Cyclone 10 GX Development Kit ddr problem

Hi dlim,

Invoice and serial number send by message.

1. This board is for cyclone 10 gx evaluation, not for product.
2. This is my current jumper setting and document default.
3. This is my current clock setting.
4. No, In my first time use bts to test this board, it show failed.
5. This is some code.

ed_synth u0_ed_synth (

.reset_reset_n (fpga_resetn ), // reset.reset_n

.clk_50_clk (c10_clk50m ), // clk_50.clk

.global_reset_reset_n (user_pb[2] ), // global_reset.reset_n

.master_driver_msgdma_0_status_mon_export (test_status[1]) // master_driver_msgdma_0_status_mon.export

);

// USER LED: High ON

assign user_led[0] = !test_status[0]; // error_mon: high - error happens; low - error free

assign user_led[1] = test_status[1]; // status_mon: high - normal status; low - time out

assign user_led[2] = heart_beat_cnt[26]; // heart beat

assign user_led[3] = heart_beat_cnt[26]; // heart beat

as you can see user_led[0] is always on. so i think error happens.

6. lowering down DDR3 operating frequency from 933MHz to 800MHz get the same erro.

Thanks for your help.
