Config.bib Customization

  • Article

The Config.bib file is the first place to declare how much memory will be made available to the kernel. A single entry is required and should indicate the default amount of RAM that is possible for the device.

The following code example shows a sample Config.bib file.

Section Name   Start RAM Address   Number of Bytes   Section Type
RAM            80b00000            00500000          RAM

Only one contiguous memory section of RAM can be reported in the Config.bib file. All other memory extensions must be handled through MainMemoryEndAddress, OEMGetExtensionDRAM, or pNKEnumExtensionDRAM customization. The start address of RAM and the number of bytes determine the value of ulRAMEnd (start + number of bytes) where ulRAMEnd is a parameter of the table of content specified in Romldr.h. ulRAMEnd is calculated and set in the OS image every time an OS image is created.
