MOTLoad Firmware

User Images

 

 

zIMAGE_POST

If set, this flag defines the image as being a power-on self-test image. This bit flag is used to indicate that the image is a diagnostic and should be run prior to running either USER or MCG boot images. POST images are expected, but not required, to return to the boot block code upon completion.

zDONT_AUTO_RUN

If set, this flag indicates that the image is not to be selected for automatic execution. A user, through the interactive command facility, may specify the image to be executed.

MOTLoad currently uses an Image Flag value of 0x3, which identifies itself as an Alternate MOTLoad image that executes from RAM. MOTLoad currently does not support execution from flash.

6.7.3User Images

These images are user-developer boot code; for example, a VxWorks bootrom image. Such images may expect the system software state to be as follows upon entry:

zThe MMU is disabled.

zL1 instruction cache has been initialized and is enabled.

zL1 data cache has been initialized (invalidated) and is disabled.

zL2 cache is disabled.

zL3 cache is disabled.

zRAM has been initialized and is mapped starting at CPU address 0.

zIf RAM ECC or parity is supported, RAM has been scrubbed of ECC or parity errors.

zThe active flash bank (boot) is mapped from the upper end of the address space.

zIf specified by COPY_TO_RAM, the image has been copied to RAM at the address specified by ImageRamAddress.

zCPU register R1 (the stack pointer) has been initialized to a value near the end of RAM.

zCPU register R3 is added to the following structure:

typedef struct altBootData {

unsigned int ramSize;/* board's RAM size in MB */ void flashPtr;/* ptr to this image in flash */ char boardType[16];/* name string, eg MVME7100 */ void globalData;/* 16K, zeroed, user defined */ unsigned int reserved[12];

} altBootData_t;
