Avnet Azure Sphere Starter Kit does not work with the Ethernet examples (new hardware configuration build required) RRS feed

  • Question

  • The Issue


    The current Ethernet implementation requires that the user side load a special hardware imagepackage to the device as documented here.  This package configures the Sphere Hardware and OS to use the ENC28J60 Ethernet device on interface ISU0 with GPIO 5 to expose eth0 on the board.  This hardware configuration works fine with the Seeed board, since these interfaces are available on the header pins and are not being used for other development kit features.


    On the Avnet Starter Kit the desired Ethernet hardware solution is to use a ETH Click board.  The ETH Click board uses the same ENC28J60 device, and using the click sockets makes for a clean solution.  The problem is that the Click Sockets do not use the same interfaces (ISU0 and GPIO 5) as the existing hardware configuration.  The click sockets use ISU1 and GPIO 2.


    Because of these differences the current hardware configuration file, will not work with the Starter Kit.


    The Solution


    The solution to this issue is for have another hardware configuration that uses ISU1 and GPIO 2.  This should be an easy change, but we don’t have access to this source.  Microsoft needs to make these changes and supply the new hardware configuration file.
