请教RAM分配 [复制链接]

各位大侠,小弟调试一款800*600的LCD时,OS系统文件DOWNLOAD进去就不能够显示正常:其中大约有2/5的显示是开机画面的前2/5部分.后面的显示就画屏.
请大家帮忙看看下面的设置是否正确?
若不正确,请问需要如何更改?根据什么进行更改?谢谢!!

这个看起来没什么问题，看看你的代码里有没有和你的DISPLAY 部分重叠的地址（AC1D0000）;
检查你的Lcd驱动，看看你分配的空间够不够；

dcyeahnet

LS的大侠,能够具体说说要看DISPLAY 部分重叠的地址（AC1D0000）在SMDK2440的哪些文件吗?
还有对于Lcd驱动，怎么确定分配的空间够不够?能够举例讲解一下吗?
本人还对WIN CE不熟悉,请多指点.
谢谢了.

修改config.bib中的DISPLAY所在行，例如640x480x16bpp的定义为:
DISPLAY 8c100000 00100000 RESERVED
其中8c100000是显存的地址, 00100000是显存的大小，640x480x 16(bit) = 640x480x2(byte) = 0x96000 byte ，注意这个显存的大小必须足够容纳你的分辨率需要的空间。而且要保证显存的地址+显存的大小不能够大于前面的NK的基地址(默认为8C200000)，显存的基地址也不能覆盖前面的节。

修改配置如下,结果依然和上面问题一样.

这不一定是config.bib里面的配置问题，你用的是哪家的屏，需要单独做初始化吗？可能还是场频、前肩、后肩那几个值的设定问题吧

我采用的是上海天马微电子的6.95"TTL的ＬＣＤ,不需要单独初始化.场频、前肩、后肩那几个值的设定应该是没有问题的,因为我用ADS编译的BOOT文件显示的开始画面都是正常的.

都已经Data Abort了，看一下OEMIint（）所在的那个启动文件（也就是IniyDisplay()函数所在的那个文件，好象是），是不是IO没映射好？猜测....
呵呵

今天看见一种怪异的想象。就是先前在4楼时配置的参数，昨天DOWNload进TARGET后，当然DNW显示就是10楼的结果。重启后，画面从开机画面跳进前面说的“其中大约有2/5的显示是开机画面的前2/5部分。”，然后就进入一个将LCD均匀4等分，左上显示白色，右上显示红色，左下显示绿色，右下显示蓝色。
今天下午拿出来准备重新DOWNload一个OS，上电又经历上面的过程，不过居然蹦出了WIN CE系统的操作界面。
后来重新断电、上电，就一直卡在“LCD均匀4等分，左上显示白色，右上显示红色，左下显示绿色，右下显示蓝色”，没有下文了。
传说中的“昙花”今日居然亲眼看见开花了。

对比了3.5"(320*240)和10.4打印出来的DNW信息,发现如下部分没有完成的初始化动作,因此OS系统也就不稳定,且部分功能没有动作.
请问这个是什么原因啊?要如何进行修改呢?

还我今生

你以前的屏幕是800*600的吗？
应该比这个小吧。
我觉得显存空间应该分配大一点，至少也要4M吧。

800*600*2都接近1M了。你都不知道这个显存都做了什么用。

回复：
以前的屏幕是320*240的，但是设定的显存空间（0.15MB）相对较小，
也只是适合320*240*2=0.1465<0.15MB(我调试3.5的显存设定值)。
对于800*600*2=0.916MB < 1MB
而我设定为1M，理论上讲，应该是没有问题的。

LS的说法有些具有片面性了，不过感谢你发言。
