Hello Illuwatar, be sure that you order the correct sram.
You need these sram version: ISSI IS61LV51216-10TLI or you
can order also srams from cypress CY7C1051DV33-10ZSXI.

The srams  IS61WV51216-10TLI are not working correct with the minimig core.

Yes, thats true, I was having the same problem.
I was talking with Yacube about the problem with the srams.
He is using the ISSI IS61LV51216-10TLI.
Normaly the other srams from ISSI should work, but I think the
problem is that the minimg is designed for 3,3V srams, so the srams ISSI IS61WV51216-10TLI are 8ns "fast".

You can order ISSI srams from mouser.com

I have ordered some samples from Cypress directly on the site from Cypress CY7C1051DV33-10ZSXI.

Hi Illuwatar,
you should contact yacube first again. Maybe
he can modify the core a little bit so that also the WV version will work.

Yes the timing could be the problem.
The core was booting, but the Kickstart screen does not appear.
With Kickstart 2.0 I was seeing the screen but after that
the board hangs or a Guru meditation was displayed.
