Previously, reset over USB CDC was done by calling esp_restart from an interrupt handler. This works only until some restart hook function is registered using esp_register_shutdown_handler, and the hook function tries to do something that isn’t allowed in an interrupt handler. One such case is with Wi-Fi. When Wi-Fi driver is installed, it registers esp_wifi_stop as a shutdown handler function. However esp_wifi_stop cannot be called from an ISR, and hence we shouldn’t call esp_restart from an ISR either. This commit modifies USB CDC driver to call esp_restart by posting it to esp_timer task. Closes https://github.com/espressif/esp-idf/issues/7404

# This file documents the expected order of execution of ESP_SYSTEM_INIT_FN functions.
|
|
#
|
|
# When adding new ESP_SYSTEM_INIT_FN functions or changing init priorities of existing functions,
|
|
# keep this file up to date. This is checked in CI.
|
|
# When adding new functions or changing the priorities, please read the comments and see if
|
|
# they need to be updated to be consistent with the changes you are making.
|
|
#
|
|
# Entries are ordered by the order of execution (i.e. from low priority values to high ones).
|
|
# Each line has the following format:
|
|
# prio: function_name in path/to/source_file on affinity_expression
|
|
# Where:
|
|
# prio: priority value (higher value means function is executed later)
|
|
# affinity_expression: bit map of cores the function is executed on
