Sorry you lost me there... I suppose you're saying that we need to take the above trx file and run it through some sort of utility, that will add some kind of header to it and make it compatible with u-boot... Is that it?
Where can I get this mkimage? It's not available on my Mac. Do I have to download it on Linux, or does it come with some developer tools I need to apt install?

yeah... debian is;

apt-get install u-boot-tools

although there is also one compiled within the buildroot when you build it...

generally something like this off the top of my head...

mkimage -A arm -O linux -T kernel -C none -a 0xLOADADDR -e 0xLOADADDR -n linux -d ./openwrt-bcm53xx-generic-asus_rt-ac68u-initramfs.trx out.bin

here is your likely loadaddr? and why -C none

Ok, will install a Debian VM with no desktop on my VmWare fusion, and also install u-boot-tools, then get back to you.

Just occurred to me, should I have opted for a 32bit Debian install?

nao, 64 is correct

Wow, just noticed you are based on the other side of the Globe. Don't you ever sleep? :wink:

one day I hope to... :wink:

adding this here for reference... seems to be an upstream dts sample intree for this soc ( switch8 / hurricane2 ) ( correction it's BCM53342 yours is BCM53343 but close )

may come in handy further down the track...

( I know 3 words in brazillian... and the 3rd is berimbau :wink: )

Took me quite a while to be able to get the out.bin file, because stubborn Debian on the VM would not cope with the VMWare Tools, that make copy/paste operations between host and VM easy...
Will report back in a few more minutes, once this file transfer is done.
3 More Portuguese Brazilian Words for your growing vocabulary:
OBRIGADO = thank you (when used by males, OBRIGADA, if used by females)
POR FAVOR = Please
DESCULPE-ME = Forgive me

By the way, here is the terminal output of the mkimage command:

Since you know this word, I suppose you are fairly young and somehow came to play "Capoeira" (Brazilian martial art)

It tries to boot, but apparently hangs:

2 years..., they called me catatau... (a bird?)... not so young any more... :wink:

ok... the good news...

  • you almost setup for a buildroot so you can generate stuff if you need to ( homework )
  • you've learn't the mkimage command so you can format initramfs in a way that uboot expects to find them

why didn't it work?

  • wrong cpu?
  • wrong serial in dts ( may be working and no output )
  • wrong loadaddr
  • wrong format within the initramfs ( ubnt checks or expects to find something else there that we have not included )

at this point we should probably wait for someone more wise to DESCULPE us... they will probably say whether or not [BCM53343] is actually supported in the linux driver tree...

otherwise you can;

  • keep learning go through the buildroot basic tutorial...
  • research that board 'switch8' and maybe see of there are any internet references to it's hardware / .bin loading etc...
  • possibly get the flash partition layout... ( actually I think it's already in the boot stuff you posted above )

Catatau is a friendly nickname for short/young fellas. Remember Yogy the bear cartoon. Catatau is what they named it's shorter and smarter sidekick when it aired in Brazil several years ago...

Muito Obrigado! (Many Thanks!)
I will try to move on with the homework and see if I can get any further.

That device has a Broadcom Hurricane 2 SoC. Support for the SOC was added around Linux 4.16. Currently the only DTS I am aware of that makes use of the SOC support is for the Ubiquiti UniFi Switch 8 (bcm53340-ubnt-unifi-switch8.dts).

I thought I would add a complete Serial boot log, obtained from another US-16-150 switch I have here, this second one in perfect working condition, in case someone more experienced can spot something obvious an unexperienced fella like me would leave unnoticed (diff anyone :wink:):

Hey @wulfy23 ,

Would you be so kind as restore that initramfs file you provided yesterday?
I just noticed that I made a beginners mistake and used the whole trx file available for the rt-68U, and not the one you provided for download. I don't know what happened, I think I was a little too anxious and ended up choosing the wrong file when I copied from my Mac to the VM. And worst of all, I then erased the correct file!
As I was reviewing my steps yesterday I noticed the file had the following name "openwrt-19.07.6-bcm53xx-asus-rt-ac68u-squashfs.trx" and not "openwrt-bcm53xx-generic-asus_rt-ac68u-initramfs.trx" as per your link above.
I tried downloading again from the above link, but it did not work. I guess you may already removed it...
TIA

use the meraki one... its a closer match...

ROFL... bastards told me it was a bird :shushing_face: :face_with_hand_over_mouth:

so when you install the debian prerequisites... apart from selecting your target/device... two things and one directory you should be aware of...

(make menuconfig)

  1. enable 'ramdisk' (initramfs) images


    2-ramdisk

  2. enable logs ( useful to grep for the actual image creation commands and paths )


  3. Once you do a build with the options above enabled... you will find raw kernel / initramfs building blocks under build_dir > target* > linux-*

$ ls build_dir/target-arm_cortex-a9_musl_eabi/linux-bcm53xx_generic/ | grep -E '(zImage|vmlinux)'
vmlinux
vmlinux.debug
vmlinux.elf
vmlinux-initramfs
vmlinux-initramfs.debug
vmlinux-initramfs.elf
zImage
zImage-initramfs

these will come in handy later if you attempt to append manually the 'switch8' dts/dtb...

( note: remember to use a normal user for all buildroot operations )

OpenWrt will boot on this device (did so with an ES-8-150w) and most if not all peripherals can be made to work, but you won't be able to get very far with networking. Believe you need to look at porting Broadcom's OpenNSL for switch support.

Tks for chiming in. Definitively out of my league...

Thanks again!
Same results. It tries to boot and hangs at the same point as my previous attemp.
