I’m presently stuck in an upgrade cycle of a 4036. Image 2.1 at the moment and 3.0 is failing due the lack of media space. The manual do not specify any way of displaying flash, ram or whatever media the image is stored on. There are no CF card inside, from what I have seen. delete, format or any other command of media seem to be missing as well.
no point of upgrading firmware alone. Nothing stored in the location you indicate. I image it’s text files at that location anyways, like on Cisco. Virtually takes up no space at all. Firmware errors like before as nothing has changed.
Is there a procedure for complete flash of disk and restore from TFTPBOOT? Does anyone know the syntax to TFTPBOOT? Works well on Cisco. Here manual specifies no instruction for the commands in U-Boot, that I have seen.
Thanks, I took that to mean FTP server. I know the TFTP process is manual, why I asked for the syntax to point the TFTPBOOT to the TFTP server. I have tried everything I can think of regarding the syntax in the U-Boot. I’m very familiar with this from Cisco, however have no clue about eh syntax. Question mark gives no hints and manual states nothing.
Could you be so kind to clarify, where to link these symbolic files? I guess, basically we need to know where the file should go. We only find traces of upgrade files pertaining to firmware upgrades.
Deleting the /dev/nul only freed 1,7mb, so no luck there.
Thank you for your help in the matter. The U-Boot, do not contain the build_flash command unfortunately. The best I could find there was the tftpboot, however I could not figure out the correct syntax. Manual and help menu don’t mention ether.
Yes, I have console cable and I figured the 38400 speed out myself, so +1 there.
When I was using build_all_flash batch command my 4036 switch’s firmware version was 3.9.1.
Because I was experienced abnormal boot process and finally I was clear that situation via this command.
You said previously below…

As the text you just quoted, we have image 2.1 and try to upgrade to 3.0. I’m aware of the above steps that you outline, but since the available space is inadequate (above image) for where it inflates the tar file, this is where I get the error message from the (first image). Obviously since it cant inflate the packages, it is a corrupt file. You can see why this is an issue, as the image we upgrade to is 97M in size and the presumed disk location only is 100M. Inflation then isn’t possible. Had it used the 256M partition, it would have been flying. Update firmware Chassis, gives me no control over the location, to place the files. It has its own logic.
The syntax was wrong and I never figured it out. I have a Master degree in networking, but thanks for your advice in having IP addresses on both ends of the layer 2 link….
I solved the problem with a workaround in Linux. Only from 2.1 it was a problem. Rest was just the normal procedure.
tftpboot server ip 10.0.21.15 ? Don’t work… can you check your syntax?
tftpboot server ip 10.0.21.15 comes close, but dont start transfer but gives this output: tftpboot- boot image via network using TFTP protocol… then what?
