From a39a5af1cbc6f729f5577c52589538533de7c311 Mon Sep 17 00:00:00 2001 From: Marti Bolivar Date: Tue, 29 Nov 2011 02:48:58 -0500 Subject: build system: Add board include files for target-config.mk. target-config.mk is getting a little long with all the boards in it. Break out the board-specific bits into individual files under support/make/board-includes. This has the added benefit that adding a new board requires less dirtying of the working tree, which is nice for jumping around branches with an experimental board.

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// and support/ld/stm32// appropriately (along with moving the rest of the nonportable code out of the libmaple core and into the STM32F1 series submodule).

Add STM32_HAVE_USB feature test macro requirement for . This will let us test if we've got a USB peripheral. wirish/stm32f1/boards_setup.cpp is set up to use this when turning on USB CDC ACM support at init() time. Rework the STM32F1 to make it easier to support the various lines that subdivide that series. We don't really support anything besides performance line yet, but there's been enough enthusiasm for value and connectivity line support in the past that these hooks seem worth adding. This means adding an STM32_F1_LINE macro and STM32_F1_LINE_[PERFORMANCE,VALUE,ACCESS,CONNECTIVITY] macros for values that STM32_F1_LINE can take, and generalizing the rest of the file to begin taking this into account. Some TODOs remain, but filling these in is the responsibility of future libmaple porting efforts. One pleasant consequence of the F1 stm32.h rework is that the build system no longer has to tell us what density of F103 we're building for, so remove that from the relevant support/make/board-includes/ files. Add some tweaks to and the STM32F2 stm32.h header to make sure this went through properly, and continues to go through properly in the future. --- libmaple/include/libmaple/stm32.h | 12 +++ libmaple/stm32f1/include/series/stm32.h | 100 ++++++++++++++++------- libmaple/stm32f2/include/series/stm32.h | 1 + support/make/board-includes/maple.mk | 2 - support/make/board-includes/maple_RET6.mk | 2 - support/make/board-includes/maple_mini.mk | 2 - support/make/board-includes/maple_native.mk | 2 - support/make/board-includes/olimex_stm32_h103.mk | 2 - wirish/stm32f1/boards_setup.cpp | 2 + 9 files changed, 84 insertions(+), 41 deletions(-) (limited to 'support/make/board-includes') diff --git a/libmaple/include/libmaple/stm32.h b/libmaple/include/libmaple/stm32.h index d6f3304..d53af3a 100644 --- a/libmaple/include/libmaple/stm32.h +++ b/libmaple/include/libmaple/stm32.h @@ -58,9 +58,21 @@ extern "C" { * * - STM32_HAVE_FSMC: 1 if the MCU has the FSMC peripheral, and 0 * otherwise. + * + * - STM32_HAVE_USB: 1 if the MCU has a USB peripheral, and 0 + * otherwise. */ #include +/* Ensure the series header isn't broken. */ +#if (!defined(STM32_PCLK1) || !defined(STM32_PCLK2) || \ + !defined(STM32_MCU_SERIES) || !defined(STM32_NR_INTERRUPTS) || \ + !defined(STM32_NR_GPIO_PORTS) || !defined(STM32_DELAY_US_MULT) || \ + !defined(STM32_SRAM_END) || !defined(STM32_HAVE_FSMC) || \ + !defined(STM32_HAVE_USB)) +#error "Bad STM32F1 configuration.

The good news is that and did turn out generic enough in what they specify to go on unchanged. However, we can't just go on assuming that there's USB just because we're on an F1. Now that there's value line in the tree, we need to be more careful (value line F1s don't have USB peripherals). To that end, make all the F1 board-includes/*.mk files specify what line their MCU is with an MCU_F1_LINE variable. Use that to hack libmaple/usb/rules.mk so we only try to build the USB module under appropriate circumstances. While we're at it, add a vector_symbols.inc for value line MCUs under support/ld/. We need this to get the target-config.mk modifications implied by the addition of MCU_F1_LINE. We'll fix up some other performance-line-isms under libmaple/stm32f1 in a separate commit. Also in libmaple/usb/: - Move everything into a new stm32f1 directory. Due to aforementioned rules.mk hacks, there is no immediate need for an stm32f2 directory (USB support doesn't exist there). - Update the README for style and content.

Having separate linker scripts for all the boards is a bad idea. Most boards really only need to specify MEMORY and the appropriate REGION_ALIASES() so that support/ld/common.inc can do its work. Not having infrastructure for this leads to duplication -- viz. the Maple Mini linker scripts are identical to the Maple's, and the olimex_stm32_h103 linker directory is just a symlink to Maple's. Clearly, the current structure is wrong. To fix it, instead of having per-board subdirectories of support/ld/, add per-MEMORY subdirectories of (new) support/ld/stm32/mem/. The per-board .mk files under support/mk/board-includes/ now reference these directly, and target-config.mk and the Makefile handle this appropriately. We move some other stuff around in target-config.mk to make this all more convenient, and even allow more overriding of the libmaple defaults on a per-board basis. Custom board hacks will be easier now. Unfortunately, lots of duplication under support/ld/stm32/mem/ is necessary, as the LENGTH attribute in a MEMORY region specification doesn't support arithmetic expressions, and ld doesn't seem to have any way to specify MEMORY at the command line (why?!). If we find a better way than this, we should do it. If a board (e.g. Maple Native) _does_ really need special memory-related configuration, you can always put a per-board subdirectory of support/ld/stm32/mem. We do this here to configure the heap.
