aspカーネルの簡易パッケージのasp_nucleo_f401re_gcc-2017211.zipまたはasp_arduuino_m0_gcc-20151128.zip中のCortex-M0用のアセンブラ・コードのcore_support_v6m.S中の164行から169行目の
164 ldr r3, =iipm /* 後で使用するため読み込む /
165 ldrb r0, [r3]
166 mrs r2, primask / CPUロック状態ならカーネル管理外例外処理へ */
167 cmp r1, #1
168 beq core_nonkernel_exc_entry
の167行目のcmp r1,#1はcmp r2,#1の間違いではないですか?
