And then I'm going to run either a-app or b-app, and in the APP, what configuration do I want to do?
Hope experts can provide support, it is best to have a source demo, thank you.

CC1312R has serial bootloader for firmware update from UART. You can to refer to chapter 10 Bootloader in CC13x2, CC26x2 SimpleLink™ Wireless MCU Technical Reference Manual and Linux® Serial Bootloader Example Application.

MCU serial port needs to communicate with 4G module all the time. If you use hardware BOOT, the 4G network will be disconnected. I had to keep the server connected to the 4G module and download the new application into flash. Hardware BOOT does not support this.So, I want to use software to configure and update the application code.But I don't know how to code software BOOT( the boot program).

这个方案是我需要的,不知道有没有demo,有的话请发送到我的邮箱1531739026@qq.com谢谢

我详细看了一下,这个是片上的boot。我要把服务器里面放的应用程序,通过4G模块下载到MCU的flash。如果要是用硬件boot,这样会导致4G模块掉线,没有办法执行啊。有没有一种办法,像我们平时往flash中存放数据一样,把代码存储进去,然后复位MCU,通过引导程序,来执行新的应用代码,然后擦除旧的应用程序。我希望是通过这种模式实现固件的更新。

这樣的引导程序要自己去作

有没有这样的例程,思路是有,但是不知道如何去实现。

可以參考BIM例程

BIM例程在SDK里面吗?我没有找到这个例程。我安装的simplelink_cc13x2_26x2_sdk_3_20_00_68
