使用串口或JTAG烧录F240芯片,整个烧录过程成功.但是通过CCS观察程序内容时,发现地址0000~0FFF内容全都是FF(没有数据,待烧录的OUT文件此期间是有数据的),而1FFF~3FFF地址内容正确.真的很奇怪. 有哪些方面会引起这些问题呢
use RS-232 or JTAG to download the F240 flash, the total steps are right and successful. But find the contents of the address (0000h~3FFFh) are empty (That is FF) and the contentsof the address (1000h~3fffh) are right(That is no empty) by CCS software viewing program space. it is very strange. which sides can affect this question? Can you help me?

请问楼主是每个芯片烧写都有这个问题呢还是只有一个芯片有这个问题?是否你在烧录的时候FLASH 扇区没有全部选上?
