Download Firmware Intel Joule 1F1

Intel has for its Joule compute module and Joule Developer Kit released a new bios with 1F1 as version number. The Joule compute module is available in two flavors, namely the 550x and 570x. The 550x has a 1.5GHz CPU, 300MHz GPU and 3GB RAM with 8GB emmc flash storage. The 570x has a 1.7GHz CPU with a turbo boost to 2.4GHz, 450MHz GPU with a 600MHz Turbo and 4GB RAM with 16GB emmc flash storage. For more information, we refer you to the data sheet. The list of changes for this release is as follows:

BIOS Version #1F1:

• Fix EEPROM binary won’t validate, ever.
• Fix UART S0ix programming in EEPROM default image.
• Setup Type-C PD negotiations for Type-C PD chargers
• Fix Flash.bat so it will accept a full path for the DNX IFWI binary
• Fixed incorrect CPU frequency value in BIOS setup and MIG OS both
  – This was caused by saving data to the wrong PlatformInfo data structure pointer
• Added a board check to the EEPROM code so it only runs on 570x/550x
• Added code to tell the end-user what version of the EEPROM binary is being used
• Added code to force using the BIOS EEPROM defaults if the GP button is pressed during POST
• Added NVMe into the boot order. New boot order is: USD, eMMC, NVMe, USB, PXE, Shell
• Added VBT into the EEPROM image.
• Add PXE boot and i210 networking stack to Joule BIOS
  • Confirmed that PXE boot works with a UEFI PXE server
  • Set BDS boot priority to uSD, eMMC, USB, Network, Shell

Known Issues:

• The PMIC_PWRGOOD signal contains an ~20uS wide, low going pulse, which may result in unexpected behavior on some custom designed expansion/carrier boards.
