Firmware updates are typically delivered as a ZIP archive containing only the firmware images. The con-

tent of the archive with the directory structure must be copied on a data storage device with FAT par-

tition. If the command kBoardConfig AutoUpdate has been enabled, the images are automatically

detected during boot-up and an update of the uEFI BIOS or the IPMI firmware is carried out.

The AM4024(E) has two SPI boot flashes programmed with the uEFI BIOS, a standard SPI boot flash and

a recovery SPI boot flash. The basic idea behind that is to always have at least one working uEFI BIOS

flash available regardless if there have been any flashing errors or not.

The standard SPI boot flash can be updated with the latest uEFI BIOS from the ZIP archive using the

kUpdate -u or the kFlash -p uEFI Shell command. When using the kUpdate command, the directory

structure of ZIP archive must not be altered. The update status is indicated in the log file located in the

directory where the firmware images are stored.
