时间Sat Aug 9 21:51:24 2008
为什麽会产生GAP啊？这样很浪费空间说？能不能让他无GAP??

1F：推 zstar:有限制 code 的空间吗？或用 link 档将 function 定址 08/10 12:36
2F：→ zstar:ex. 倒数第二的 ICE_DOWNLOAD_SNL2 似乎是被刻意排在3800H 08/10 12:37
3F：→ zstar:而您的 code 尚未填满记忆体，自然有没使用到的 GAP。 08/10 12:39
4F：→ ast9869:CODE( ?PR?*?ICE(0x1200), ICE_SNL200_Parallel,...) 08/10 15:10
5F：→ ast9869:^^^^^^^^^^^^^==>打错了 0x2000才对 08/10 15:11
6F：→ ast9869:如果没有用?PR?*ICE(0x2000)的话，BL51会很Smart的帮你塞 08/10 15:13
7F：→ ast9869:塞到刚好，但还是会有GAP, 只是会很少GAP... 08/10 15:15
