Hello Team,
For each power cycle Quark BIOS is consuming 872 bytes of runtime variable space from Variable store on FLASH and
it is not releasing unused variable space memory.
After 53 power cycles the remaining run time variable space(0x28 Bytes) is below the threshold value (0x400 bytes) and BIOS is trying to reclaim the unused variable space from the below file.
edk2/MdeModulePkg/Universal/Variable/RuntimeDxe/Variable.c +3627
VOID
ReclaimForOS()
{
Reclaim() //Line 3627
}
But failed with below error:
"F2 key to enter Boot Manager Menu.

I debugged this Issue:
As part of reclaim operation BIOS is erasing the variable space on flash and trying to write again without unused variables to flash but SPI protection is enabled and SPI write failed.
My current Fix for the above problem:
I disabled the SPI protection in the below file:
QuarkPlatformPkg/Library/PlatformHelperLib/PlatformHelperLib.c +81
EFI_STATUS
WriteFirstFreeSpiProtect()
{
RegVal |= B_QNC_RCRB_SPIPBRn_WPE; //Disabled this line;
}
Is this the correct solution for the above issue?
Anybody observed this issue?
