Boot. bib and config. bib

The. bib file is used to guide the WinCE compilation system to generate executable binary files. The addresses used are virtual addresses.

BOOT. BIB

Let's take a look at boot. bib. Boot. bib is used to set the virtual memory allocation in the Eboot program.

The RAM region with the starting address 0x8c038000 of EBOOT is used to store the Eboot image (that is, Nboot copies Eboot. nb0 to the RAM region with the starting address 0x8C038000). The size is kb.

 

The RAM region with the starting address 0x8c000000 of PTS is used to store the page table (the address translation table, including g_oalAddressTable). The size is 128KB.

 

 

CONFIG. BIB

Check config. bib again. Config. bib is used to set the virtual memory allocation of the WinCE system.

The RESERVE attribute indicates that the memory of the film is used by BSP, and the system does not need to care about its purpose. RAMIMAGE indicates that it is a piece of memory for storing OS images, while RAM indicates that some pieces of memory are RAM, the system can allocate space and run programs.
