Startup information, including board configuration, is only printed when module esp_log_startup is used. This reduces the amount of information that is printed by default to the console during the startup. The user can enable module esp_log_startup to get the additional startup information.
While deleting multiple sectors in flash, interrupts were disabled over the whole time. Thus, deleting the entire flash led to the triggering of the watchdog timer and thus to a restart. Therefore, the interrupts and the cache are disabled only for the time of deleting a single sector. The same problem occurred for read and write large data sets.
Xtensa newlib version requires pthread_setcancelstate as symbol. Therefore, the module pthread was always used, which in turn requires the module xtimer. The xtimer module, however, uses TIMER_DEV(0). Therefore, tests/timers failed for TIMER_DEV(0).
