SPWF01SA file system problem

Hello,

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:2:Reset

+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&sharpN nv_seDi:l = valu4♯: nv_wiHiemacaddr = 00a80:E1:B9p7 :2B♯ totf_mode = o♯  blink_lsd = 0♯  wind_off_lowm= 0x000000a0♯ lwindlof_medium= 0x00000000♯wind_o+f_high = 0x00000000♯  user_descW=IanonymouN5D:54:54:6::63:74:00::0:00:00:00:00:00:00:00:00:00:00:00:00:00:00:0W:00:00:00:a0:00:00:00:0t:00chdog 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.

Best regards,

Rok Tav?ar

There are no limitation into SPWF01 FS update, or FW update.

Seems external host, managed by STM32CubeExpansion_WIFI1 package, goes crazy when using that command. I suggest to:

- download latest available STM32CubeExpansion_WIFI1_V3.0.2

- use basic VCOM application to bring SPWF01 back to life again. Run an AT&F to just move all variables to factory value.

Hello,

Thanks for trying to help but this is not working. I assume that by external host you meant NUCLEO-L476RG, which is only running serial passthrought at the moment. I did what you suggested anyway (AT&F returned OK) with similar results, some AT commands seem to work properly, but most returned garbled text output, as shown, and SPWF01SA still doesn't work.
