硬件问题

接入键盘输入后,为什么LCD无响应?

EmbestDevkit8500 3.JPG

情况:
刚收到开发板,心情异常激动,立马拿出配套电源连接开发板上电,发现LCD出现一企鹅跟一串文字,后面写着“xxxx login: ”,接上USB键盘,竟然没有反应!
解答:
首先这个是一个正常的现象,对于预装的系统,我们采用的是一个简易版的文件系统,此文件系统不包括将USB、串口等设备的字符传输到LCD的功能。
用户可以接上调试串口,打开电脑端的超级终端实现串口通信交互。

NAND flash被擦除,如何启动系统?

假若NAND flash系统被擦除了,用户可以使用SD卡启动系统,因为omap35x芯片是支持在SD卡上启动x-loader,可以按照用户手册的SD卡系统映像更新一节。

怎么让USB OTG口工作于主、从方式?

A:在内核启动前,如果要让USB OTG工作于主方式,则板载USB OTG接套件提供的USB A型线;如果要让USB OTG工作于从方式,则板载USB OTG接套件提供的USB B型线。

如何切换到MMC/SD启动开发板?

A:按住BOOT按键,上电启动,系统改为先从MMC/SD启动,再从NAND启动,详细请参考“3.18按键”介绍。

DevKit8000如何调试DSP和ARM?

1.与仿真器相连接: 我们有用于TI 公司C2000、C5000、C6000芯片及OMAP、DaVinci、ARM7、ARM9 的仿真器,具体型号为TDS560,XDS100V2等,可以参考: http://www.timll.com/chinese/product/TDS560.asp
http://www.timll.com/chinese/product/XDS100.asp
2.在软件系统上调试: 用户可以参考原光盘上所提供的DEMO-DVSDK,DVSDK上提供了完整的视频格式编码,解码的驱动,用户只需要调试DSP上的算法即可以使用,并且有完整的用户手册,具体可以参考:
http://focus.ti.com/docs/toolsw/folders/print/linuxdvsdk-omap3530.html

DevKit8000中的RTC电池型号是多少?

DevKit8000出货时不带RTC电池,需用户自行配备,电池型号用 CR1220即可

linux问题

若开发板的nand flash被擦除,该如何恢复出厂的状态?/ If the NandFlash had erased,how to restore it?

Chinese:
若遇到这种情况,请将先下载 linux_WriteToNandflash.rar,解压该压缩包,将里面的所有文件拷贝到SD卡里,然后从SD卡启动。

注意:请确认你之前在u-boot命令行下是否有使用过saveenv指令,若有使用过,请在u-boot命令行下输入 nand erase,再重新启动即可。

English:
Please download the linux_WriteToNandflash.rar,and decompression the linux_WriteToNandflash.rar,copy the all file to the SD card in the linux_WriteToNandflash.rar,boot the image for the SD card.

Notes: If your NandFlash had OS before, please erase it, enter to the u-boot prompts and input the commands of "nand erase" to erase the NandFlash.

开发驱动时如何打开低层调试信息?

基于linux的原因,当linux的内核启动之后它会在内部操作完所有设备的初始化,对于用户使用最小系统来开发扩展板,需要打开实时的调试信息,查出哪里出现bug,具体的打开方式如下:
在内核根目录下,
1. make omap3_devkit8000_defconfig
2. make menucofig
在内核定制目录下选上“Kernel low-level debugging functions”

Symbol: DEBUG_LL [=y] 
Prompt: Kernel low-level debugging functions
Defined at arch/arm/Kconfig.debug:54
Depends on: DEBUG_KERNEL
Location:
-> Kernel hacking

3. make uImage
编译后生成的uImage文件直接使用即可。

如何让显示输出在lcd屏与DVI输出之间切换?

A:只需修改内核启动参数即可.

  1. ---------------------------------------------
  2. Disable power management
  3. (Requires sysfs support in the kernel)
  4. ---------------------------------------------

echo -n " Disabling Power mgmt  : "
echo -n "1" > /sys/power/cpuidle_deepest_state
status $? 1

  1. ---------------------------------------------
  2. Turn off LCD after 1 hour of inactivity
  3. (Requires sysfs support in the kernel)
  4. ---------------------------------------------

echo -n " Turn off LCD after 1 hour  : "
echo -n "0" > /sys/power/fb_timeout_value
status $? 1

则可以解决linux关屏问题。

S-Video输出的使用方法

首先请重新编译内核,在内核配置的选项选上:

 Multimedia devices  --->
[*] Video capture adapters --->
VID1 Overlay manager (Use TV Managaer) --->
(X) Use TV Manager

选上后重新编译,并将生成的uImage放入sd卡,开始启动系统。
重新编译后,你需要下载测试工具video_test与范例视频foreman_vga_422.yuv,您可在http://code.google.com/p/devkit8000/downloads/list找到。

进入内核后输入:
拷贝video_test与foreman_vga_422.yuv文件到板子空间里,运行方法如下:
video_test /foreman_vga_422.yuv

设置开机自动执行命令的方法

修改文件系统的/etc/init.d/rcS文件,添加你要执行的命令,即可实现开机自动执行命令。命令后面添加&符号可以实现开机自动后台执行命令。

复用GPIO的配置方法

在board/omap3devkit8000/omap3devkit8000.c的MUX_DEFAULT_ES2下进行配置,具体配置方法请参考OMAP3530 datasheet的第7章“System Control Module”。

wince问题

烧写wince到NAND Flash系统映像更新

1.更新文件准备
(1) 用软件HP Disk Storage Format Tool格式化SD卡为FAT或FAT32文件系统。
(2) 拷贝光盘目录image[\wince_6]下子目录dvi1280X720或lcd480X272下文件MLO、EBOOTNAND.nb0、NK.bin、XLDRNAND.nb0和ADevKit9000.exe到SD卡并重命名EBOOTNAND.nb0为EBOOTSD.nb0

屏蔽WinCE启动后的触摸屏打印信息

修改函数DevKit8000\SRC\DRIVERS\TOUCH\touchscreen.cpp, 把564行 RETAILMSG(1, ( TEXT( "Point: (%d,%d)\r\n" ), *pUncalX, *pUncalY ) ); 屏蔽掉然后重新编译就行了。如下所示: //RETAILMSG(1, ( TEXT( "Point: (%d,%d)\r\n" ), *pUncalX, *pUncalY ) );

关闭调试串口打印

setp:
1,comment out the RETAILMSG call in TouchDriverCalibrationPointGet function of touchscreen.cpp
2,comment out the RETAILMSG call in DdsiTouchPanelGetPoint function of touchscreen.cpp
3,comment out the RETAILMSG call in TLED_Backlight::SetPowerState function of tled_backlight.cpp
4,comment out the RETAILMSG call in SetDutyCycle function of tled.cpp
5,comment out the RETAILMSG call in LcdPdd_LCD_Initialize function of lcd_vga.c
6,make sure that "set BSP_NOCOM=" is not set in DevKit8000.bat
7,make sure that "set BSP_NOCOM3=" is not set in DevKit8000.bat
8,delete the "IF BSP_COM3" of _FLATRELEASEDIR/platform.reg in line 1103
9,delete the "ENDIF BSP_COM3" of _FLATRELEASEDIR/platform.reg in line 1124
10,rebuild the BSP

关闭触摸屏校准

setp:
在BSP包的一级目录下,有DevKit8000.bat文件,在其中任一行添加:
set IMGNOCALIBRATION=1
然后重新build编译即可

关于触摸屏不能用的问题解决方法

是编译时使用 build and sysgen导致的,在wince下不能用bulid and sysgen编译,用它就出问题,而且必须把pb6.0重装才可以

WINCE无法存储

在SRC\DRIVERS\BLOCK\NAND\nand_MT29F2G16.h 把下面这句

  1. define NUMBER_OF_BLOCKS (2048) // 2048 blocks

改成

  1. define NUMBER_OF_BLOCKS (1024) // 1024 blocks

如何修正RTC时间不准确的问题/ How to correct the right RTC functions

Chinese:
1. 把新的rtc.c替换原来的src/oal/oalrtc/rtc.c(http://devkit8000.googlecode.com/files/rtc.c)

2. 在src/inc/bsp_cfg.h后面加上#define BSP_OAL_RTC_USES_TWL4030 TRUE

3. 重新编译。


English:
1. Please replace the src/oal/oalrtc/rtc.c as the new rtc.c (http://devkit8000.googlecode.com/files/rtc.c)

2. Add the #define BSP_OAL_RTC_USES_TWL4030 TRUE on the src/inc/bsp_cfg.h in BSP.

3. Recompile the image again.

如何修改WINCE的MAC地址

直接修改改注册表
[HKEY_LOCAL_MACHINE\Comm\DM9CE1\Parms]
"BusNumber"=dword:0
"BusType"=dword:1
"XmitBuffer"=dword:20
"RecvBuffer"=dword:20
"IrqNumber"=dword:99
"IoAddress"=dword:15000000
"Mac"=hex:00,00,00,00,00,00

通过SD卡启动不了Wince的解决方法

若你的串口信息有出现以下内容:
HandleInsertion
MMC Reset
MMCIssueIdentify: SD card detected
SD card relative address is 26803
MMCIssueIdentify: CSD
reported block size = 512
Card size is = 972800 512 byte sectors

Download file type: 1
ERROR: Checksum failure (expected=0x1768BE9 computed=0x170C19B)
****** Checksum failure on record 5, ABORT!!! ******
若遇到这种情况,请您将光盘里面的NK.bin文件重新放入SD卡里面,便可以解决。

如何建立KITL连接?

目前DevKit8000只支持DM9000网络下载nk.bin,不支持KITL传输,这是由于DM9000的bootloader和OAL公共部分代码在进wince系统后地址空间没进行地址映射直接访问DM9000的物理地址造成的,这个问题待修正。
使用USB RNDIS可进行nk.bin下载和KITL传输。

 1.在PC安装微软RNDIS驱动。
2.设置虚拟网卡的IP地址和DevKit8000的IP地址,并确保它们在同一网段且不和PC机同一网段。
3.在Eboot设置启动设备了USB RNDIS,选择调试设备为USB RNDIS。

启动WinCE时出现BP_ReadData call failed的解决方法

(1) 用软件HP Disk Storage Format Tool格式化SD卡为FAT或FAT32文件系统。
(2) 拷贝光盘目录image[\wince_6]下子目录dvi1280X720或lcd480X272下文件
MLO, EBOOTNAND.nb0, NK.bin, XLDRNAND.nb0, ADevKit8000.exe到SD卡,将EBOOTNAND.nb0改名为EBOOTSD.nb0。
(3) 按着BOOT键,当串口显示:
INFO: Boot configuration found
OALFlashStoreOpen: 2048 blocks, 64 sectors/block
OALFlashStoreOpen: 2048 bytes/sector, 14 reserved blocks
ERROR: OALFlashStoreRead: Failed read sector 384 (0 sector in block 6)
Hit space to enter configuration menu 1... 请在这里按空格键
按[5]进入Flash管理菜单。
注意:若是按[8]才是Flash管理菜单的话,那是不正确的,说明您没有操作上一步的“将EBOOTNAND.nb0改名为EBOOTSD.nb0”。
(4) 按[3]进入Flash erase。
等待完成后再进行下一步。
(5) 按[7]进入Flash format。
等待完成后再进行下一步。
(6) 再执行用户手册的12.2.1 NAND Flash系统映象更新。

复用GPIO的配置方法

DeviceIoControl(hFile, IOCTL_GPIO_SETBIT, &id, sizeof(DWORD), 0, 0, NULL, NULL);

1.You have to modify the ID to GPIO number
2.You have to modify the file platform.c (C:\WINCE600\DevKit8000\BSP\DevKit8000\SRC\BOOT\XLDR). you have to enable the PIN mux mode:

 /*MMC2*/
// Implemented on expansion interface only - leave disabled //OUTREG16(&pConfig->CONTROL_PADCONF_MMC2_CLK, (INPUT_DISABLE | PULL_UP | MUX_MODE_0)); /*MMC2_CLK*/ //OUTREG16(&pConfig->CONTROL_PADCONF_MMC2_CMD, (INPUT_ENABLE | PULL_UP | MUX_MODE_0)); /*MMC2_CMD*/ //OUTREG16(&pConfig->CONTROL_PADCONF_MMC2_DAT0, (INPUT_ENABLE | PULL_UP | MUX_MODE_0)); /*MMC2_DAT0*/ //OUTREG16(&pConfig->CONTROL_PADCONF_MMC2_DAT1, (INPUT_ENABLE | PULL_UP | MUX_MODE_0)); /*MMC2_DAT1*/ //OUTREG16(&pConfig->CONTROL_PADCONF_MMC2_DAT2, (INPUT_ENABLE | PULL_UP | MUX_MODE_0)); /*MMC2_DAT2*/ //OUTREG16(&pConfig->CONTROL_PADCONF_MMC2_DAT3, (INPUT_ENABLE | PULL_UP | MUX_MODE_0)); /*MMC2_DAT3*/

固定触摸屏大小

1. you have to get the "CalibrationData", you can enter your wince via calibration, use the "Regedit.exe" to open the regedit, open the directory of [HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\TOUCH] and check the "CalibrationData"=" xxxxxxxx "

2.open the "\BSP\DevKit8000\FILES\platform.reg" with visual studio 2005:

如何划分DEMO用的SD卡

下次分区可以采用这个方法,一直可用:

1 先用HP格式化工具把卡格式化一次

2 进入ubuntu系统后,执行以下命令分区

 sudo fdisk /dev/sdb < fdisk-list-xxx

Ps:fdisk-list-xxx从这里下载
用于512MB的SD卡的fdisk-lisk文件:http://devkit8000.googlecode.com/files/fdisk-list-512M
用于2G的SD卡的fdisk-lisk文件:http://devkit8000.googlecode.com/files/fdisk-list-2GB

3 根据你的卡容量使用不同的配置文件,第一分区的容量可以修改fdisk-list-xx文件里面的信息

4 输入下面指令:

 sudo mkfs.msdos -F 32 /dev/sdb1 -n LABEL1
sudo mkfs.ext3 -L LABEL2 /dev/sdb2

5 安全移除SD卡,重新拔插,让Linux系统重新挂载一次第二分区(或者ubuntu会帮你自动挂载),否则SD卡后会变得不可用。
6 在Windows操作系统下使用自带的格式化工具格式化SD卡(格式化FAT分区,因在Windows系统下不识别ext3分区)。

提供demo配套u-boot.bin无法修改参数

提供demo配套u-boot.bin无法修改参数,用户想要修改并保存u-boot下参数,可采用DevKit8000提供u-boot源码,修改传递给内核的MACH_ID,重新编译即可。
具体操作方法:
1、u-boot-1.3.3源码中
修改board/omap3devkit8000/omap3devkit8000.c文件
找到board_init函数
修改:
gd->bd->bi_arch_number = MACH_TYPE_DEVKIT8000;为
gd->bd->bi_arch_number = XXX;

2、重新编译u-boot

注:

   1、对于angstrom,XXX为MACH_TYPE_DEVKIT8000
   2、对于android,XXX为MACH_TYPE_OMAP3_BEAGLE
   3、对于dvsdk,XXX为MACH_TYPE_OMAP3EVM

DevKit8000跑QT程序鼠标不工作

内核目录下输入make menuconfig,添加如下配置:

Device Drivers ---> Input device support --->

<*>Mouse interface

[*]Provide legacy /dev/psaux device

(1024) Horizontal screen resolution

(768) Vertical screen resolution

[*] Mice --->
