TFTP Retry count exceeded; starting again

Installing and Using OpenWrt
1

When I trying to download openwrt using tftp by : tftpboot 0x8100openwrt-21.02.0-lantiq-xrx200-tplink_tdw8970-squashfs-sysupgrade.bin

I faced this problem : retry count exceeded; starting again

Please can any one help me.

same problem brother not solved.

is this exactly the command line you used ?
is the file name really 0x8100openwrt-21.02.0-lantiq-xrx200-tplink_tdw8970-squashfs-sysupgrade.bin

Yes brother I used this command, and the filename correct.

10

are you installing openwrt, or upgrading ?

is the tftpd set up properly ?

11

My router has only one .bin file which it is upgrading one.

12

indeed, but the procedure is different if you're already running openwrt...

13

I only follow these instructions : https://openwrt.org/toh/tp-link/td-w8970_v1#serial

14

there's also https://openwrt.org/toh/tp-link/td-w8970_v1#luci_web_upgrade_process

depending on the current status of the device.

and if you followed the instructions for the serial installation, you're missing a space, in the tftpboot command :wink:

There is at least a space missing between the adress and the filename.

Last time when I saw that meessage I didn't plug in the Ethernet cable... Only checked that after trying whatever else and gradually starting to freak out :grin:
