个性LGT仿真器打造 & 在Ubuntu下使用攻略
本帖最后由 xwkm 于 2013-1-3 02:44 编辑首先就是在阿莫这里买一块仿真器，或者自己拿新唐的片子写一个(那个SWD时钟看得头大没分析出来协议），把那个U盘的bootloader写入就行。
然后用镊子捅仿真器的J4。
按住镊子不要动，然后插上仿真器看到
后拿下镊子到mcugreen.com下载最新的SWDICE mkII studio 4版本。别搞错了。搞错了avrdude和avarice不支持！
把bin文件复制进去。点弹出，拔下USB线再插上就搞定了固件了。
顺带说下上次我申请的仿真器有一处小瑕疵，看R20给焊反了……
安装驱动程序：
打开终端，输入：
sudo gedit /etc/udev/rules.d/60-avrmkii.rules
在打开的窗口中复制下面内容粘贴然后保存
SUBSYSTEM!="usb_device", ACTION!="add", GOTO="avrisp_end"
# Atmel Corp. JTAG ICE mkII
ATTR{idVendor}=="03eb", SYSFS{idProduct}=="2103", MODE="660", GROUP="dialout"
# Atmel Corp. AVRISP mkII
ATTR{idVendor}=="03eb", SYSFS{idProduct}=="2104", MODE="660", GROUP="dialout"
# Atmel Corp. Dragon
ATTR{idVendor}=="03eb", SYSFS{idProduct}=="2107", MODE="660", GROUP="dialout"
LABEL="avrisp_end"
接着执行
sudo restart udevd
然后后面就简单了。avrdude该怎么用怎么用，不过注意一下，因为LGT的仿真器报告的ID是164P的，所以avrdude也必须只能用164P的ID.
而且仿真器报告的熔丝avrdude认为不是安全的，所以需要-F来强制写入。
比如说这个命令就是可行的：
avrdude -p m164p -c jtag2 -P usb -F -e -U flash:w:XXXX.hex
另外就是avarice同样也是可以使用的，输入如下命令：
avarice --program--file xxxx.elf --part atmega164p --mkII -j usb localhost:4242
接着可以用gdb调，教程一搜一大把。我就不讲了。
现在真心希望官方把ISP时序开源了。毕竟连着这个“mkII”总是觉得怪怪的……
顺带换了LED：RUN、POWER变翠绿了。
支持一下！很不错！！！ 收藏备用。
谢谢楼主 顺带说下。如果嫌avrdude没有lgt8f08a太难看的话。打开/etc/avrdude.conf。加入：

然后就可以使用-p l8a了 顺带提醒一下。SWD和SWC上的上拉电阻至少要更换成4.7k的。否则极易被干扰，导致程序无法写入。不过这次我硬上用0805电阻焊到了0603焊盘上…… avrdude对LGT mkII的支持相当不好，建议使用avarice来高。虽然说写eeprom不太方便。
avarice --program--erase --file kmlamp.elf --part atmega164p --mkII -j usb 标记一下，备用 你好，请问“首先就是在阿莫这里买一块仿真器，或者自己拿新唐的片子写一个(那个SWD时钟看得头大没分析出来协议），把那个U盘的bootloader写入就行。
然后用镊子捅仿真器的J4。”
U盘的bootloader的固件哪里能找到？

你好，请问“首先就是在阿莫这里买一块仿真器，或者自己拿新唐的片子写一个(那个SWD时钟看得头大没分析出来 ...
在LGT分坛里搜索“仿真器 升级”即可。有boot的固件。如果你直接买仿真器的话就不用bootloader 如此好贴，今天才看到{:lol:}
多谢！！ 楼主强人啊，唯鲁有才。
