I`m having some problems with customizing bit file to configure my mesa(clone) board. Previously I used effinity software but it seems that chineese boards running on xilinx base. Unfortunatelly I can`t download xilinx software. Could somebody help me with compiling custom bit? Pinout attached below in custom vhd file

I can make a (7I92) bitfile but are you sure 7I92 bitfiles will work on that card?

99%. Allready flashed it with original 7i92 bit file downloaded from mesa store support zip files. File attached was modified from that zip also.

Amazing support Peter, but I really don't understand the expectation of the original post. 

Your Mesa cards are very resonably priced. You have obviously put years of work into designing and updating these cards, and provide outstanding support to us here in the forum.

Someone reverse engineers your work, floods the market with knock-offs, undercuts your livelyhood, and then expects support?

You are a better person than me Peter. In your place, I would be tweaking Mesaflash to brick any knock off which gets connected to it :)
Cheers,
Mark

Note that you can download the latest Spartan6 compatible version of the Xilinx tools
(ISE Webpack 14.7) for free but you do need to register.

Thank you for help. Everything works just fine. Xilinx was a bit tricky to download due to american regulations and policies. Somehow registration form doesn`t work correct. But finally I downloaded it today so this is first and last case.

Talking about original mesa cards, in my country it is almost impossible to get desired board on time. They simply out of stock. So I had to save 15$... I`m sorry.

Xilinx itself appeared an old nightmare for me to install. Heavy virtual machine, only Win7 32bit and 30-year old interface... I would not recommend customizing chineese boards after this experience.

P.S.: hope people who don`t help use Windows :)

Xilinx Webpack 14.7 runs fine on current Linux versions, no need to bother with Windows at all...
