define debug macro

in Configuration:

AC_ARG_ENABLE(debug,
AC_HELP_STRING([--enable-debug], [Enable debugging]),
CFLAGS="$CFLAGS -g -D_DEBUG")

Define:

#ifdef _DEBUG
#define DEBUG(format, args...) printf("[%s:%d] "format, __FILE__, __LINE__, ##args)
#else
#define DEBUG(args...)
#endif

Usage:

DEBUG("Debugging Mode was enabled\n")

Result:

[main.c:3] Debugging mode was enabled

Reference:
為你的程式加上 Debugging Mode

OMAP3530 devkit8000 boot:(一) x-loader/u-boot porting

devkit8000買了好一陣子, 最近總算把最新的x-loader+u-boot給弄了上去, 可以開始將之前的過程作一番記錄.

首先, 要先下載最新版的x-loader和u-boot
u-boot比較簡單, 從u-boot的官網下載就行. 我是從ftp下載下來的,
網址:ftp://ftp.denx.de/pub/u-boot/u-boot-latest.tar.bz2
這一包就是目前u-boot最新的版本.

x-loader可以從這邊下載
網址:http://gitorious.org/x-load-omap3
這個是for omap3的x-loader, 可以直接用這邊的作porting.

toolchain部份, 原本光碟附的是arm2007-q3.看了看 gcc -v的資訊後, 發現是從這裡下載的
網址:http://www.codesourcery.com/sgpp/lite_edition.html
這家公司提供了free的arm-gcc toolchain, 直接就可以拿來使用!
我是下載2010q1的版本作為porting依據.

接下來就是進行porting的動作了.
u-boot：
因為u-boot有把timll公司開發的devkit8000納到main trunk裡, 所以內建已經有支援devkit8000.
只要注意下列幾個地方

arch/arm/config.mk：
CROSS_COMPILE ?= /home/shaw/work/workspace/arm-2010q1/bin/arm-none-linux-gnueabi-

記得把cross compiler設定成先前下載的arm cross compiler

接著請參考Porting U-Boot issue(can't boot kernel with latest u-boot)
arm在boot kernel時,需要將MACH ID從u-boot傳到kernel中作比對,
在作porting時記得先比對kernel預設的MachID和bootloader所傳入的MachID是否相同

arch/arm/include/asm/mach-types.h：
#define MACH_TYPE_DEVKIT8000 2001 //for old kernel. The newest id value is 2330

我目前是改成2001, 要查詢最新的MachID可以到http://www.arm.linux.org.uk/developer/machines/查

接著只要輸入

make devkit8000_config
make

就可完成u-boot的建置.


x-loader部份, 從git下載下來的x-loader並沒有支援devkit8000, 需要改一些地方.
首先是建立devkit8000的程式碼, 由於devkit8000是beagleboard的clone, 所以只要使用beagleboard的程式碼作修改即可.

先修改Makefile:

CROSS_COMPILE = /home/shaw/work/workspace/arm-2010q1/bin/arm-none-linux-gnueabi-

跟u-boot一樣, 記得修改cross compiler的值

接著是加上devkit8000的config

omap3devkit8000_config: unconfig
@./mkconfig $(@:_config=) arm omap3 omap3devkit8000

修改完Makefile後, 加上devkit8000的board setting, 這裡有些設定有參考光碟內附的u-boot程式碼.

cp -a board/omap3530beagle/ board/omap3devkit8000/

修改board/omap3devkit8000/Makefile

OBJS := omap3devkit8000.o

修改檔名board/omap3devkit8000/omap3530beagle.c

mv board/omap3devkit8000/omap3530beagle.c board/omap3devkit8000/omap3devkit8000.c

修改board/omap3devkit8000/omap3devkit8000.c
需特別注意的地方為

int beagle_revision(void)

在devkit8000中, 此function會傳回0, 程式會誤認為目前的board為#define REVISION_XM 0x0
故此地方要特別留意.
下面把多加的值加上, 要加在哪再自己留意.

/* Devkit8000 revisions */
#define Devkit8000 0x1

int beagle_revision(void){
....
//Devkit8000 is 0, but 0 is meant beagleboard XM so change it to 1.
return Devkit8000;
}

int misc_init_r(void)
{
....
case Devkit8000:
printf("Devkit8000\n");
break;
....
}

修改完後, 接下來進行編譯

make omap3devkit8000_config
make

編譯完後, 記得將x-load.bin加上signGP的動作,signGP的程式碼網路上找一找就可以找到.

x-loader/u-boot的升版動作就此告一段落.
下一篇會解釋x-loader的開機流程, 順便介紹一下OMAP3530.

linux中的mstsc: XRDP

這陣子需要作一些程式的投影片, 必須從linux的電腦上截圖到投影片中.
一開始是使用VNC, 但總是會有頓頓的感覺, 而且這樣MSN/Skype會被路過的人看到....XD

研究了一下看看linux中有沒有什麼東西可以用起來很像windows server的mstsc, 多重的遠端桌面登入.
找到這個好物:XRDP

官網:http://xrdp.sourceforge.net/
XRDP也相容使用windows的mstsc來連接XRDP server. 用起來感覺很順.

在ubuntu裡, 直接輸入 apt-get install xrdp, 安裝完成!
目前使用上沒什麼特別問題, 之後再看看有什麼設定可以微調.

Fix:

The machine id in u-boot is not the same as in kernel.

u-boot:

#define MACH_TYPE_DEVKIT8000 2001 //for old kernel. The newest id value is 2330

安裝Fedora時, 出現無法辨識raid, 找不到硬碟?

在kernel commandline後面打nodmraid試看看

XDS100V2 連結 Devkit8000

最近開始進行板子上的實戰,
發現JTAG連接時會出現error, 經過一番奮鬥, 總算是有連結上, 把修改的地方記錄下:
1. 需下載CCSv4.1.2以上, 內部的Target選單才有XDS100V2及OMAP3530可以選擇.
2. 連結時把MMU關掉.(確認中)
3. 需修改etm_cortexA8_registers.gel, 我手上的Devkit8000版子, OMAP應該是ES3.x, 內部的cortexA8為R1P3版, 但etm_cortexA8_registers.gel裡並未定義CortexA8 R1P3, 將其補上就可消除Read ETM ID error.

Fujitsu S6510F Mini S-Video Cable Diy

上網研究了一下Fujistu S6510F的mini S-video線材diy,

找到一個大陸網站有寫製作方式, 花了半小時作了一條, 順便把線材的接腳連接方法記錄一下.

亮度<->Ring, 彩度<->Tip, GND<->GND.

接起來後就可以使用.

Devkit8000 (omap3530) 到手

先前訂的板子總算送到.

打開盒子拿出裡面附的光碟,
試著把裡面廠商build好的image放到SD卡裡,用SD卡作booting.

看了文件才發現要把SD卡切成2個partition.
第一個partition用FAT放loader,
第二個partition用EXT3放rootfs,
文件上還註明用ubuntu切partition時,
FAT磁區要用windows重新格式化才能開機.

弄到最後總算能順利開機,順便測試一下LCD.

接下來就要弄bootloader啦.
x-loader + u-boot.
