    fw_update
    example
Changed:
  • Use
    VERSION
    file to specify application version in

Known Issues:
  • [Zephyr only] Espressif devices have a regression in Zephyr 3.7 that frequently causes crashes during flash operations. We recommend remaining on Zephyr 3.6 and Golioth Firmware SDK [0.14.0] until the issue is is resolved. For more information see https://github.com/zephyrproject-rtos/zephyr/issues/77952
  • [Zephyr only] Boards utilizing the ESP AT WiFi driver, such as the nRF52840 DK + ESP32, frequently fail to complete DTLS handshakes when using certificate authentication due to an issue with DTLS fragment handling when operating in passive mode, which is required for DNS resolution in Zephyr 3.7. For more information see https://github.com/zephyrproject-rtos/zephyr/issues/77993
Workarounds:
  • The MIMXRT1024-EVK received a new upstream Ethernet driver that was found to have sporadic "Link Down/Up" events that cause a loss of connectivity when downloading binaries during OTA Firmware Update. All Zephyr examples in this release include an overlay file for this board that reverts to the old driver.
