This generally indicates that the connection between the pico and the FPGA isn't good enough to run at the JTAG frequency chosen. I have had good luck with braiding additional ground wires with the JTAG signals.

thx.. it started working properly, it's possible that there was a problem with the connecting cables... best regards
