TMS320C31 Boot Loader
11-9 Using the TMS320C31 and TMS320C32 Boot Loaders
11.1.4.1 Examples of External TMS320C31 Memory Loads
Table 11–3, Table 11–4, and Table 11–5 show memory images for byte-wide,
16-bit-wide, and 32-bit-wide configured memory (see Figure 4–2 on page 4-6).
These examples assume the following:
An INT0 signal was detected after reset was deasserted (signifying an
external memory load from boot 1).
The source program header resides at memory location 0x1000 and
defines the following:
Boot memory-type EPROMs that require two wait states and SWW = 11
A loader destination address at the beginning of the ’C31 internal
RAM block 1
A single block of memory that is 0x1FF in length
