SPWF01SA firmware update

After firmware update, module does not working.

I was using a cople firmware versions:

-- SPWF01S-140512-703c969-RELEASE-main.bin

-- SPWF01S-140805-3f58d6b-RELEASE-main.bin

each one is does not working.

As start address I used 0x8008200.

After couple tests I decided to read hex flash data from the second Wi-Fi module and write it to the old one. As result - > The old one is working.

On the next step I was using STM32 ST-LINK Utility for the flash programing, start from the 0x8008200 address. But module is still does not working...

Could somebody explain me what I am doing wrong?

If I trying to use OTA for the FW upgrading, I see:

''F/W update model 'SPWF' not matching local 'SPWF01SA'

===

Ok... How should I understand this? Does it mean that my WiFi module is different from the SPWF01SA?

Hi Artem,

could you please share the content of AT&V command?

A couple of questions:

- which FW version is the working one?

- which FW version was inside the module, before any update?

- what does it happens when a not working FW run? UART, LEDs, etc...

Sorry for this.

I guess, the firmware version for the working module is: 1203-121218_01-30-gf756599-stm_demo

After ''upgrading'' I don't see any blinking on the leds side (leds are OFF) and no answer from the UART.

Hi Artem,

I try to figure out what's happening.

&You are moving from a 2012 release (the oldest). There is a big big difference from latest releases to that one: usage of low speed external oscillator. After upgrading you should see no LED blinking, and no activity over UART, This ''bad but know'' behavior should stop with a simple power off/on of the module. There is a sort of inner fine-tuning inside the module, needed to be performed on the very first power on of the module after upgrade.

This is a one-shot process. Once in a module's lifetime.

I assume:

- you already powered off (and on again) the module after update from 2012 release?

- 0x8008200 is wrong. 0x8002800 is the right one. It was a typo, wasn't it?

Thanks for details.

Sorry but I'm really far from offices, and I can not test your issue.

Thanks indeed!

As usual, simple solution which need to be know :)

After upgrading, power OFF-ON and some time waiting -- helped me.

IÂ´m having the same problem, but after power off/on, there is no uart response and no blinking LEDÂ´s.

Using Flash Loader and FW_update (prompt) I can write any version without error.

Can I ''bricked'' my module anyhow?

Gerardo GALLUCCI · ‎2015-02-23

Hi Daniel,

I need some info:

- which Flash Loader (ST software) version did you use? Please note that, if you specified a wrong starting address (different from 0x08002800), module is ''broken''. You'll need to contact your local ST support, and ask for a ''full image''.

- which ''original'' FW version?

- which ''target'' FW version?

I'll try to replicate your issue.

Thanks

jerry

ps: blink led is, by default, disabled. Check WiFi led (or UART) to be sure that module is alive.

I solved my problem!

I got another module and copied all the flash content using FlashLoader.

Then I used this ''full'' file and, again using FlashLoader, rewrite all flash memory, starting on 0x8000000 address.

After this, I had uart communication again. But in an old version.

I only could update to a new version using OTA update.

It's fine for SPWF01Sx.1y

Do not repeat these steps using a module without integrated external flash (SPWF01Sx.2y). All production data (MAC address, for example) are lost.
