6.7.4Alternate Boot Data Structure

The globalData field of the alternate boot data structure points to an area of RAM which was initialized to zeroes by the boot loader. This area of RAM is not cleared by the boot loader after execution of a POST image, or other alternate boot image, is executed. It is intended to provide a user a mechanism to pass POST image results to subsequent boot images.

The boot loader performs no other initialization of the board than that specified prior to the transfer of control to either a POST, USER, or Alternate MOTLoad image. Alternate boot images need to initialize the board to whatever state the image may further require for its execution.

POST images are expected, but not required, to return to the boot loader. Upon return, the boot loader proceeds with the scan for an executable alternate boot image. POST images that return control to the boot loader must ensure that upon return, the state of the board is consistent with the state that the board was in at POST entry. USER images should not return control to the boot loader.

6.7.5Alternate Boot Images and Safe Start

Some later versions of MOTLoad support alternate boot images and a safe start recovery procedure. If safe start is available on the MVME7100, alternate boot images are supported. With alternate boot image support, the boot loader code in the boot block examines the upper 8 MB of the flash bank for alternate boot images. If an image is found, control is passed to the image.

6.7.6Boot Image Firmware Scan

The scan is performed by examining each 1 MB boundary for a defined set of flags that identify the image as being POST, USER, or Alternate MOTLoad. POST is a user-developed Power On Self Test that would perform a set of diagnostics and then return to the boot loader image.

USER would be a boot image, such as the VxWorks bootrom, which would perform board initialization. A bootable VxWorks kernel would also be a USER image. Boot images are not restricted to being 1 MB or less in size; however, they must begin on a 1 MB boundary within the 8 MB of the scanned flash bank. The flash bank structure is shown below:

Address

Usage

 

 

0xFFF00000 to 0xFFFFFFFF

Boot block. Recovery code.

 

 

0xFFE00000 to 0XFFFFFFFF

Backup MOTLoad image

 

 

0xFFD00000 to 0xFFDFFFFF

First possible alternate image

 

 

0xFFC00000 to 0xFFCFFFFF

Second possible alternate image

 

 

....

Alternate boot images

 

 

0xFF899999 to 0xFF8FFFFF

Bottom of flash (flash size varies per product)

 

 

The scan is performed downwards beginning at the location of the first possible alternate image and searches first for POST, then USER, and finally Alternate MOTLoad images. In the case of multiple images of the same type, control is passed to the first image encountered in the scan.
