| stephe | agg: all the signals seem fine, cdone goes high to confirm it’s programmed but then I don’t get any response from it, wondering if I need to do anything else to get it to start up after programming | 04:50 |
|---|---|---|
| stephe | Also is it possible to program the nvcm as spi slave if I send the nvcm file as bitstream? | 04:55 |

| agg | stephe: hmm, if cdone is going high i would expect the bitstream to be operational - i guess you've read the config doc so are doing the reset with cs low, 8 dummy clocks with cs high, assert cs, send bitstream, deassert cs, 128 more dummy clocks dance... are you sure the bitstream is correct? | 12:34 |
| agg | I haven't tried nvcm programming | 12:35 |
| tnt | stephe: make sure you're not skipping some of the dummy cycles and they're sent with th eother signals as they should. Else the IOs might not get released to the userbitstream. | 12:35 |
| stephe | Hmm I’ll check but I think I send them thanks guys | 13:27 |
| stephe | What dev boards do you guys prefer? | 13:29 |
