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.
More information about TMS570 BSP can be found at
http://www.rtems.org/wiki/index.php/Tms570
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)

+
+Execution
+
+Currently, a bootloader is not used. For test and debug purposes, TI's
+HalCoGen generated application is used to set up the board and then
+the RTEMS application image is loaded using OpenOCD to internal
+EEC SRAM or external DRAM. The following features are
+not implemented in the BSP:
+
+ + Initial complex CPU and peripheral initialization
+ + Cores Self-test
+
+Setup application code is available there:
+ https://github.com/hornmich/tms570ls3137-hdk-sdram
+
+Howto setup TMDS570LS31HDK?
+
+ o Unpack board.
+ o Verify that demo application runs.
+ o Upload bootloader specified above
+ o write BSP application either to sdram or intram and jump to RTEMS start code
+
+Additional information about the board can be found at
+ http://www.rtems.org/wiki/index.php/Tms570
+
+Additional information about the CPU can be found at
