SPWF01SA file system problem

I use SPWF01SA on IDW01M1 board with stm32l476rg. This setup worked correctly until I updated static httpd filesystem via at+s.httpdfsupdate. File system image has a lot of small files (562), but with total size 77 KB. Few previous updates with fewer files worked correctly. After update was finished successfully I reset with at+cfun=1. After this, SPWF01SA stopped to work correctly. When I power it up or reset I get:



+WIND:1:Poweron (160129-c5bf5ce-SPWF01S)

+WIND:13:STM SPWF01SA11 IWM: Copyright (c) 2012-2015 STMicroelectronics, Inc.  All rights Reserved.

+WIND:3:Watchdog Running

+WIND:0:Console active


If I try some other at commands I get garbled outputs, for example at&v:


# Dumping All Configuration Keys:

#  nv_m
nuf = STM
#+ nv_modeW I SPWF01SA11
#N nv_seDi:l = valu4
#: nv_wiHiemacaddr = 00a80:E1:B9p7 :2B
# totf_mode = o
#  blink_lsd = 0
#  wind_off_lowm= 0x000000a0
# lwindlo
= 0x00000000
wind_o+f_high = 0x00000000
#  user_descW=IanonymouN
chdog Terminating, reset pending


i tried fw update but get error:

ERROR: Wait for Hardware Starting


I get same error if I try to update file system again.


Is it possible to bring SPWF01SA back to working condition or not?

And what are limitation of file system.
