15 years agoCyclone III stuck at POR?
Hi, I have problems to get a custom board work, the FPGA seems to be stuck in POR. It's a PCIe card with a EP3C10F256C7N. I attached an excerpt of the schematic to this post. I have 10 pro...

15 years ago --- Quote Start --- I shortened nCE to GND, but nSTATUS is still LOW. I understand that a faulty nCE can inhibit configuring the device. But can it really hold the device in POR and inhibit JTAG? --- Quote End --- I don't know. I don't have time right now to look again in detail at your configuration circuit. However, if you wanted to, compare it to this stratix ii design, see p51: http://www.ovro.caltech.edu/~dwh/carma_board/gda06rb004_carma_v0.87_dec03.pdf Perhaps a difference will stand out to you.
