This scenario is for single chip devices of the Internet of things to upgrade directly online or indirectly access to the public network through the gateway Wi Fi / BT / USB / ZigBee.
UC SDK is integrated in the application layer, which is mainly responsible for the control of the upgrade process, providing networking, reporting, downloading, verification, storage and other interfaces to the user app call;
UA SDK is integrated in the boot layer, which is mainly responsible for restoring differential packets locally and writing them through bootloader
For Linux / Android / RTOS / QNX operating system, UA SDK needs independent recovery partition
Direct networking - bike sharing, smart watch, car machine, GPS tracker, dash cam;
Indirect networking - Smart bracelet, beacon device, ZigBee smart home, rearview mirror;
This scenario is oriented to upgrade the device system composed of multiple MCU
The main chip of the device is connected with other MCU through internal bus such as uart/spi/can
Mixed upgrade solution of multi system in device (Linux / Android / RTOS / QNX operating system)
UC SDK is integrated in the application layer, which is mainly responsible for the control of the upgrade process, providing networking, reporting, downloading, verification, storage and other interfaces to the user app call;
UA SDK is integrated in the boot layer, which is mainly responsible for restoring differential packets locally and writing them through bootloader
For linux/android/rtos/qnx operating system, UA SDK needs independent recovery partition
Upgrade of independent MCU in vehicle engine system; The robot system is connected to the Internet through the communication module, and the main CPU is connected to the independent MCU and the upgrade of different operating systems.
This scenario is for single chip devices of the Internet of things to upgrade directly online or indirectly access to the public network through Wi Fi / BT / USB / ZigBee.
