Hi，在下完 uname 後呈現出來的訊息是 linux 沒錯 我在 toolchain/linux/asdk-6.4.1/linux/newlib/bin裡是有看到 arm-none-eabi-gcc ![image](https://us1.discourse-cdn.com/flex016/uploads/ameba/original/1X/e390f2140dbe99ee62ab425726fbfe9d865b3090.png) 會不會是script沒有把環境變數設好呢? 謝謝 ---

我刚在 Ubuntu 18 上 git clone 了 Github SDK， compile 时没出现这个问题。你在用哪个 branch? ---

Hi , I am very very new about this board. Here is my tools: 1.windows 10 2.using cygwin 3.sdk from github 4.

Dear wyy, Thanks for your quick reply ! Actually, I had tried this yesterday. So, I have to try to let my Win10 be able to run this setup-x86.exe first ? Thank you ! ![擷取](https://us1.discourse-cdn.com/flex016/uploads/ameba/original/2X/0/0631d356fc3c2b88c95acea85c794f8733c41e5c.png) ---

yes, you need 32-bit cygwin to compile the SDK ---

Dear wyy, I have no luck on running this setup-x86.exe on my windows . Any clue for me ? Also, I had a Mac mini. Should I try the following “Linux” on the Mac system ? Thansk! ![擷取](https://us1.discourse-cdn.com/flex016/uploads/ameba/original/2X/8/8cdf02f9427ec214526958859a2d23051cdb9c66.png) ---

can you provide more information on the system you are using? windows version, cpu, how old is it? the SDK works on Mac as well, you can give it a try. ---

Hi @Vic 不是电脑的问题，是 Cygwin 32-bit 在 11 月停止更新弃用了。安装的话，需要开 cmd 用 ```auto setup-x86.exe --allow-unsupported-windows --site http://ctm.crouchingtigerhiddenfruitbat.org/pub/cygwin/circa/2022/11/23/063457 ``` 这行指令才能跑。 ---

Dear wyy, Got it , thank you . **One more thing, if I could use both cygwin and iar for building the code. Which one would you recommand ? I think code/build performance sould be my main concerns.** Thank you! BR, Vic ---

It really depends on preference. From experience, Linux compiles the fastest. Cygwin and IAR should be roughly comparable. If you are familiar with the IAR editor, then go ahead and use IAR. If you wish to use another editor, then you should use it and compile with Cygwin. ---

One more quick question: Is SWD is the default ON after power-up ? I am trying to use IAR + Jlink on the SWD interface . Any hardware configuration must apply ? Cause I can run the “download active application”, and the message is ![reset](https://us1.discourse-cdn.com/flex016/uploads/ameba/original/2X/8/8dcc1126c006b85e257be5991e7e88cce27c4680.png) .

Dear WYY, On trying “Download active application”, I am still been blocked on this “reset error” message. ![resetErr](https://us1.discourse-cdn.com/flex016/uploads/ameba/original/2X/b/b0b7c0117c0d0221a5a0eea97e7f36ebb2be6b5f.png) Because I am using the MINI board, my swd wire connections are reference from [here](https://forum.amebaiot.com/t/tutorial-debugging-rtl8722-with-the-new-arduino-ide-2-0/656). here. ![IMG20221229123944](https://us1.discourse-cdn.com/flex016/uploads/ameba/original/2X/e/ea328528298e8040794359e94d6f7339b7542c54.jpeg) The same jlink can use on : “00010055-sdk-ameba-v4.0c” + IAR + JTAG interface. Any idea ? Thank you ! ---
