BSP for TMS570LS31x Hercules Development Kit from TI (TMS570LS3137)

Included variants:

tms570ls3137_hdk_intram - place code and data into internal SRAM
tms570ls3137_hdk_sdram - place code into external SDRAM and data to SRAM
tms570ls3137_hdk - variant prepared for stand-alone RTEMS aplication

stored and running directly from flash. Not working yet.

Chip initialization code not included in BSP.
External startup generated by TI's HalCoGen? was used for
testing and debugging.

Patch version 2

  • most of the formatting suggestion applied.
  • BSP converted to use clock shell
  • console driver "set attributes" tested. Baudrate change working

Patch version 3

  • more formatting changes.
  • removed leftover defines and test functions

Todo:

refactor header files (name register fields)

  • Property mode set to 100644

42Execution
43
44Currently, a bootloader is not used. For test and debug purposes, TI's
45HalCoGen generated application is used to set up the board and then
46the RTEMS application image is loaded using OpenOCD to internal
47EEC SRAM or external DRAM. The following features are
48not implemented in the BSP:
49
50 + Initial complex CPU and peripheral initialization
51 + Cores Self-test
52
53Setup application code is available there:
54          https://github.com/hornmich/tms570ls3137-hdk-sdram
55
56Howto setup TMDS570LS31HDK?
57
58        o Unpack board.
59        o Verify that demo application runs.
60  o Upload bootloader specified above
61  o write BSP application either to sdram or intram and jump to RTEMS start code
