| | | | | | | | | | | | | | | | | | | | HalCoGen generated files. The configuration is specific for TMS570LS3137 based HDK. Pins configuration can be easily changed in rtems/c/src/lib/libbsp/arm/tms570/hwinit/init_pinmux.c file. The list tms570_selftest_par_list in the file rtems/c/src/lib/libbsp/arm/tms570/hwinit/bspstarthooks-hwinit.c specifies peripherals which health status is examined by parity self-test at BSP start-up. It can be easily modified for other TMS570 family members variants same as the selection of other tests in bspstarthooks-hwinit.c.
* arm/tms570: define base addresses of all TMS570LS3137 SPI interfaces.Pavel Pisa2016-10-021-1/+5
| | | | | | | | Generated header file ti_herc/reg_spi.h contains complete registers and fields set for Ti MibSPI peripheral. Care has to be taken that only TMS570_SPI1, TMS570_SPI3 and TMS570_SPI5 are of this complete multibuffer type. TMS570_SPI2 and TMS570_SPI4 have substantial part of registers removed but else they are compatible.
* bsp/tms570: ensure that change of SCI baudrate is not applied in the middle ↵Pavel Pisa2016-10-021-2/+23
| | | | | | | | | | | | | | | | | | | of character Tx. The rtems_monitor_task() setups/updates termios attributes of the opened TTY and if there is ongoing some other output it leads to the stuck. It would be better to use some termios API function which would call drainOutput() in rtems/cpukit/libcsupport/src/termios.c. But functionality is not accessible outside of core termios implementation. The loop waiting for last character to be sent has to be there anyway because hardware does not provide Tx machine/shift register empty interrupt. Closes #2794

Variant tms570ls3137_hdk_with_loader skips 256kB at start of Flash to allow use with application loader. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* bsp/tms570: use POM only when application image does not start at address 0.Pavel Pisa2015-11-187-14/+159
| | | | | | | | | | | | | | | | | | | | | Parameters overlay module is initialized and cleared first. It is used later to replace exception target vectors only if that is required. The application loader code with CPU and SDRAM setup code has to provide well defined pattern of instructions at addresses 0x00000000 and 0x0000001f, because only data read accesses can be processed reliably by POM. The expected instruction pattern can be seen in the next example https://github.com/hornmich/tms570ls3137-hdk-sdram/blob/master/SDRAM_SCI_configuration/source/sys_intvecs.asm Comments with detailed description of code, background and reasons for selected approach have been included in TMS570 bsp startup code.

* ARM: Add BSP_START_NEEDS_REGISTER_INITIALIZATIONMartin Galvan2015-02-272-0/+6
| | | | | | | | | | | | | This patch adds the macro BSP_START_NEEDS_REGISTER_INITIALIZATION and three hooks for BSP-specific register init code to arm/shared/start.S. Said hooks are bsp_start_init_registers_core (intended for initializing the ARM core registers), bsp_start_init_registers_banked_fiq (for the FIQ mode banked registers) and bsp_start_init_registers_vfp (for the FPU registers). BSP_START_NEEDS_REGISTER_INITIALIZATION would be defined in a BSP's configure.ac (so that it appears in its bspopts.h). This patch also adds the register init code required by the TMS570. We've tested it with the tms570ls3137_hdk.cfg config and it works fine.
* arm/tms570: sci context has to be writable because it holds state variable.Pavel Pisa2015-02-042-4/+4
| | | | | | | | | | | | | | The structure tms570_sci_context holds state variable tx_chars_in_hw which holds if and how many characters (in the optional FIFO support for some Ti SCIs) are submitted into hardware. When field is not writable then code breaks when RTEMS is build for Flash area. The problem found and analyzed by Martin Galvan from tallertechnologies.

* Use correct prototype of benchmark_timer_read()Joel Sherrill2014-09-161-2/+1
| | | | | | | | | | | | | | This change starts with removing the effectively empty file timerdrv.h. The prototypes for benchmark_timer_XXX() were in btimer.h which was not universally used. Thus every use of timerdrv.h had to be changed to btimer.h. Then the prototypes for benchmark_timer_read() had to be adjusted to return benchmark_timer_t rather than int or uint32_t. I took this opportunity to also correct the file headers to separate the copyright from the file description comments which is needed to ensure the copyright isn't propagated into Doxygen output.

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)
