I am using a 4MB NOR with ESP8266(ESP-12E), I can downlaod and flash into the 1MB+4KB region(option 6), and checksum is okay;

after download and do checksum, I called

then I got this failure
pcode=04x, frame_type=Fatal exception (28):

and system reboot again back to the first copy which is at 0+4KB region---

I compared these two files, they are exactly the same , matching on each byte; I am curious, should these two file be different? because they are linked to different place, isn't it?,

I choose 1 on step 2 and 6 on last step to build BIN1
I choose 2 on step 2 and 6 on last step to build BIN2

I can't think of a reason why the bin2 image does not boot, any hints?
