In addition, the operation of other tools (such as the C/C++ compiler) is influenced by whether the loader utility is used. If you do not specify a boot kernel file via the Load page of the Project Options dialog box in VisualDSP++ (or via the -l kernelfile command-line switch), the loader utility places a default boot kernel in the loader output file (see “ADSP-21161 Processor Boot Kernels” on page 4-16) based on the specified boot mode. Rebuilding a Boot Kernel File If you modify the boot kernel source (.asm) file by inserting correct values for your system, you must rebuild the boot kernel (.dxe) before generating the boot-loadable (.ldr) file. The boot kernel source file contains default values for the SYSCON register. The WAIT, SDCTL, and SDRDIV initialization code is in the boot kernel file comments. 4-18 VisualDSP++ 4.5 Loader and Utilities Manual
To Modify a Boot Kernel Source File Loader for ADSP-21161 SHARC Processors 1. Copy the applicable boot kernel source file (161_link.asm, 161_host.asm, 161_prom.asm, or 161_spi.asm). 2. Apply the appropriate initializations of the SYSCON and WAIT registers. After modifying the boot kernel source file, rebuild the boot kernel (.dxe) file. Do this from the VisualDSP++ IDDE (refer to VisualDSP++ online Help for details), or rebuild the boot kernel file from the command line. Rebuilding a Boot Kernel Using Command Lines Rebuild a boot kernel using command lines as follows. EPROM Boot. The default boot kernel source file for EPROM booting is 161_prom.asm. After copying the default file to my_prom.asm and modifying it to suit your system, use the following command lines to rebuild the boot kernel. easm21k -proc ADSP-21161 my_prom.asm linker -T 161_ldr.ldf my_prom.doj Host Boot. The default boot kernel source file for host booting is 161_host.asm. After copying the default file to my_host.asm and modifying it to suit your system, use the following command lines to rebuild the boot kernel. easm21k -proc ADSP-21161 my_host.asm linker -T 161_ldr.ldf my_host.doj VisualDSP++ 4.5 Loader and Utilities Manual 4-19
