STM32-MMDVM_HS... not working

[DS1SKU]

Hi,

I live in Seoul, South Korea.

I buy Mmdvm from chinese seller.

But... I am begginer, so, I don't know how to config...

Seller page explain...

wifi: 802.11b/g/n
quad core a7 1.2 ghz
512 mb ddr3 ram
16 gb tf
Installed Raspberry Pi Zero W

But, I can't log on that hospot, so I can't conpig D-STAR.

MY rig is ICOM ID-51E

So, I think. Installed Raspberry Pi Zero W is incorrect? so, I delete Raspberry Pi Zero W, and download newst version at pi-star site.

Hmmm... oooops!

Now, Mmdvm is not working, perfectly.
I can't siwtch on Mmdvm, even.

Help!!!
