Part Number: AM5728

Hi,

I'm using AM5728 Linux SDK. Image generated for sdcard and booting fine(similarly for NOR).  I wanted to know NFS, TFTP, Network based Software Upgrade. Could you please let me know various software upgrade procedures Linux SDK supports.

1. Application upgrade: NFS, TFTP, Network

2. Both Uboot, RootFs upgrade(i.e Single Image upgrade)

3. Only Uboot upgrade

Thanks and Regards

    Hello,

    The SDK does not include any specific tools for firmware upgrade and it is considered the role of the system integrator to architect a solution.

    Many of the open source tools like U-Boot have tools to help, and those would generally be supported. The SDK includes basic functionality like NFS, TFTP and in general other network connections that can be used to transfer images. U-Boot and Linux generally provide tools to access partitions and make changes (ROOTFS location in Linux) that can then again be used to manage the process.

    The trickiest part of keeping a golden image during upgrades and validating new images before use, as well as fallback upon failure, are use case specific and left to the individual systems. 

    Commercial Linux providers often provide suites of tools for this process, including cloud connectivity, that can be leveraged.

    I hope this helps you.

    Thanks.
