[SOLVED] Unexpected magic number?

phongshader · April 9, 2018, 1:50pm

This is my 1st time compiling anything so go easy on me. I'm trying to resurrect a pair of Meraki MR24s. I tried to load lede-17.01.4-apm821xx-nand-mr24-initramfs-kernel.bin and got this:

Wrong Ramdisk Image Format
Ramdisk image is corrupt or invalid

So I tried my hand at compiling my own image and got this:

=> setenv netloadmethod tftpboot; setenv bootargs console=ttyS0,$115200 rootfstype=squashfs mtdoops.mtddev=oops; run meraki_load_net meraki_checkpart meraki_bootlinux

Unexpected magic number 27051956

What is a magic number, how do I get an expected magic number?

hm, I see one problem. In the text you said you used:
lede-17.01.4-apm821xx-nand-mr24-initramfs-kernel.bin

but the log says you uploaded:
openwrt-apm821xx-nand-meraki_mr24-initramfs-kernel.bin

Now, the issue is that we had to switch the MR24 initramfs image generation since the kernel got too big to fit into the reserved space and because of this, the old initramfs boot code no longer works:

https://github.com/openwrt/openwrt/commit/e2b35f91b38f668976cc8a8e08843cf853d9be71

Look at the commit, to see how to load the new openwrt-apm821xx-nand-meraki_mr24-initramfs-kernel.bin, or visit the wiki.

Thanks for the reply, I will take a look at the wiki.

As I said in my 1st post this is all new to me. I want to walk through this to make sure I understand and I'm doing this correctly. If my tftp serverip = 192.168.1.1 mr24 ipaddr = 192.168.1.101 then what are the variables
{meraki_loadaddr}, {meraki_loadaddr_kernel}, {meraki_loadaddr_fdt} for the following?

setenv lede_load1 ubi read \${meraki_loadaddr} kernel  
setenv lede_load2 ubi read \${meraki_loadaddr} recovery
setenv lede_bootkernel bootm \${meraki_loadaddr_kernel} - \${meraki_loadaddr_fdt}
setenv lede_bootargs setenv bootargs console=ttyS0,\${baudrate} rootfstype=squashfs mtdoops.mtddev=oops
setenv lede_boot run meraki_ubi lede_bootargs\; run lede_load1 meraki_checkpart lede_bootkernel\; run lede_load2 meraki_checkpart meraki_bootlinux
setenv bootcmd run lede_boot
saveenv

chunkeey · April 10, 2018, 8:02pm

the ${meraki_loadaddr} (in fact all the meraki_etc...) variables are already declared in the u-boot by meraki. you can enter

printenv

into the u-boot shell to show what these variables are set to. But usually they are just fine the way they are. You don't need to change those.
If you are interested in the u-boot itself, you can find the full sources in Chris Blake's mr24-20170427 tree:

As for lede-17.01.4-apm821xx-nand-mr24-initramfs-kernel.bin. I think you are using the image hosted on openwrt/lede download servers, right? Because it is known to be broken: See https://bugs.openwrt.org/index.php?do=details&task_id=1097 and sadly this was never resolved. Building it locally (on your own PC) does produce a working image though so no idea what the builder was doing. But neither Chris Blake nor I can trigger a rebuilt/reupload. So we have been in this frustrating situation for a while.

That said, the initramfs image is a "live"-image and it doesn't overwrite the existing firmware from Cisco Meraki. (The real installation/flashing is performed by sysupgrade - this is step 7 in the new OpenWrt wiki). For now, you can get by with the lede-17.01.3 initramfs image. Just download it and tftp it and once the MR24 has booted the lede-17.01.3 "live" image, you can just install the lede-17.01.4's version of the mr24-squashfs-sysupgrade.tar via sysupgrade (this was working last time I checked).

So, the script in the Wiki can be copied/pasted into u-Boot verbatim?

I have an MX60W.

The baudrate is bad. "console=ttyS0,$115200" in the kernel bootargs got misinterpreted. It should be "console=ttyS0,115200".

can you try the following in the u-boot shell.

setenv lede_bootargs setenv bootargs console=ttyS0,115200 rootfstype=squashfs mtdoops.mtddev=oops
saveenv

and then just follow through step 3 as usual:

setenv netloadmethod tftpboot; run lede_bootargs; run meraki_load_net meraki_checkpart meraki_bootlinux

usually yes. Sometimes the author will leave the => or DEVICE# prompt in front of the command. Or add the outputs from the commands as well. etc. Also, the serial connection can easily mess up.

17.01.3 and 17.01.2 are not wokring on MX60W. I never receive an IP, nor can I ping 192.168.1.1. Since I can't reach LuCI, I cannot flash. Since I receive no Internet connection, I can't download anything to the router.

NVM I figured it out

lleachii · April 13, 2018, 5:10am

OK, you're still trying to move board config...

you have to list it:

ubinfo /dev/ubi0 -N board-config

Then use that number (mine was 0_2).

So is yours..

dd if=/dev/ubi0_2 of=/tmp/board-config.img
ubirmvol /dev/ubi0 -N board-config
ubimkvol /dev/ubi0 -s 24KiB -N board-config
ubiupdatevol /dev/ubi0_0 /tmp/board-config.img

Be sure you understand what you're doing.

EDIT: the MR24 instructions say 24KiB, other Merakis are different sizes.

phongshader · April 13, 2018, 1:32pm

Thank you for the answer lleachii
I hate to say it, but at the moment, I don't understand what I'm doing but I'm learning with the help of all of you.
Thanks again!

chunkeey · April 13, 2018, 3:51pm

yes, the indent in the commit message was badly placed.
It's probably the best to just point everyone to the wiki:

As for the "board-config" partition. You can do it, but you might as well just skip it.
There's not much to be gained since your board-config partition will still be 2 LEBs. I'll ask Chris to update the wiki.

lleachii · April 13, 2018, 5:28pm

Does the board-config partition contain anything needed for OpenWRT?

It only appears 2-3 lines long, mostly noting the model and part numbers for the MX60 and MX60W, respectively. The rest of the partition is filled with all 1's (FFFFFFFFFFF.....).

chunkeey · April 13, 2018, 7:13pm

the board-config contains the system's ethernet mac.

github.com

openwrt/openwrt/blob/master/target/linux/apm821xx/base-files/lib/preinit/05_set_iface_mac_apm821xx

preinit_set_mac_address() {

I'm stuck on step 7
7. Once done, you can now load up LuCI at 192.168.1.1, and use the sysupgrade option to flash the full image to the device using the sysupgrade file named openwrt-apm821xx-nand-meraki_mr24-squashfs-sysupgrade.tar. From this point on, any future updates/builds can just be flashed through LuCI.
I'm not sure how I load up LuCI. I'm assuming that I enter 192.168.1.1 into my browser and the gui should show up but thats not what happens..."This site can't be reached" is there a way to run the sysupgrade from the console?
