Two things to check/do to make the 16-bit counter project work for the AVANT Evaluation board:
1. The 16-bit counter project does not have port assignments on the PDC file for the AVANT Evaluation board. User need to assign the reset_n port of the design to the push button switch of the board, the clk port of the design to the onboard 12 MHz oscillator, and the c output ports of the design to the LEDs of the board.
2. On the AVANT Evaluation board, user need to do the following:
2.1. To use the oscillator, you need to set the jumper JP65 to 2-3 and close jumper JP6,
2.2. To program the SRAM directly, user need to set the jumper JP25 to 1-2.
Refer to the board user guide on this Lattice web page for more details on why user need to set these jumpers:

For the Programmer error, we could workaround this issue by first programming with JP6 open (or with JP65 open or set to 1-2). Then after a successful operation in Programmer and the Done LED lighting up, then we can put then close JP6 and/or put JP65 back to 2-3 to connect the on-board oscillator to the FPGA to start the Counter LEDs blinking.
