In our teaching lab we have a mix of older and newer DE1 boards, which we have discovered have different versions of the Spansion Flash chip.

Can anyone help me understand what these errors mean and how to fix/avoid them? I am trying to get my code o compile, which it has been doing fine all morning, but now I am consistently getting stack failures as detailed below.

I am also driving a simple counter off the 192.0MHz clk that will toggle an LED at 250ms. Locked - pll_locked, going to a board LED This results in a core module with 4 I/O: The advanced parameters tab indicates a PLL output VCO frequency of 384.0MHz that will be divided down by 2 to my desired 192.0MHz clock.

Resulting output clock frequency = 192.0 MHz The ALTERA_PLL megawizard is used to generate the v14.0 PLL IP core. The 2.5V is driven by an LDO regulator with a 5V input.Ī 48MHz 3.3V 50ppm XO oscillator is used as the only clock to the FPGA - it drives FPGA pin CLK2P. The analog PLL power supply pins (6 VCCA_FPLL pins) have a common 2.5V rail, decoupled with approx.
