# Upgrade problem

## Question

Asked by logistica888 on 2015-11-12 in Serial-to-Ethernet & ConfigTool.

I have a WIZ550S2E-232
I would update the firmware using *.hex file
I’m using this procedure:
[github.com/Wiznet/WIZ550S2E](https://github.com/Wiznet/WIZ550S2E)
I found the *.hex files here:
[wizwiki.net/wiki/doku.php?id=pro … e_download](http://wizwiki.net/wiki/doku.php?id=products:wiz550s2e:wiz550s2e_download)
I try to upgrade to ver.1.0.1

I download first the WIZ550S2E_Boot.hex file
Then I download the WIZ550S2E_App.hex file
“Flash Magic” verifies ok both programs

When I restart the board I think start only the Boot program, not the Application program
The status LEDs on the base board flash alternately
The WIZnet_Configuration_Tool shows “BootLoader 1.0.1” in the “Firmware Version” box

Where is my problem?

Thanks

Hi

I used the instruction of picture number 2
The big difference is that in your “binary_v1.0.1.zip” file in the link:
[wizwiki.net/wiki/doku.php?id=pro … e_download](http://wizwiki.net/wiki/doku.php?id=products:wiz550s2e:wiz550s2e_download)
I can find these files:
WIZ550S2E_App.bin
WIZ550S2E_App.hex
WIZ550S2E_Boot.hex
I have not a single “boot+app.hex” file, like the picture 2

First test: I try to download first WIZ550S2E_Boot.hex then WIZ550S2E_App.hex
Second test: I try to download first WIZ550S2E_App.hex then WIZ550S2E_Boot.hex
Flash Magic is happy in both cases, it finishes the download, and it verifies files
But the effect is always the same:
-The status LEDs on the base board flash alternately
-The WIZnet_Configuration_Tool shows “BootLoader 1.0.1” in the “Firmware Version” box

No change
The Application doesn’t start
The problem is not solved

Thank you

Hi

Maybe I understand the problem
At the beginning I failed a TFTP update
In the eeprom the flag that enable TFTP upgrade is active

I upgrade correctly boot an app code with FlasMagic
When start the boot program is looking a TFTP upgrade
If there is not, boot has a TFTP_FAIL, and the app can’t start.
To start the app, I must clean the eeprom

Now should be fine

Thank you
