altera_onchip_flash

The submodule "altera_onchip_flash_avmm_data_controller" in this IP has some problem. WRITE_STATE, this FSM will unexpectedly been hold when I continues write data to flash. It will cause status...

i replace all (write_count != 0) to (write_count > 0) in the WRITE_STATE FSM

WRITE_STATE_WRITE: begin

if (write_count > 0) begin//(write_count != 0) begin

write_drclk_en <= 1;

write_count <= write_count - 16'd1;

end

else begin

enable_drclk_neg_pos_write_reg <= 1;

write_drclk_en <= 0;

write_count <= FLASH_BUSY_TIMEOUT_CYCLE_MAX_INDEX[15:0];

write_state <= WRITE_STATE_WAIT_BUSY;

end

end
