看到J-Link官网上有ARM linux 上的烧录软件， 于是想用树莓派做主机来给产品烧录固件，于是新买了一个J-Link V8，从https://www.segger.com/downloads/jlink下载了JLink_Linux_V600i_arm.tgz， 把它放到树莓派上解压，这里就放下~目录下，新建一个jlink一个文件夹，把下载下来的文件放到里面解压：
|
1 |
pi@raspberrypi:~/jlink $ tar zxvf JLink_Linux_V600i_arm.tgz |
进入解压后的文件夹，看到有个README.txt, 先打看瞄瞄，原来为了让标准权根用户也可以用，要把一个文件放到指定文件夹，
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
pi@raspberrypi:~/jlink $ cd JLink_Linux_V600i_arm pi@raspberrypi:~/jlink/JLink_Linux_V600i_arm $ cat README.txt Requirements ============ libusb is no longer required. Running JLinkExe (or J-Link via USB in general) with standard user rights ========================================================================= In order to run JLinkExe with standard user rights you have to do the following: - Copy the file "99-jlink.rules" provided with this J-Link software package in the /etc/udev/rules.d/ directory using this command: sudo cp 99-jlink.rules /etc/udev/rules.d/ Note: For older systems it might be necessary to replace the "ATTRS" calls in the 99-jlink.rules by "SYSFS" calls - Restart your system |
于是照做，然后重启：

1 2 |
pi@raspberrypi:~/jlink/JLink_Linux_V600i_arm $ sudo cp 99-jlink.rules /etc/udev/rules.d/ pi@raspberrypi:~/jlink/JLink_Linux_V600i_arm $ sudo init 6 |
重启后, 第一次运行./JLinkExe, 发现固件会自动升级， 后面第二次运行就没有升级了：

S/N:一行做了处理，用xxxxxxxxx代替
看了2天的文档，终于知道如何只用一个命令完成烧录了。 新建一个文件1.sh, 写入以下内容，保存在跟JLinkExe同一个目录下，在调用JLinkExe时指定将烧录的芯片， 手头上刚好有上次做的小项目用到的STM32F103C8T6, 查了一下支持列表里只有STM32F103C8，就写成这个了。同时指定打开JLinkExe打开后要执行的命令脚本，随意写成了1.jlink.
1.sh文件：
|
1 2 |
#!/bin/bash ./JLinkExe -device STM32F103C8 -CommanderScript 1.jlink |
1.jlink文件:
|
1 2 3 4 5 |
si swd speed 4000 erase loadbin short_scanner.bin 0x08000000 SWDSelect qc |
这些是在下载的压缩包，解压后的JLink_Linux_V600i_arm/Doc/UM08001_JLink.pdf文件里找到的说明，89页：
然后给1.sh添加可执行权限, 就可以执行了，执行完后程就可以运行来下载程序到芯片上了：

可以看到烧录过程只要几秒钟，看来树莓派做这事还是蛮快的哈！上个合照：
再记录一下系统版本信息，感觉明年4代的树莓派，系统可能会上64位。
