Booting kernel with clean memory configuration:

Sp=ffffc7cc

[dm9: The mapped address is BE700000
[dm9: Chip signature is 0A469000

在Sp=ffffc7cc結束代表arminit 函式已執行結束
照理應該跳到kernelinit() 去執行,但卻沒有,而是跑到kmics.c去執行InitializeJit還有後來的網卡driver和Usb driver
怎麼會這樣呢

从Windows CE内核源代码来看,ARMInit走完一定会走KernelInit的,只不过你的debug message没有显示出来而已;
Build一个debug版的image,你就会看到"Windows CE KernelInit"这句话啦!

void
KernelInit(void)
{
#ifdef DEBUG
    lpWriteDebugStringFunc(TEXT("Windows CE KernelInit\r\n"));
#endif
    /* setup the well known system API sets & API types */
    SystemAPISets[SH_WIN32] = &cinfWin32;
    SystemAPISets[SH_CURTHREAD] = &cinfThread;
    SystemAPISets[SH_CURPROC] = &cinfProc;
    SystemAPISets[SH_CURTOKEN] = &cinfToken;
    SystemAPISets[HT_EVENT] = &cinfEvent;
    SystemAPISets[HT_MUTEX] = &cinfMutex;
    SystemAPISets[HT_SEMAPHORE] = &cinfSem;
                 ......

對,我也發現其實已經跑完kernelinit
而且到了SystemStartupFunc()
開始初始週邊設備的driver,如第一篇post的網路卡和usb
後來去查看platform.reg與platform.bib
但不知接下來要初始什麼設備..所以把不清楚的dll都註解掉
結果還是沒法啟動

最後發現停在KCall((PKFN)SetThreadBasePrio, hCurThread, THREAD_RT_PRIORITY_IDLE);
在schedule.c
