CC3120: User file -- page not found

Hi there,

I try to play with CC3120 on my custom board. So far, I can program serial flash through embedded programming. I have programmed the image created by UniFlash with servicepack "sp_3.16.0.1_2.0.0.0_2.2.0.7.bin". In UniFlash, I choose AP mode and most of the default settings. After power on, I can browse the default homepage of CC3120. I can play with it with no problem, for example, sync date time and ping.

Then, I tried to add a user file "/user/index1.html" and re-program the image. This is a simple hello-world page. After power on, I can still browse the default home. But, when I type url "10.123.45.1/user/index1.htm" in browser, it shows "404 - Sorry page not found".

Am I missing something?
