netgear GSM7352s byte error crc check firmware

Hello,


I have a netgear GSM7352s (v1) giving me every time with every firmware versions an netgear "1byte error crc" after uploading the firmware throug Xmodem (extra putty).

 

http://kb.netgear.com/app/answers/detail/a_id/21

 

I tried this KB, but the command "dev osapiFsUtils" do nothing.

Hi IT_VBO,

 

Welcome to the community. 

 

I suggest that you contact NETGEAR Support for assistance.  Be reminded that a support contract might be offered to you if ever the support warranty has expired on the GSM7352S.

Hello,

 

The warranty is clearly out. But i thinking "the Community" space can helping me to delete the "corrupted files" for doing an successfully the firmware upgrade. Like the KB12803.

Re: netgear GSM7352s byte error crc check firmware

You likely have bad flash since the CRC error can also happen if you have bad flash that can't be written correclty to.

 

First you need to check what firmware you do have on the switch.  There is usually an option in boot menu for operation code status.  May want to check that and post back what firmware version you have on there first.

 

Second, the dev OsapiFsUtils command will only work once you are at the enable prompt.

 

that article is basically to free up space on the flash.  You can always flash the backup image to work around that.  Make sure you don't try to upgrade to 10.x code since the v1 don't have ability to load that code up.  (too old of hardware).  Use 8.0.3.x

Hi IT_VBO,

 

As a follow-up to Jedi_Exile's response unto you, make sure to upgrade the firmware via TFTP.  Its because HTTP might give CRC errors.  Here is the link where to download the latest firmware as well as the list of firmwares for the GSM7352Sv1 (v = version).

 

Were you able to execute the command "dev osapiFsUtils" via the enable prompt then proceed with it?

Hello,

 

I tried with theses Firmwares :

gsm73xxs-5.1.1.3.stk

gsm73xxs_6_0_0_15.stk

gsm73xxSv2-8.0.3.34.stk

gsm73xxSh2_8.0.3.49.stk

Everytime "ERROR: Code image size of 1 bytes is invalid."

 

I cannot load Operational Code "ERROR: Operational code CRC is not valid, you must load new code."

I deleted them with the menu, but same. ( i tried different speed's and different USB to RS232 adapter)

 

The Puty Connection :

 

Options available
1 - Start operational code
2 - Change baud rate
3 - Retrieve event log using XMODEM
4 - Load new operational code using XMODEM
5 - Display operational code vital product data
6 - Update boot code
7 - Delete operational code
8 - Reset the system
9 - Restore configuration to factory defaults (delete config files)
[Boot Menu] 1

Hello,

 

I am connected through the RS232 Consol port with Extra putty for terminal (extra putty permit to send Xmodem files). I try to execut the dev command where i have the boot menu.

 

I am sure i have an Hardware V1 (GSM7352Sv1 serial numbers start with 18J, 1J9.)

Re: netgear GSM7352s byte error crc check firmware

Hello,


On KB http://kb.netgear.com/app/answers/detail/a_id/22

"For GSM73xxS, instead of using the firmware images available on the NETGEAR support site, first obtain the file “gsm73xs-6.2.0.6.opr” available from URL ftp://downloads.netgear.com/files/gsm73xxs-6.2.0.6.opr. Then, use the following procedure to load the switch with that file. After reboot the switch, upgrade to the 6.3.x.x firmware normally using either TFTP or HTTP from WEB interface, or copy command from CLI. The file “gsm73xxs-6.2.0.6.opr” should only be used for loading the switch using XMODEM and serial console. Do NOT use the file for normal firmware upgrade using TFTP."

 

Where i can get the “gsm73xxs-6.2.0.6.opr” file please ?

 

Maybe this is the solution...
