Improper fixup problem in library when using compact model

Amit Alon

Hello,

my code passes compilation fine when using small or large models. however when changing the project to use compact model, I get the following errors, (which seem like library bugs) (???):

    I use the DP8051 od DCD (Digital Core Design).
    I think that a new startup.a51 should be created for them: they use DPP (which is Data Page Pointer) mechanism. the DPP is located according to their include file at address 0x93, while PORT2 is a separate entity that is not related to the memory Page Selection.

    Should I change the PPAGE_SFR's value from 0A0 to 093 ?

    Should I enable it at all (after reset the deafult DPP will allways be 0, which suits our design, and to my understanding the startup code will only set it to this value and do nothing else, since I don't want to spend time for the pdata memory initilization to 0 (I didn't change the settings of PDATALEN, and left it to be zero) ?

    Additionaly, I want to explain that the value of DPP changes along the SW flow frequently.

    Amit.
