11.1.4 TMS320C31 Boot Data Stream Structure

Table 11–2 shows the data stream structure. The data stream is composed of
a header of 1 (serial-port load) or 2 (memory load) words and one or more blocks
of source data. The boot loader uses this header to determine the physical
memory width where the source program resides (memory load) and to configure
the primary bus interface before source program boot load. The blocks of
source data have two entries in addition to the raw data. The first entry in this
block indicates the size of the block. The second entry in this block indicates the
memory address where the boot loader copies this source block. Words 5
through

n of the shaded entries in Table 11–2 contain the source data for the first

block.
