12.2 Troubleshooting
Q: I’m seeing the following error:
A: You may be using the wrong version of FPT. Please ensure that you are using the
flash tools that were provided in the kit for the target systems.
Q: What does following FPT error message mean?
Error: The host does not have write access to the target flash memory!
A: In order for FPT to read or write to a given region, BIOS/Host must have read/write
permissions to that target region. This access is set in the descriptor. Look closely at all
the addresses defined in the output of FPT /i. If there are any gaps in flash space
defined you cannot perform a full flash write. You have to update region by region.
Refer to 4.3 Region Access Control for more information. You may have to reflash the
descriptor to get the proper access.
Q: What does following FPT error message mean?
Error: Flash program registers are locked! HSFSTS[15] (FLOCKDN).
A: The Flash Configuration Lock-Down (FLCOKDN) bit was set HSFS (hardware
sequencing flash status register). This locks down all the program registers in the ICH.
If your BIOS and descriptor do not set up Hardware Sequencing, you will have to leave
this bit unset in order to use FPT. You may have to upgrade the latest version of FPT as
older versions do not support Hardware Sequencing. Please refer to Hardware
Sequencing Flash Status Register in the Broadwell PCH-LP Family External Design
Specification (EDS) for the location for the HSFS. Try reflashing the SPI device with a
3
rd
Party programmer. If you still see this error message, please contact your BIOS
vendor to ensure that they are not setting this bit.
Q: What does following FPT error message mean?
Error: There is no supported SPI flash device installed.
