/* TFTP Server OTA Support
|
|
|
|
|
*
|
|
|
|
|
* To use, call ota_tftp_init_server() which will start the TFTP server task
|
|
|
|
|
* and keep it running until a valid image is sent.
|
|
|
|
|
*
|
|
|
|
|
* The server expects to see a valid image sent with filename "filename.bin"
|
|
|
|
|
* and will switch "slots" and reboot if a valid image is received.
|
|
|
|
|
*
|
|
|
|
|
* Note that the server will allow you to flash an "OTA" update that doesn't
|
|
|
|
|
* support OTA itself, and possibly brick the esp requiring serial upload.
|
|
|
|
|
*
|
|
|
|
|
* Example client comment:
|
|
|
|
|
* tftp -m octet ESP_IP -c put firmware/myprogram.bin firmware.bin
|
|
|
|
|
*
|
|
|
|
|
* TFTP protocol implemented as per RFC1350:
|
|
|
|
|
* https://tools.ietf.org/html/rfc1350
|
|
|
|
|
*
|
|
|
|
|
* IMPORTANT: TFTP is not a secure protocol.
|
|
|
|
|
* Only allow TFTP OTA updates on trusted networks.
