Add support to Unifi Switch - BCM53343

anon50098793 · March 26, 2021, 1:17pm

ok time to introduce a new tool...

sudo apt-get install -y binwalk

then

binwalk -e FILE.bin

if you have an OEM firmware file... use binwalk on it too...

NOTE:

thanks to the help from above... this exercise is likely just to get you 'tooled' a little better... but essentially.... based on the info they've given...

someone more capable can pretty easily build an initramfs for this without functional networking ( let me know if you still want one after a few weeks and nobody else has a recipe/file for you and i'll (try-to) do it )
next best move for you is to read up on this 'OpenNSL' business to see how much of a pain other people have found it...

Excelent. Will do as soon as I get back home. Need to take my mother-in-law to take the covid vaccine in a short while

anon50098793 · March 26, 2021, 1:30pm

there is one more possibility which is a bit 'left-field'....

you may be able to 'hexedit'/hack the firmware dump and change to correspinding 'bits' in the rom that return the POE driver init/status val to something which makes the OS happy ( disabled||fake-functional ) ( or if your a real hw modder... hook into the bus with a buspirate or something and 'mimick' the protocol )

it's pretty lowlevel ( probably beyond my abilities ) but given the amount of units with this issue... you could probably find more people on the general internet willing to help attempt this 'mod' ( or there is also a slim chance there is a 'property' elsewhere on the rom that governs POE init behavior... in this case it would be much easier to find and modify that senv/uboot-env? schmoo? noideawhatthatis nice name tho )

This was the initramfs I compiled for the es-8-150. I think its loady then go 0x1000000. Nothing much supported but you should get a prompt.

cesarvog · March 26, 2021, 2:40pm

Ok, here is the output of binwalking the out_m.bin (meraki):

AND here, is the binwalking output of the previous attempt with the rt-68U initramfs (found it after reviewing the GitHub history. Trying to boot gave the same results as with the previous meraki and the previous try with the wrongly chosen try):

cesarvog · March 26, 2021, 2:42pm

I can see from the above two outputs, that the meraki seem to "separate" parts of the binary content as if different "partitions" (in lack of a better term), while the rt-68U does not. While I still don't understand what any of this means, I intend to learn...

cesarvog · March 26, 2021, 2:45pm

Here is the output of the file and binwalk commands using the initramfs file kindly shared by @clayface above. As I post this, I'm currently transferring it to my US-16-150 over serial connection using YMODEM. Will report back in a few minutes.

cesarvog · March 26, 2021, 2:56pm

bootm 0x01000000 with the above transferred file did not work

Wrong Image Format for bootm command
ERROR: can't get kernel image!)

I'm currently doing a second transfer of it, after doing
mkimage -A arm -O linux -T kernel -C none -a 0x01000000 -e 0x01000000 -n linux -d ./openwrt-bcm5334x-generic-ubiquiti_es-8-150w-initramfs-kernel.bin out_es_8_150.bin

cesarvog · March 26, 2021, 3:09pm

Sorry, same result with the mkimaged file above.

anon50098793 · March 26, 2021, 3:09pm

try again without the header...
then try leaving -e and -a out of the command
then maybe try 00018000

clayface · March 26, 2021, 3:09pm

should be go not bootm with the initramfs

cesarvog · March 26, 2021, 3:12pm

Uhm, I will try again then. Should I try with the mkimaged file, or with the original file you shared?

anon50098793 · March 26, 2021, 3:13pm

not mine the switch8 one...

1 - no mkimage at all
2 - mkimage with no address
3- mkimage with your oem address? ( may be risky? )

( bootm is typically: 'bootm ADDRESS' while go is typically 'go' not too sure where it gets it's info from... so your 'loady' is putting the initramfs at an address... typically you'd type: 'bootm 0x00018000' or wherever it was loaded to )

cesarvog · March 26, 2021, 3:15pm

Right, I meant the original switch8 initramfs or the mkimaged file of it... Transferring the original switch8 initramfs now.

WINNER! ( ) thanks heaps @clayface

No Sir, thanks to all that chimed in and provided help over the last couple of days, which of course includes you in a prominent position.

I suppose I now have to find out what to do to make the network work. I've seen errors while loading OpenWrt, which seem to indicate that the switch was not recognized (Do I get right what "iproc-pcie 18013000.pcie: PHY or data link is INACTIVE!" means?) There were a few other fails above this line as well...

anon50098793 · March 26, 2021, 3:40pm

yes, fundamentally... from here on in... things get a little complex... but essentially... combinations of;

edit dts > turn dts into dtb with 'dtc' command > readd dtb to kernel and add header then test ( quite a few posts / guides on this )
same but use 'make kernel_menuconfig' and include (or remove) drivers ( also posts and guides
on this )
[guru-level] add or modify drivers within the kernel ( good luck )

most of it is beyond my skillset... but I can talk you through the 'make kernel_menuconfig' if you get a buildroot up and running...

yeah... pcie, timer and mdio are the main things to pay attention to in that output...

( even if you stop where you are... this thread is a valuable reference / starting point for anyone who comes along in the future... so it's an achievement in itself )

cesarvog · March 26, 2021, 3:41pm

So much to learn, so little neurons still working... (I'm 59, btw).
