A root region is a region with the same load and execution address. The initial entry point of the image must be in a root region. If the initial entry point is not in a root region, the link fails and the linker gives an error message.
Example 12. Root region with the same load and execution address
LR_1 0x040000 ; load region starts at 0x40000
{ ; start of execution region descriptions
ER_RO 0x040000 ; load address = execution address
{
* (+RO) ; all RO sections (must include section with
; initial entry point)
}
... ; rest of scatter-loading description
}
