TM1300/PNX1300系列DSP（主要用于视频处理）的自动boot程序

1. Please see "TriMedia SDE Book 4, Part C. TriMedia 
   Debugger" for details on debugging TriMedia applications using JTAG.

2. There are two makefiles in this directory -

     makefile.unix - for making flashwrite.mi and flashwrite.eeprom on Sun and HP.

     makefile.win  - for making flashwrite.mi and flashwrite.eeprom on Windows
                     using the MKS Make facility.

     In order to use these makefiles, you must define CC (Host C
     compiler) and TCS (Trimedia toolset installation directory)
     appropriately.

3. The macros SDRAM_BASE and SDRAM_LIMIT can be modified to suit
   any customized TriMedia board design.

   To modify the macros, simply use a text editor and change the
   SDRAM_BASE value to match your board's SDRAM base address and
   the SDRAM_LIMIT value to the value of SDRAM_BASE plus the
   board's SDRAM memory size.

   NOTE 1: SDRAM_LIMIT should contain an address value that is
           just one byte beyond the highest SDRAM address.

           For example, if the SDRAM_BASE is 0xfe000000 and there
           are 4 mega bytes of SDRAM, then SDRAM_LIMIT should be
           set to  0xfe400000.

   NOTE 2: The code in this directory will only work for special DTV 
           stand-alone boards with the AMD Flash Am29F080 part (8 Mb x 4).
           On these boards, the flash memory appears as part of PCI
           space (using PCI glue logic) and can be accessed via simple
           load/store operations.

           Further, it assumes the flash base address at 0xFF400000 
           and the flash sector size to be 0x00040000.


This specific version is used to program the flash via tmdbg. Compile 
a program for the final execution environment (i.e. -host nohost and 
without -g), and download via JTAG with tmdbg.

Note that when the standalone system is powered up with this EEPROM, you 
should wait 20-30 seconds for the flash chip erase to complete, before 
trying to connect via JTAG.  If you did not wait long enough, there's a 
chance that tmdbg will come back with a time-out error.

After the debugger finishes downloading, the program is written into 
flash.  At this point, power off the standalone system - do not reset 
the board, since (with the fwrite eeprom) that will once again erase
the contents of the flash.
