Hi,

You may have the same problem as this topic viewtopic.php?f=16&t=977&p=3400#p3400

If your flash size is 512KB, AT_v0.40 can only work well without OTA:
eagle.flash.bin 0x00000
eagle.irom0text.bin 0x40000
blank.bin 0x3e000 & 0x7e000

If your problem is still unsolved, please provide the capture picture of your flash download tool while downloading.
