Just received the AMB82 mini today.  
initially I was receiving a compile error, but solved this by updating the board url in the Arduino IDE to

[https://github.com/ambiot/ambpro2\_arduino/raw/dev/Arduino\_package/package\_realtek\_amebapro2\_early\_index.json](https://github.com/ambiot/ambpro2_arduino/raw/dev/Arduino_package/package_realtek_amebapro2_early_index.json)

Now the blink program compiles fine but when it goes to upload I get the following

> Enter flash Model  
> Start uploading flash  
> Uploading. End Upload Flash.

From the examples I have seen there should be multiple dots after ‘uploading’ and a ‘upload success’ message (I am not getting these).  
After Resetting the board, the program has not uploaded. I tried the tools option to erase before the upload, this too did nothing. The original program is still intact.  
Any idea about what I am missing ? Is the board defective ?

Hi @alveron,

This is not usual. Can you check with different SDK version?

Thank you.

Further update, I installed the Arduino IDE on two other machines, both of these were able to program the device, so it looks like it is due to the configuration of my main machine that is causing the problem. I thought it might be that on my main machine I installed the IDE for any user and the ones that worked I installed just for my use. So I tried re-installing the IDE without any success, although I will probably need to do try this again as the new IDE seemed to pickup a lot of the old settings and so may have picked up any bad settings as well.
