Всем привет! Осваиваю ПЛИС. Чип XC6SLX9-3TQG144C, SPI флеш память AT45DB041D.
Среда Xilinx ISE Design Suite 13.4, программирую IMPACT -ом
В саму плисину все прекрасно загружается и прошивка работает. При попытке запрограммировать флеш память

Сбой программирования.
При этом флешка стирается и проверяется командой Blank Chek без ошибок.
Вся схемотехника подключения флешки к плисине вроде сделана по Spartan-6 FPGA Configuration User Guide, только DONE не подтянут к Vcc, а висит на этом выводе светодиод с резистором на землю.
Подскажите что я делаю не так, заранее спасибо.
