Programming NiteFury with fallback to factory set design #30

Closed mayureshw closed 1 year ago

mayureshw commented 1 year ago

I have a NiteFury decvice. I do not have a JTAG cable. So do not want to land into a situation where NiteFury is `bricked'.

Is there any way to leave the factory design untouched or any way to recover it if overwritten (without a JTAG cable)?

I have another board - Digilent Arty - where I transfer bitstream to the device over a Microusb cable. I think it doesn't flash the device as I can always reboot to the factory set design. Can I use NiteFury in this way to always restore it into factory reset state?

I think there is no option but to buy JTAG cable.

It looks a bit costly. Is this a passive cable i.e. just wires or it contains any circuit? I wonder if I can get it made from a vendor who creates custom cables.

Alright, looks like it's best to buy the Digilent HS3, despite its costs.
