ADSP-219x DSP Booting
The ADSP-219x loader/splitter creates a boot stream, non-boot stream, or
combinational output. The program accepts one executable file (
.DXE
) as
input and generates one file (.
LDR
) as output.
Upon powerup, a ADSP-219x DSP can be booted from the EPROM,
UART, SPI, or Host port. Booting can also be initiated in software after
RESET
. Refer to the Application Note EE-131 and your DSP’s data sheet or
Hardware Reference manual for more information on system configura-
tion, peripherals, registers, and operating modes.
You can run the loader/splitter program from a command-line or from
within the Vi+ IDDE. When working within the Vi+,
specify options via the
Load page of the Project Options dialog box.
!
Option setting on the Load page correspond to switches displayed
on the command line.
