Linux/OMAP-L138: How much capacity LCDK can support on SATA?

Part Number:OMAP-L138

Tool/software: Linux

HI,

When I use the SD which is the part of LCDK (Official provided)，I find out that the LCDK can Identify 1000GB.

But when I use the " ti-processor-sdk-linux-omapl138-lcdk-04.00.00.04-Linux-x86-Install.bin" ,I can not use 500GB.

I read the datasheet,I know the OMAP-L138 have 32bit addressing.

If the sector is 512byte ,now the LCDK can support 2TB

and the most HDD have 4096byte sectors.

so,I am confusing that how can I make the kernel and modules to support much more capacity.

thanks.
