Hex Conversion Utility Examples
C.5 Example 4: Generating a Boot Table for LP Core Devices
Example 4 shows how to use the linker and the hex conversion utility to build
a boot load table for the ’C54xLP devices. For the ’C54xLP devices, you can
specify multiple sections. It is not necessary, therefore, to group sections at link
time as with the non-LP devices. The assembly code used in this section is
shown in Example C–1 on page C-2.
Note:
This example is for ’C54xLP devices only.
For non-LP ’C54x devices, see Section C.4,
Example 3: Generating a Boot
Table, on page C-10.
Example C–13. C Code for a ’C54xLP
int array[]={1,2,3,4};
main()
{
array[0] = 5;
}
Figure C–4 shows the EPROM memory system for which the output file will be
generated. In this application, the single ’C54xLP device is booted from a 128K
8-bit EPROM. The requirements of the system are that the boot table must
reside at EPROM memory address 0.
