Hello,

I've a board with XC3S700AN-FGG484. I tried to compile T51 mcu for it (T8052). The design is very simple, the global clock is divided by 4, there is a switch for reset and one for clock enable.

I use WebPACK 10.1.03 (Linux) App. version K.39.

Everything goes right, bit file is gnerated.

However, if I assign pins for RXD and TXD, during implementing design, I get an error at mapping stage:

ERROR:Pack:2310 - Too many comps of type "SLICEL" found to fit this device.

Is it really due to the 2 pins?

Thank,
