If not set defaultthe bootloader will permanently disable UART bootloader decryption access on first boot.

Path to a public key file used to verify signed images. So do not enable DFS if bluetooth modem sleep is in use. Once the specific mode is selected the UART driver will handle behavior of external peripheral according to mode.

More stack frames uses more memory in the heap trace buffer and slows down allocationbut can provide useful information.

These operations are used by RSA. This can catch hardware problems with SPI flash, or flash which was not erased before configurration. Configure the panic handlers action here. The positions of the detected pattern are saved in a queue, This function do nothing to the queue. If set to NULL, driver will not use an event queue. Other indexes can be used for any desired purpose. Size of the buffer for events in bytes.

The partition table determines where apps, data and other resources are expected to be found. The two main uses of renegotiation are 1 refresh keys on long-lived connections and 2 client authentication after the initial handshake.

If this option is not enabled, PHY init data will be embedded into the application binary. The idle task has its own stack, sized in bytes. Timeout period configuration for the Task Watchdog Timer in seconds. They must be signed manually using espsecure. Longer messages are dropped.

FIFO space threshold or transmission timeout reached – the interrupts on TX or Rx FIFO buffer being filled with specific number of characters or on a timeout of sending or receiving data. It sets up an intermediate ring buffer and exits after copying the data to this buffer.

If only RTC timer is znd, timekeeping will continue in deep sleep, but time will be measured at 6.

This can be useful when debugging hardware SPI flash problems. Data collisions are usually associated with the presence of other active devices on the bus or due to bus freertos reference manual – api functions and configuration options. Pointer to accept value of UART stop bits. This option reserves a pool specifically for requests like that; confighration memory in this pool is not given out when a normal malloc is called.

Disabled entirely not recommended for most configurations. Set this to 0 to referdnce this feature. Compared to the Safety mode, this operation is faster, but if power will freetos lost when erase sector operation is in progress, then the data from complete flash device sector will be lost. In Performance mode a data will be stored to the RAM and then stored back to the flash.

When this option is enabled, these fuctions will throw optikns assert. You can generate a new signing key by running the following command: Only enable these options if you are very sure. If your certificates are all in the simpler DER format, disabling this option will save some code size.

The maximum value of threshold is Below is the example of using this function:. If power management support is enabled, FreeRTOS will be able to put the system into light sleep mode when no tasks need to run for a number of ticks. Larger number of buffers increases throughput.

Note that run time stats are only valid until the clock source overflows.

Log output will state changes which would be applied, but they will not be. Most of time we should NOT change the default value unless special reason, e. This output can be further suppressed by bootstrapping GPIO13 pin to low logic level.

If this option is enabled, RTC timer will be used as a reference to compensate for the drift. The same macro should be entered if certain pin will not be used.
