if it is possible for the caravel core to at least load code to blink the LED (as implied by the video above), is it possible to talk to user-projects over wishbone or is that part not working either?

that might be possible, but configuring any user IO has been a challenge.

ah. just wondering if it would at least be possible to salvage some part of the user projects which can be tested solely over wishbone

A couple of the wishbone bus signals were among the hold violations (mprj_sel_o and mprj_cyc_o), but I don't know how or if they would affect communication with the user project. I didn't see any of the logic analyzer signals in the hold violation report.

😓

I will test wishbone access when I get a chance to, as well as the logic analyzer, to see what capabilities can be salvaged.

thanks. is there a copy of the violation report file for the mpw-one caravel available or would I have to run the timing analysis tools myself?

@Manar Abdelatty has violation reports (Manar, can you post the report for MPW-one to the #mpw-one-silicon channel, please?).

@Anish Here is the violation report for mpw-one at the typical corner
