수정중
Memory Map 과 구조도 및 Firmware 이해 필요,
Linux File system 부분 수정 부분
1.1 GCC Tool Chain and SDK Download
- arm-2009q1-203-arm-none-linux-gnueabi.bin (Code Sourcery ARM GCC Tool Chain)
- ezsdk_dm814x-evm_5_05_02_00_setuplinux
1.2 개발환경구성
- 환경변수 재설정
보고 필요한부분을 넣었다.
기본정의 Rule.make에 정의가 되어있으면 동작이 제대로 되어야겠지만,
본인이 원하는 대로 동작이 안된다면, 두 파일을 비교하여 오동작되는 부분을 파악해서
환경변수 고치던지 하는것이 편할 것이다.
나는 source 를 이용하여 아래와 같이 그냥 외부에서 설정을 해놓았다.
$ vi setPATH.sh
#!/bin/sh
# source setPATH.sh
# INSTALL_MOD_PATH : Kernel Module
# SYSLINK_INSTALL_DIR : syslink.ko
export PATH=$PATH:/home/jhlee/dm8148/CodeSourcery/Sourcery_G++_Lite/bin
export EZSDK="${HOME}/dm8148/ti-ezsdk_dm814x-evm_xx_xx_xx_xx"
export CROSS_COMPILE=arm-none-linux-gnueabi-
export ARCH=arm
export INSTALL_MOD_PATH="${HOME}/dm8148/targetfs" // Kernel module
$ source setPATH.sh
- 개발환경구성설정 (TI에서 제공)
- NFS Server 환경구성
- TFTP 설정
$ cd ~/dm8148/ti-ezsdk_dm814x-evm_5_05_02_00 $./setup.sh // 자동으로 설정 NFS/TFTP
1.3 EZSDK 설치시 구조 및 빌드방법

상위문제 Linux Kernel 사용이 되는 필요없는 Config를 제거하여 문제해결
현재 나의 Board가 EVM이 아니기 때문에 Kernel config를 점검해가면서 수정해서
필요 없는 부분을 제거하고 변경하고 TEST 하자.
