RBR750 TFTP issue
Looking for some assistance here. Got an RBR750 which is provided by the ISP. The Contract is over and I am trying to flash it to generic firmware. I have done it previously for RBR50 without any is...
You are absolutely right. Surely the tftp is working as nmrpflash appears to be sending the file and while it happens, the router has red light. This means, like you said, the timing needs to be right if one is trying to do it manually. nmrpflash identifies the correct timing and sends the file. I'll give the manual a go but without the switch, it is really fiddly. Thanks for your help though.
Try NMRPFlash then, as it's supposed to figure out the timing for you and send the file soon as it detects TFTP is up and running.
That is the issue. I have tried that but get an error message "TFTP block rollover. Upload might fail!" and upload doesnt work (Upload file is more than 40MB and I think limit is 32MB)
Interesting. Have not seen that.
Well one method i've done is to have a command line box open and do a contant PING of the 192.168.1.1 address. After you reset the RBR, the ping will give no responce results, keep watching and when the ping changes to getting a response from 192.168.1.1, thats when TFTP should be up and running, send the FW file using the TFTP client PUT command with the FW file.
