the fw sizes above may need further adjustment, but those values are good enough for now

as a quick fix you can safely remove those tee commands from easyddup.sh, they're for logging purpose.

The BURNIT variable just makes the utility go through the motions of burning and noburn skips the lowlevel firmware writing and the reboot. So with the -n option, YES we want to go through the motions but we don't want to actually burn. Those features were written at different times so granted less confusing variable names could have been chosen.

Does your build have which? (try "which which") I was thinking of using 'which tee' to see if tee is available.

your fw download speed is already fast, but you can try EDDUP_USE_MULTIPART=8 to see if it can be even faster.

what's the output of "type tee"?
Entware has coreutils-tee.

In your reply you wrote that it should be EDDUP_HARDWARE_FOLDER, which apparently is a typo.

On my router:

Code:

root@DD-WRT:~# type tee
tee: not found

In debian:
$ type tee
tee is /usr/bin/tee

But for just checking for its existence, you can do something like:
if type tee >/dev/null 2>&1; then (stuff); fi
or put it in a function istelf

you need both lines for auto-select to fully work on your router:
EDDUP_AUTO_SELECT_FILE='tplink_archer-c7-v2-US.bin'
EDDUP_HARDWARE_FOLDER="tplink_archer-c7-v2"

Seems to be all working now, aside from not having tee but that's not a biggie.

I'll look at the scripts closer sometime to see if I can add further automation, like how DD_BOARD can give you most of the information that's used in both of those variables.

I see that you're running easyddup from /tmp/ folder. Just a reminder: that folder is on RAM and will be cleared on every reboot.
for your case, EDDUP_USE_MULTIPART=8 seems to be slower than tradtional curl, so it's better to remove/comment that line from your easyddup.ini
for fully automated operation, you can add/uncomment the following options in easyddup.ini:
Code:

EDDUP_ERASE_NVRAM=N
EDDUP_SAVE_SETTINGS=N
EDDUP_AUTO_CONFIRM=Y
EDDUP_AUTO_SELECT_LATEST=Y
Note that when EDDUP_AUTO_SELECT_LATEST=Y, the script will terminate if the current fw is already the latest version.
can you share the output of
Code:

nvram show | grep -i board
If there's some additional board info in nvram then yoyoma2 can use that to auto select the fw folder/image file.
Is there any other automation you have in mind? it may be already done/partially done by some of us, or yoyoma2 may decide to expand his easyddup script if the idea is good.
For me, I have a call-back script to do the following tasks:
- Backup full nvram to bin file (@yoyoma2 sorry I'm lazy to figure out which variables to add to nvram-dd-wrt.ini)
- Update/upgrade Entware packages
- Write a report file so that I can copy/paste to the "new build" topic. The report file is sent to my email address after reboot.
- Remove old downloaded fw files, only keep the latest 3 versions, so that the USB disk won't get full. @yoyoma2 do you think it's good to add this option to easyddup.sh?

I'm not a script person so thanks for the tip. Will use type...

@IONK I like your idea of limiting the cache entries to save USB drive space. Do you have some working lines of code to share?

Code:

# only keep the last 3 FW folders
find "$EASYDDUPDIR/fwcache/" -type d | sort | head -n -6 | tail -n +2 | xargs -r rm -r

not refined but at least it's working for me
