請教一個奇怪的現象
LDW
在WinCE50下移植了一個針對PXA255 CPU的BSP，現在有個奇怪的現象，就是儅OS
Image比較小的時候，系統能夠跑起來，儅OS大一點的時候，大概6M以上吧，就會出現如下的信息：
0 PID:0 TID:0 -OALKitlStart(rc = 1)
0 PID:0 TID:0 -OEMInit
0 PID:0 TID:0 MDValidateRomChain: XIP (ffffffff -> ffffffff) doesn't
exist in OEMAddressTable
0 PID:0 TID:0 ERROR! XIP region span accross discontigious memory!!!
System Halted!
0 PID:0 TID:0 Sp=ffffc7cc
這裡XIP(ffffffff -> ffffffff)地址由於OS大小的不同有改變。
看了g_oalAddressTable,和config.bib文件看不出來有什麽問題呀，大蝦們給各意見，這裡的XIP是怎麽囘事呢？我應該沒有定義XIP吧
