ok thanks,
but compiling openwrt didn't provide initramfs image, how to build it then?
pretty sure it's an option in menuconfig ....
hi boss,
well i managed to compile an initramfs file renamed vmlinuz and put in tftp directory.
the problem is that something's missing:
TFTP server address is 192.168.0.100; our address is 192.168.0.254
Get filename 'vmlinuz'.

Doesn't look like the image you just created .... ---^
you can't autoboot an initramfs sent over TFTP.
need to load it, then start it manually using with bootm, if I remember correctly.
thank you @frolic for your help
maybe you are talking about Uboot. this unit (cpe510v1.1) uses SafeLoader boot.
and i was able to autoboot an initramfs image downloaded elsewhere but at the end of boot keps restarting.
yeah, bootm's uboot ....
what happens if you try to boot the openwrt initramfs ?
i had to rename it vmlinuz in order to tftp to load it
that's however still not the home made openwrt image, unless you didn't clone the official repo.
i did this:
git clone "https://github.com/openwrt/openwrt.git" first then selected my target in menuconfig
that looks correct, but in that case it isn't booting the initramfs after all.
is that for snapshot?
i wonder if it's possible to clone an older version like BB or CC or Lede...and how
try https://github.com/openwrt/openwrt/releases can't verify it myself, corp firewall/proxy will try to DL and verify the file 1st

hi again boss,
well i tried many files but none of them worked.
i feel deceived
Older versions are part of the same source.
download sources again in a new folder
git clone "https://github.com/openwrt/openwrt.git"
git checkout TAB-Key TAB-key
will show the list of available old version branches.
FETCH_HEAD origin/openwrt-21.02 v18.06.0-rc1 v19.07.0-rc2
HEAD reboot v18.06.0-rc2 v19.07.1
lede-17.01 v17.01.0 v18.06.1 v19.07.2
master v17.01.0-rc1 v18.06.2 v19.07.3
openwrt-18.06 v17.01.0-rc2 v18.06.3 v19.07.4
openwrt-19.07 v17.01.1 v18.06.4 v19.07.5
openwrt-21.02 v17.01.2 v18.06.5 v19.07.6
ORIG_HEAD v17.01.3 v18.06.6 v19.07.7
origin/HEAD v17.01.4 v18.06.7 v21.02.0-rc1
origin/lede-17.01 v17.01.5 v18.06.8 v21.02.0-rc2
origin/master v17.01.6 v18.06.9 v21.02.0-rc3
origin/openwrt-18.06 v17.01.7 v19.07.0
origin/openwrt-19.07 v18.06.0 v19.07.0-rc1
select an old version with ONE of the following commands
git checkout openwrt-21.02
git checkout openwrt-19.07
git checkout openwrt-18.06
git checkout lede-17.01
If you need to try another old version, download sources again and use a different command to switch that to the old version you want.
In older releases this device is in ar71xx target, so if you do not find it in ath79 (or if there is no ath79 target at all), check in that target too.
This is the commit that added support to that device v1 https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=47ab1cbf23aef658f46bd86af88edb4e3f665639
it was done in 2014 so you should find this device in all the listed old versions.
hi mates,
tried compiling many versions but something's missing:
TFTP server address is 192.168.0.100; our address is 192.168.0.254
Get filename 'vmlinuz'.

then reboots
now it's booting a 4.4 kernel, but is it an initramfs, it seems kind of small ... ?
i have no clue .
if anybody has some files to offer i can try...
if recovery through tftp always failed, its cause the damage of partition table or product info. the only way to repair it is using dump file.
Please enybody can share with me a dumo file of tplink cpe510 v3.20, i trayed all but at last i need dump file. Please help me
