Raisonance Ride7 & ARM Tools (17) LPC2xxx の Startup (1): SYSLAB blog

Raisonance Ride7 & ARM Tools (17) LPC2xxx の Startup (1) ― 2012年09月20日 20時23分53秒

以前から気になっていた LPC2xxx 用のＳｔａｒｔｕｐ。RAISONANCE forums でも時々問題になっていた。この際少し調べてみることにする。
RAISONANCE オリジナルのＳｔａｒｔｕｐをそのまま使うと、どうやってもうまく動かない。
これは crt0_LPC23x.s の割り込みエントリー部分に不具合があるためで、その部分を使わなければ

__attribute__ ((interrupt("IRQ"))) void IRQHandler(void)
{
	if((T0IR &1) ==1){
		FIO1PIN2 ^= 0x04;
		T0IR=1;
	}
}

上記のように普通に書いて問題ない。
ここではせっかくなので、問題の割り込みエントリー部分をそのまま使う方法を考える。
もちろん一部修正は必要だ。

それでは修正の必要な crt0_LPC23x.s から
