【F.A.Q】
1Q:贵站的mkII-CN为什么会这么便宜?性能会打折扣么?
1A
:本站的mkII-CN采用的是自主硬件设计,可以有效控制成本,并简化了原装mkII中完全没有必要的冗余电路,使得数据可以更好更快的传递,从而在实现兼容的前提下提升一定的性能。本站自主设计的硬件电路成本比原装低很多,成本控制好了价格自然也可以下来,让广大用户得到实惠。
2Q:贵站的mkII-CN如何保证没有bug?在出现bug后如何进行修正?修正需要多长时间?
2A
:本站分析研究mkII已经有整整两年时间,mkII-CN这个产品不是凭空设计的,而是经过我们很长时间的分析和研究的,经过几个内部版本和几个月的测试,目前已经可以说非常可靠和稳定,当然我们不可能保证100%的不出bug。一旦客户发现bug,请与我们及时沟通,我们在确认bug后会在第一时间进行修正,一般bug的确认和解决不会超过3个工作日。
3Q:为什么说mkII-CN的速度要比原装的快?
3A
:mkII-CN不光从硬件上优化了电路设计,更从软件上进行了较大程度的优化,有效的控制了数据链路长度,从而有效的提高了编程速度。有条件的用户可以与原装对比一下ISP和JTAG的编程速度。
4Q:我不小心将原装的固件升级到了mkII-CN,我该怎么办?
4A
:请不用担心。你只需要重新运行一遍升级操作就可以了,请使用我们发布的固件。为了方便固件升级,我们发布了一个升级软件,通过该软件,可以方便的选择仿真器型号和固件版本,然后即可进行升级,且该软件并不破坏原装固件。
5Q:mkII-CN会不会被ATMEL认为是盗版产品而通过序列号进行封杀?
5A
:mkII-CN是一个自主设计的反向工程产品,ATMEL原厂工程师及其一级代理商均认可了这款产品。对ATMEL而言,我们是第三方工具供应商,ATMEL会以积极的态度接受我们的产品。同时,由于mkII-CN的升级固件是我们自己发布的,协议也是我们自己编写的,所以不必担心来自ATMEL方面的技术封杀。倒是那些clone
mkII比较容易受限制。
6Q:如何保证及时发布固件?
6A
:mkII-CN是我们自行设计的产品,我们对AVR/AVR32的调试协议已经全部掌握,所以在ATMEL发布新版本固件后,我们会在第一时间发布适合我们mkII-CN的新版固件。新固件版本的编写不超过1个工作日。如果ATMEL发布新版本固件,请及时告知我们,谢谢。
7Q:我想在一台电脑上连接多个mkII-CN,可以么?
7A
:每个mkII-CN都有一个独立的序列号,所以可以方便的连接多个mkII-CN,AVRSTUDIO/AVR32STUDIO会提示你连接哪个mkII-CN。
8Q:mkII-CN的功耗大么?需要外接电源么?
8A
:mkII-CN的功耗很低,不需要外接电源,通过USB
1.1供电就足够了。原装的mkII由于电路复杂,功耗比较大,如果USB功能能力较弱(比如USB
1.1的PC)或者USB线缆线阻较大就会出现供电不足的情况。所以原装mkII预留了一个外部电源接口,而mkII-CN尾部的外部电源接口是不需要使用的,也没有实际电路,只是一个装饰。
9Q:mkII-CN的保护电路设计的如何?
9A
:mkII-CN在USB端口和目标板接口上都设计了保护电路。USB端口有一个自复位的过流保护,可以有效保护PC机USB端口和仿真器。目标板接口上采用较为复杂的保护电路,当电源供应不对,比如ISP和JTAG插反的情况下,接口电路是不工作的,从而有效保护接口电路。
10Q:mkII-CN采用的是什么接口?需要安装驱动么?
10A
:mkII-CN采用的是真正USB接口,尾部的串口是装饰物,并无实际功能,mkII-CN使用的是和原装一样的驱动,在安装AVRSTUDIO的时候只需要勾选自带的驱动即可。AVRSTUDIO安装完毕后插上mkII-CN,当PC提示安装驱动的时候只需要自动安装即可。

【F.A.Q】
1Q:
Why mkII-CN so cheap? Does this mean low price, low
performance?
1A
: mkII-CN is designed by ourself,
remove the un-used circuit from the original mkII from ATMEL, this
has two advantages: less components, faster communication speed.
Though the hardware is not the same as the original one, the
functionality is all the same. So the customers can by this use less
money.
2Q:
How can you ensure your own design is fully compatible with the
ATMEL one? If there is a bug, how to fix it?
2A
: We analyzed the
original products for 2 years. And we tested several versions before
mass products. We can not guarantee there is no bug, but we
guarantee that we will delivery the fix as soon as the customer find
a bug.
3Q:
Why mkII-CN is faster than mkII from ATMEL?
3A
: Compare with the
original one, mkII-CN has a simple hardware, this will reduce the
signal latency. On the other hand, we optimize the software, to
imporve the programming speed. You can compare the programing speed
(via ISP or JTAG) with original one, and send back your results,
thanks.
4Q:
How can I do if I update the mkII-CN with the firmware from
ATMEL?
4A
: Don't worry. Please re-update the
mkII-CN with the firmware distribute by us. We have provided a
software tools. Use this tool, you can update your mkII-CN freely.
5Q:
Does there is an issue, mkII-CN will be disabled in AVRStudio by
ATMEL, since ATMEL may treat it as pirate?
5A
: mkII-CN is approved
by ATMEL engineer and be selected as tool by some distributor. Most
important is, mkII-CN is designed by ourself, both hardware &
software, not a CLONE to the original
products.
6Q:
How to ensure you can delivery the firmware timely?
6A
: We promise to issue
new firmware within 3 working days after ATMEL release new AVRstudio
or for bug fixing. Communicate us if you found there is a updated
from ATMEL.
7Q:
Can I connect multiple mkII-CN to one PC?
7A
: Each mkII-CN has its
own SN, so you can do this as you wish. Just make sure you choose
the right one in AVRStudio.
8Q:
Dose mkII-CN need stand alone power supply?
8A
: It is enough to
power the mkII-CN with USB. Do not connect power supply to mkII-CN,
that power jack is useless.
9Q:
Does mkII-CN has a protect circuit on the connect interface, how
about it?
9A
: mkII-CN has protect circuit for both
USB & target interfaces. USB port has a over-current protect
fuse(self recovery), this can protect the PC USB port. The protect
circuit for target connection port is more complex. It will not work
if the target power is not OK, e.g., the ISP/JTAG is not properly
connected.
10Q:
Which port used to connect mkII-CN to PC? Does special driver
needed?
10A
: mkII-CN use USB interface connect
to PC, not USB to RS232 chip, it is true USB. The RS232 JACK on the
tail is useless. mkII-CN use the same driver as the original one
from ATMEL. Please click to install the USB driver when installing
AVRStudio. After the installation of AVRstudio, plug the mkII-CN to
PC, it will be identified by the PC, and install driver
automatically.
