Recapture ARTY RISC-V?


Upon pressing PROG or RESET, my ARTY runs coremark and reports the results, BUT the SiFive ASCII-rendered logo does not appear; it just runs coremark again. The ARTY isn’t seen from within Freedom Studio (using JTAG/Olimex).

Can anyone suggest how to regain control of the ARTY with the Olimex-USB-Tiny-H and Freedom Studio (or freedom-e-sdk or J-LINK) so I can re-flash it?

Many thx.
