Fork of mbed-src by mbed official

Information

この情報は2013/10/28時点での解決方法です。
現在はmbed-src、標準ライブラリで問題なくコンパイルが可能です。

・使う物
LPC1114FN28
mbed SDK

LPC1114FN28でmbed-SDKのLibraryを使うとCompile出来ない。（2013/10/28） /media/uploads/minicube/mbed_lpc1114_sdk.png

パスが通ってないだけのようなのでファイルを以下に移動する。

mbed-src\targets\cmsis\TARGET_NXP\TARGET_LPC11XX_11CXX\
mbed-src\targets\cmsis\TARGET_NXP\TARGET_LPC11XX_11CXX\TARGET_LPC11XX\

にあるファイルをすべて

mbed-src\targets\cmsis\TARGET_NXP\

へ移動

mbed-src\targets\cmsis\TARGET_NXP\TARGET_LPC11XX_11CXX\にある

TOOLCHAIN_ARM_MICRO

をフォルダごと

mbed-src\targets\cmsis\TARGET_NXP\

へ移動

mbed-src\targets\hal\TARGET_NXP\TARGET_LPC11XX_11CXX\
mbed-src\targets\hal\TARGET_NXP\TARGET_LPC11XX_11CXX\TARGET_LPC11XX\

にあるファイルをすべて

mbed-src\targets\hal\TARGET_NXP\

へ移動

移動後は以下のような構成になると思います。
※不要なファイルは削除してあります。

/media/uploads/minicube/mbed_lpc1114_sdk_tree.png


ファイルの移動が面倒なので以下に本家からフォークしたライブラリを置いておきます。

エラーが出力される場合

"TOOLCHAIN_ARM_MICRO"が無いとエラーになる。

Error: Undefined symbol _initial_sp (referred from entry2.o).
Error: Undefined symbol _heap_base (referred from malloc.o).
Error: Undefined symbol _heap_limit (referred from malloc.o).

LPC1114FN28はMicrolibを使ってCompileされるため上記のエラーになるようです。
