* Name: spi_flash_read_encrypted
|
|
*
|
|
* Description:
|
|
*
|
|
* Read data from Encrypted Flash.
|
|
*
|
|
* If flash encryption is enabled, this function will transparently
|
|
* decrypt data as it is read.
|
|
* If flash encryption is not enabled, this function behaves the same as
|
|
* spi_flash_read().
|
|
*
|
|
* See esp_flash_encryption_enabled() for a function to check if flash
|
|
* encryption is enabled.
|
|
*
|
|
* Parameters:
|
|
* addr - source address of the data in Flash.
|
|
* buffer - pointer to the destination buffer
|
|
* size - length of data
|
|
*
|
|
* Returned Values: esp_err_t
|
