TigerSHARC Processor Booting
TigerSHARC Processor Boot Kernels
Upon completion of the DMA, in all boot modes, the boot-loading process
continues by downloading the boot kernel into the processor
memory. The boot kernel sets up and initializes the processor’s memory.
After initializing the rest of the system, the boot kernel overwrites itself.
� You
can build an .ldr file that includes or does not include a kernel.
To build without a kernel, use the -nokernel command-line
switch or uncheck the Use boot kernel option on the Kernel page
of the Project Options dialog box.
VisualDSP++ includes three distinct kernel programs for each Tiger-
SHARC processor. A boot kernel is loaded at reset into a memory
segment, seg_ldr, which is defined in the ADSP-TSxxx_Loader.ldf file.
The provided files are located in the …\VisualDSP\TS\ldf directory.
