esp-idf/issues/13378 Note that this means that all esp32-og builds get non-ISR ringbuf functions placed in flash now, whereas previously it was just the spiram variant. This might be a good thing (e.g. free up some IRAM for native/viper). Fixes issue #14005. This work was funded through GitHub Sponsors. Signed-off-by: Jim Mussared <jim.mussared@gmail.com>
