hello:
       I choose TE0841_40_1C V2.0,FPGA cannot boot from flash.in addition，A calibration failure occurs at DDR4 MIG IP.How to solve these two problems？

JH:
Hi,
which TE0841 assembly version did you bough? Can you send me whole article name or serial number (small number with QR code on the module)?
Depending on assembly variant you need different settings and also additional constrains files.
We have some reference designs with prebuilt binaries:

https://wiki.trenz-electronic.de/display/PD/TE0841+Test+Board#TE0841TestBoard-Download
Can you test them? In case your variant in not included until now, send me the hole article name or serial number and I tell you which one you must select.

hi,
  The version is TE0841-02-040-1I, flash selected in vivado(2018.3)is MT25QU512A,DDR4 chips are K4A8G165WB-BIRC.The  .bit file included in Reference_Design（2019.2） work successfully in DDR4 test.The .mcs included in Reference_Design shows that the loading is successful, but it can't boot from flash.

So DDR problem is solved

Vivado say it's still not programmed also when you power off and on and reconnect Vivado HW Manager?
Or mean you did mean with "can't boot", you did not see any output on uart or so?

Which carrier did you use? Which external power supply? Some current limit? Do you use Heatsink for the module?

No,it just Microblaze step passed,and calibration failed in first DQS step with my bit file.

yes

If fpga programmed,led in board chang light to dark and status register show flash initialization not complete

carrier is TEBA0841-02;Heatsink is using；Programmed with JTAG,FPGA work normally.
