Support services for programmable logic devices

A non-transitory machine-readable storage medium comprising instructions that upon execution cause a management controller to:

• access a presence value stored in a register to determine a plurality of programmable logic devices associated with the management controller that are present in an electronic device;
• set different multiplexer select values to control a multiplexer in a first programmable logic device to select different programmable logic devices of the plurality of programmable logic devices determined to be present, wherein the first programmable logic device is a member of the plurality of programmable logic devices;
• obtain, based on setting a respective multiplexer select value of the different multiplexer select values, a code image from a second programmable logic device of the plurality of programmable logic devices;
• and
• validate the obtained code image from the second programmable logic device received by the management controller through the multiplexer in the first programmable logic device controlled according to the respective multiplexer select value.

A method comprising:

• populating, at a management controller, stored information comprising a plurality of device identifiers of programmable logic devices present in an electronic device;
• receiving, at the management controller, a code image comprising program code to load into a given programmable logic device of the programmable logic devices, wherein the code image comprises multiplexer information and a device identifier of the given programmable logic device;
• determining, by the management controller, whether the device identifier included in the code image matches a device identifier in the stored information;
• based on determining that the device identifier included in the code image matches the device identifier in the stored information, programming, by the management controller, a multiplexer select value based on the multiplexer information in the code image, the multiplexer select value to control a multiplexer to connect an interface of the management controller to an interface of the given programmable logic device;
• and
• loading, by the management controller, the program code of the code image through the interface of the management controller, the multiplexer controlled by the multiplexer select value, and the interface of the given programmable logic device into the given programmable logic device.
