* Add build support for targeting multiple STM32 series.Marti Bolivar2012-04-111-0/+0
| | | | | | | | | | | | | | | | | | | Add an MCU_SERIES variable to each of the files under support/make/board-includes, which declares the series as "stm32f1" in each case. Use this in target-config.mk when determining LD_SERIES_PATH (with a hack since we only support performance line) and LIBMAPLE_MODULE_SERIES. We must move support/ld/stm32/series/f1 to .../series/stm32f1 as a side-effect. Adding support for other series (e.g. "stm32f2") should now be a matter of filling in the contents of libmaple/<series>/ and support/ld/stm32/<series>/ appropriately (along with moving the rest of the nonportable code out of the libmaple core and into the STM32F1 series submodule).

* Great renaming: use "series" instead of "family".Marti Bolivar2012-04-111-0/+0
| | | | | | | | | | | | | | | | | This is for greater consistency with the ST application notes, which refer to migrating "across" series (e.g. F1 to F2), but compatibility "within" a family (e.g. F1). So: - Move libmaple/stm32x/include/family to .../include/series/ and fix up includes appropriately. - Refer to "family" headers as "series" headers in comments. - Make similar "find and replace"-style changes to build system variable names and comments. - Move support/ld/stm32/family to .../stm32/series.

* Tweak family-specific linker file layout.Marti Bolivar2012-04-111-0/+0
| | | | | | | | | | | | | Move support/ld/stm32/f1/performance/vector_symbols.inc to support/ld/stm32/family/f1/performance/vector_symbols.inc Creating directory "family" under support/ld/stm32 will allow parallel directories (e.g. support/ld/stm32/mcu) to exist, which allows an eventual linker script cleanup to go much more smoothly.

* Fix linking and C runtime initialization on F1.Marti Bolivar2012-04-111-30/+23
| | | | | | | | | | | | Reorder the .data and .rodata sections in common.inc. This seems necessary to get the linker to place the data ROM disk and the pointer to it in the right places. Switch from long long to int in start_c.c. I have no idea why this helps, but it does. F1 will crash if you don't do this. It will probably slow things down unnecessarily on F2, but I don't care.

* Remove "CS3" prefix from libmaple symbol names.Marti Bolivar2012-04-112-9/+9
| | | | | | | | | | | | | | | | | | | We're no longer even marginally compatible with CS3, so it's inappropriate to use that prefix in our names. Rename: __cs3_stm32_vector_table -> __stm32_vector_table. __cs3_stack -> __msp_init __cs3_reset -> __exc_reset __cs3_start_c -> start_c Also add an MIT license header and assert LeafLabs copyright over wirish/start.S and wirish/start_c.c. These files are modified from the original CodeSourcery versions, which were distributed under a license that permits modifications to be distributed under a different copyright and licensing terms than the originals.

* Remove CS3-style initialization.Marti Bolivar2012-04-1120-528/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove libcs3-related bits from support/ld. Break them out into libmaple proper and Wirish as appropriate: vector table definition and ISR declarations go into libmaple proper, and startup code goes into Wirish. Vector table symbols are included into common.inc from an STM32 family-specific directory under support/ld/stm32. This is a combination of 5 commits. Individual commit messages follow: libcs3_stm32_src: Don't depend on cs3.h. So we can use the existing toolchain. Move ISR decls/vector table into libmaple proper. This allows us to configure the vector table on a per-family basis. - Move support/ld/libcs3_stm32_src/stm32_isrs.S stm32_vector_table.S to libmaple/stm32f1/isrs_performance.S vector_table_performance.S, respectively. The directory libmaple/stm32f1/ is intended to hold all STM32F1-specific code within libmaple. Obviously, there's a lot of work to do before this becomes true. - support/ld/libcs3_stm32_src/Makefile: Don't try to compile stm32_isrs.S and stm32_vector_table.S anymore. - Add libmaple/stm32f1/rules.mk to include these new files in the standard libmaple build. - support/make/target-config.mk: Add LIBMAPLE_MODULE_FAMILY, which selects a directory to use as a family-specific libmaple submodule. - Makefile: Add LIBMAPLE_MODULE_FAMILY to LIBMAPLE_MODULES. Remove support/ld/libcs3_stm32_src and derived object files. From support/ld/libcs3_stm32_src, move start.S and start_c.c into Wirish. Modify wirish/rules.mk accordingly. Delete support/ld/libcs3_stm32_*_density.a. These are no longer necessary, as the relevant objects are included in the standard Wirish build. Remove the GROUP statements from the board linker scripts accordingly. Remove SEARCH_DIR(.) from common.inc; it's no longer necessary. Also fix up some comments that are now out of date. wirish/start_c.c: Don't use CS3-style memory initialization. Switch memory initialization to a simpler style of initializing .data if necessary, then zeroing .bss. Initializing .data is only necessary during Flash builds, since during RAM builds, LOADADDR(.data) == ADDR(.data). This makes libmaple completely incompatible with the CS3 startup sequence. Subsequent commits will clean up the namespace to reflect that fact. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* Make vector table symbols family-specific during linking.Marti Bolivar2011-11-152-4/+7
| | | | | | | | | | | | | | | | | - support/make/target-config.mk: add LD_FAMILY_PATH, the directory to search for STM32 family-specific link configuration files. For now, this is just a stub which points to support/ld/stm32/f1/performance, since that's all we currently support. We can add the logic to support different STM32 families here later. - Makefile: Pass -L $(LD_FAMILY_PATH) to linker. - Rename support/ld/names.inc to support/ld/stm32/f1/performance/vector_symbols.inc. - common.inc: INCLUDE vector_symbols.inc instead of names.inc.

* Add support for the Olimex STM32 H103 board.David Kiliani2011-09-271-0/+1

* [support/ld] Unify linker scripts.Marti Bolivar2011-09-1315-248/+89
| | | | | | | | | | | | | | | | Add new common.inc, which is common_rom.inc with some DEFINED(_FLASH_BUILD) usages thrown in to allow for RAM builds. It also uses a new REGION_RODATA region alias for read-only data. Move section .USER_FLASH to REGION_RODATA. This means it lives in RAM under RAM builds. Although this might be surprising, not doing so would make RAM builds useless. Modify the individual board linker scripts to properly set REGION_RODATA and _FLASH_BUILD before calling out to common.inc. Delete common_rom.inc, common_ram.inc, common_header.inc, in favor of common.inc. This should fix RAM builds on all boards.
* [support/ld] Put Maple Native's heap on external SRAM chip.Marti Bolivar2011-09-123-0/+12
| | | | | | Specify _lm_heap_start and _lm_heap_end in Maple Native's linker scripts to point respectively to beginning and end of FSMC-mapped external SRAM chip addresses.
* [support/ld] Add linker support for reconfigurable heap.Marti Bolivar2011-09-122-2/+16
| | | | | | | | | | | | | | | - common_header.inc: Declare EXTERN symbols _lm_heap_start and _lm_heap_end. - common_rom.inc: Check for _lm_heap_start and _lm_heap_end. If they are defined, preserve their values. Otherwise, _lm_heap_start is starts after .bss, and _lm_heap_end is the end of SRAM. This allows existing linker scripts to continue using the old heap scheme, but allows for customizability elsewhere. - syscalls.c: Respect the addresses of _lm_heap_start and _lm_heap_end as the boundaries of the heap in _sbrk().

* [support/ld] Factor out header from common_rom.inc, common_ram.inc.Marti Bolivar2011-09-073-73/+48
| | | | | | | The linker scripts share an initial section. Factor this out into a new file common_header.inc, and have the main linker scripts include this file. Apart from eliminating a redundancy, this will make it easier to add new linker scripts in the future.
* DMA: Fix non-working DMA interrupts.Marti Bolivar2011-06-201-7/+7
| | | | | | | | | | | | | | | | | | | | | | libmaple/dma.c defines DMA interrupts __irq_dma_channel[1-7], consistent with what is specified by support/ld/names.inc. However, names.inc is inconsistent with what support/ld/libcs3_stm32_src/ expects. Specifically, it contradicts the files - support/ld/libcs3_stm32_src/stm32_isrs.S - support/ld/libcs3_stm32_src/stm32_vector_table.S Which use the names __irq_dma1_channel[1-7]. Change names.inc and dma.c to use the correct IRQ names. The original names.inc/libcs3_stm32_src inconsistency was introduced in 43d6921658cd29b8022af4424d340a90fbcb9a7f, but dma.c had the correct names until ec3cf2903f4b03bc1dae5e159495c9e5ef0938ca, where they were renamed for consistency with names.inc. At that point, DMA interrupts stopped working. (This was documented in the commit message). Thanks to forum user robodude666 for tracking this down.
