New ContributorCyclone 3 Not entering AS Mode
Before i start, will love to say am new to FPGA and entry level with Electrical.
We have an old tool we purchase that has a Cyclone 3 board on it. We have a simple code (attached) that we can easily run through JTAG with no issue.
When we try to run as AS we get some error about invalid device. We load the code to the EPCQ16A memory chip using a tool and when we put it back, it still not running. We probed the DCLK of the Cyclone and signal is at 17khz and very noisy.
Spent weeks on this with zero support. Please can someone tell us what we are missing here?

Without knowing the hardware setup of the board (is it a dev kit or custom?) or seeing the original project (this is just a programming file you've attached instead of the Quartus project), it's going to be difficult for anybody to help you out. If it's a dev kit, mention which one it is. If it's custom, provide schematics to see the connection and setup between the device and the flash.
