[PATCH 0/5] Poradek v app/
by Michal Sojka 21 Jul '10

21 Jul '10

Ahoj, rozhodl jsem se udelat poradek v adresari app/, kde byla smes vselijakych testovacich programku pro ruzne desky a nikdo poradne nevedel co je k cemu dobre. Poradek jsem udelal tak, ze jsem uplne smazal aplikace v adresari app/arm/contrib a ostatni aplikace jsem rozstrkal do adresaru odpovidajicich desce ci mach(ine) pro kterou jsou urceny. Aplikace se tedy kompiluji automaticky jen kdyz je potreba a nemusi se kvuli tomu davat podminka do Makefile.omk. Pokud se vam neco na techto zmenach nezda, tak se ozvete. V opacnem pripade je za par dni poslu do repozitare. Michal Sojka (5): Spejbl: Set default linker script to an existing one Move applications to their board/mach subdirectory Remove contrib applications Remove conditional compilation from board/arch

[PATCH] Addded new mach-lpc17cmsis
by Jiri Kubias 21 Jul '10

21 Jul '10

This patch is only basic support for lpc17xx which is based on NXP port CMSIS from 25_jan_2010. The startup and LD file is taken from mach-lpc13xx and slightly updated for lpc17cmsis. In future the startup file may be changed to CMSIS startup file and LD script (which is not working with OMK now, so someone have to find out why it is not working) to be fully compatible with NXP demo examples. This mach can be used for generic develop for LPC17xx without CMSIS libraries. The disadvantage is that you must use NXP CMSIS header files whis is not so programator-friendly. --- arch/arm/mach-lpc17cmsis/Makefile | 14 + arch/arm/mach-lpc17cmsis/Makefile.omk | 1 + arch/arm/mach-lpc17cmsis/defines/LPC17xx.h | 1039 ++++++++++++++++++++ arch/arm/mach-lpc17cmsis/defines/Makefile | 14 + arch/arm/mach-lpc17cmsis/defines/Makefile.omk | 4 + arch/arm/mach-lpc17cmsis/defines/core_cm3.h | 978 ++++++++++++++++++ arch/arm/mach-lpc17cmsis/defines/lpc17xx.h | 1 + arch/arm/mach-lpc17cmsis/defines/lpc_types.h | 197 ++++ arch/arm/mach-lpc17cmsis/libs/Makefile | 14 + arch/arm/mach-lpc17cmsis/libs/Makefile.omk | 3 + arch/arm/mach-lpc17cmsis/libs/boot/Makefile | 14 + arch/arm/mach-lpc17cmsis/libs/boot/Makefile.omk | 3 + arch/arm/mach-lpc17cmsis/libs/boot/crt0_17xx.c | 241 +++++ arch/arm/mach-lpc17cmsis/libs/boot/initarray.c | 1 + arch/arm/mach-lpc17cmsis/libs/core/Makefile | 14 + arch/arm/mach-lpc17cmsis/libs/core/Makefile.omk | 5 + arch/arm/mach-lpc17cmsis/libs/core/core_cm3.c | 784 +++++++++++++++ arch/arm/mach-lpc17cmsis/libs/ldscripts/Makefile | 14 + .../mach-lpc17cmsis/libs/ldscripts/Makefile.omk | 3 + .../libs/ldscripts/lpc1768.ld-flash | 25 + .../libs/ldscripts/lpc17xx-flash.ld | 117 +++ 21 files changed, 3486 insertions(+), 0 deletions(-) create mode 100644 arch/arm/mach-lpc17cmsis/Makefile create mode 100644 arch/arm/mach-lpc17cmsis/Makefile.omk create mode 100644 arch/arm/mach-lpc17cmsis/defines/LPC17xx.h create mode 100644 arch/arm/mach-lpc17cmsis/defines/Makefile create mode 100644 arch/arm/mach-lpc17cmsis/defines/Makefile.omk create mode 100644 arch/arm/mach-lpc17cmsis/defines/core_cm3.h create mode 120000 arch/arm/mach-lpc17cmsis/defines/lpc17xx.h create mode 100644 arch/arm/mach-lpc17cmsis/defines/lpc_types.h create mode 100644 arch/arm/mach-lpc17cmsis/libs/Makefile create mode 100644 arch/arm/mach-lpc17cmsis/libs/Makefile.omk create mode 100644 arch/arm/mach-lpc17cmsis/libs/boot/Makefile create mode 100644 arch/arm/mach-lpc17cmsis/libs/boot/Makefile.omk create mode 100644 arch/arm/mach-lpc17cmsis/libs/boot/crt0_17xx.c create mode 120000 arch/arm/mach-lpc17cmsis/libs/boot/initarray.c create mode 100644 arch/arm/mach-lpc17cmsis/libs/core/Makefile create mode 100644 arch/arm/mach-lpc17cmsis/libs/core/Makefile.omk create mode 100644 arch/arm/mach-lpc17cmsis/libs/core/core_cm3.c create mode 100644 arch/arm/mach-lpc17cmsis/libs/ldscripts/Makefile create mode 100644 arch/arm/mach-lpc17cmsis/libs/ldscripts/Makefile.omk create mode 100644 arch/arm/mach-lpc17cmsis/libs/ldscripts/lpc1768.ld-flash create mode 100644 arch/arm/mach-lpc17cmsis/libs/ldscripts/lpc17xx-flash.ld diff --git a/arch/arm/mach-lpc17cmsis/Makefile b/arch/arm/mach-lpc17cmsis/Makefile new file mode 100644 index 0000000..76b56fd --- /dev/null +++ b/arch/arm/mach-lpc17cmsis/Makefile @@ -0,0 +1,14 @@ +# Generic directory or leaf node makefile for OCERA make framework + +ifndef MAKERULES_DIR +MAKERULES_DIR := $(shell ( old_pwd="" ; while [ ! -e Makefile.rules ] ; do if [ "$$old_pwd" = `pwd` ] ; then exit 1 ; else old_pwd=`pwd` ; cd -L .. 2>/dev/null ; fi ; done ; pwd ) ) +endif + +ifeq ($(MAKERULES_DIR),) +all : default +.DEFAULT:: + @echo -e "\nThe Makefile.rules has not been found in this or parent directory\n" +else +include $(MAKERULES_DIR)/Makefile.rules +endif + diff --git a/arch/arm/mach-lpc17cmsis/Makefile.omk b/arch/arm/mach-lpc17cmsis/Makefile.omk new file mode 100644 index 0000000..2ebd5c8 --- /dev/null +++ b/arch/arm/mach-lpc17cmsis/Makefile.omk @@ -0,0 +1 @@ +SUBDIRS = defines libs diff --git a/arch/arm/mach-lpc17cmsis/defines/LPC17xx.h b/arch/arm/mach-lpc17cmsis/defines/LPC17xx.h new file mode 100644 index 0000000..98bc137 --- /dev/null +++ b/arch/arm/mach-lpc17cmsis/defines/LPC17xx.h @@ -0,0 +1,1039 @@ +/**************************************************************************//** + * @file LPC17xx.h + * @brief CMSIS Cortex-M3 Core Peripheral Access Layer Header File for + * NXP LPC17xx Device Series + * @version V1.07 + * @date 19.

[PATCH] Added basic ARM & NXP CMSIS support
by jiri.kubias＠gmail.com (sysless＠pandora.cz) 20 Jul '10

20 Jul '10

Added new mach lpc17cmsis, successfully added some libs from CMSIS Added new board for mbed development kit Added app for test mbed_led blink Added app cmsis-test which send out 0xAA to UART3 and send some dummy message to CAN2 at 125kbit TODO: * exclude board config file from mach * add more libs from CMSIS * support direct loading app to microprocessor Patch je moc veliky pro pandoru, posilam ho primo Michalovi. Patch file is too big for pandora, Im sendig it directly to Michal Sojka JIrka -- =================================================== Bc. Jiri Kubias Czech Technical University in Prague Faculty of Electrical Engineering dept. of Control Engineering Karlovo namesti 13/E, 121 35 Prague Czech Republic web page: http://dce.felk.cvut.cz e-mail: jiri.kubias(a)gmail.com mobile: 777 974167 =================================================== ---

Automaticky build pro vsechny desky

Ahoj, aby nam ten sysless tak moc neuhnival, tak jsem vytvoril repozitar sysless-build-all, kde jsou ve zvlastnich adresarich buildy pro vsechny existujici desky a jednim prikazem make se da otestovat, jestli jde vsechno zkompilovat. Soucasny stav je takovy, ze toho spousta zkompilovat nejde. Az budu mit vic casu, tak zacnu resit jake to ma duvody. Potom, az vsechno bude zkompilovatelne, nebudu prijimat patche, ktere zpusobi, ze neco prestane byt zkompilovatelne. Na detaily se muzete podivat na http://rtime.felk.cvut.cz/gitweb/sysless-build-all.git Navod k pouziti: git clone git://rtime.felk.cvut.cz/sysless-build-all.git cd sysless-build-all ln -s <cesta-k-syslessu> src make Argumenty prikazu make jsou predany do vsech podadresaru, takze napr. "make distclean" provede distclean v adresarich vsech desek. Chyby lze ignorovat tradicne pomoci make -k. -Michal ---

Bohuzel se mi nedari zlomit mach-lpc17xx a ani ma portace mach-lpc17cmsis k funkcnosti. Ale povedlo se mi pomerne rychle a jednoduse zlomit Markuv mach-lpc13xx na novy mach-17xx (s funkcni demo aplikaci ktera blika ledkou). Otazka je tedy co s tim? Smazat soucasnou verzi lpc17xx a nahradit upravenou Markovou, nebo pockat az se spravce soucasne verze ozve? Jak uz psal Marek lpc17xx a lpc13xx maje stejne jadro, takze zaklad je uplne stejny...
