Description
Board
ESP32-C3 / ESP32-S3
Device Description
Any ESP32-C3 or -S3 using HWCDC
Hardware Configuration
Any ESP32-C3 or -S3 board using HWCDC
Version
v2.0.9
IDE Name
PlatformIO
Operating System
Windows 11
Flash frequency
40MHz
PSRAM enabled
yes
Upload speed
115200
Description
HWCDC::end() does not reset the semaphore.
So after a call to end()
and a new call to begin()
the tx_lock
semaphore is invalid.
Thus trying to write something to that port again will cause a crash.
arduino-esp32/cores/esp32/HWCDC.cpp
Lines 190 to 205 in 3ec5f4e
void HWCDC::end() | |
{ | |
//Disable tx/rx interrupt. | |
usb_serial_jtag_ll_disable_intr_mask(USB_SERIAL_JTAG_LL_INTR_MASK); | |
esp_intr_free(intr_handle); | |
intr_handle = NULL; | |
if(tx_lock != NULL) { | |
vSemaphoreDelete(tx_lock); | |
} | |
setRxBufferSize(0); | |
setTxBufferSize(0); | |
if (arduino_hw_cdc_event_loop_handle) { | |
esp_event_loop_delete(arduino_hw_cdc_event_loop_handle); | |
