Headed to rest.
After cleanup I will also need to figure out how to make a flashable image and flash it :slight_smile:

32

The ath10k “error -2” lines are normal. It has a list of places to look for each of several files it needs and -2 is file not found for that option as it checks all the possible places. Unfortunately it doesn’t report success!!

33

Stuck on creating a firmware that will be able to flash itself onto the router... or, better, will set uboot variables and also flash itself (aka oem to openwrt) :slight_smile:
My progress so far:

  • Backed up all partitions using luci while running from ramdisk.
  • The uboot was trying to move around some files if booting from flash (it was part of the scripts in u-boot configuration) so I removed that part from uboot env
  • I changed the partition layout in the image to unite “kernel” and “rootfs” in one called “firmware”
  • I flashed the openwrt image with uboot directly to flash memory at the firmware partition start address
  • Tried to boot - kernel panic :-/

one way to go might be to enable cmdline bootargs ( if needed in make kernel_menuconfig )

then muck about with manually feeding the partlayout while your in the testing phase.....

( example from one of jeffs posts ... not sure how relevant to what you have now but a starting point )

console=ttyS0,115200 root=31:03 rootfstype=jffs2 init=/sbin/init mtdparts=ath-nor0:256k(u-boot),128k(uboot-env),2048k(kernel),13888k(rootfs),64k(ART);ath-nor1:16M(opt) mem=128M

Don't save your ubootvars... just setenv over serial each boot while your testing.....

That's what i'd try anyway...... otherwise you have to go the long way ( i.e. non relevant sample CF-E110NV2 flashing issue ) or similar..... my uboot will take a dts option.... so that can speed things that way a tad ( load from tftp ) .... setenv is the fastest....

37

Last step, in my book. Sometimes the most annoying. I spent days of nights looking through the assembly and low-level C code for the early init process trying to figure out how to get the EA8300 to boot an OpenWrt image without any serial access as its boot loader was sending the "wrong" command line. That's a nicety, but not a requirement.

There's some major "black magic" in the way that OpenWrt patches early init for various platforms. Some completely ignore the passed command-line args, others "munge" it in subtle or brutal ways. Unfortunately for someone working with a single board, the same kernel is used for all boards on a given target/subtarget, so you can't really tweak it on a board-by-board basis.

At least fgrep -ri cmd target/linux/ath79/patches-4.14/ didn't raise any red flags.

For development/test purposes, poking at what U-Boot is sending through setenv as wulfy23 suggests to (a) see if you can change at all, and (b) change to something "useful"

Thanks wulfy23
I did play with it for a bit until jeff posted his comment...

Fixed a typo in .dts, building... I can change environment variables in uboot, don't know if it is passed over to kernel though...

Well, bricked it until I get a flasher... it self-destructed due to incorrect addressing from the typo in dts. Cant access the second chip at all for some reason but it is a mirror of the first one and I can read it, besides I do have partition images saved from luci.

Do you still have U-Boot running?

If so, it should all be recoverable, either with an initramfs image, or using U-Boot TFTP and U-Boot commands to write to flash.

41

Nope, it erased some part of uboot env (judging by the address space) and now CLI is silent on power-on.
I will de-solder the flash IC and flash it with SPI writer, or maybe with a clip in order to not even mess with the soldering... there are still many finishing to do even if it boots - need to get a ram image with capability to flash enclosed sysupgrade image and redefine stock U-Boot arguments otherwise it tries to manipulate files within the image prior to boot:

It’s a slow, often frustrating process the first time. OK, the second and third time too. Take your time and work on something else when things look dim. Often they’re brighter on return a couple days later.

It may be possible to keep the OEM boot args, depending on if the upgrade scripts can handle them. For me, I’ve been getting it running, then worrying about upgrade and OEM install.

From a "firmware" partition with compatible string, kernel and rootfs are automatically detected.

Thanks, added this line to the layout and updated file in the repo to reflect what it looks like now...

Is there a way to flash image from ram and luci? I only managed to write to flash through u-boot and it requires the use of CLI, while u-boot (on this device in stock configuration auto-downloads a ramdisk image and runs it from ram without the need to use cli.
My device is bricked now due to a typo I made in the flash layout, I'm waiting for a flasher from ebay.

Take a look at how sysupgrade works. It's a script that uses sh functions from /lib/upgrade/ You should be able to very carefully use the OpenWrt mtd utility to flash from the command line.

46
  1. boot your device with OpenWrt initramfs image by using follows when booting:
Using eth0 device
TFTP from server 192.168.1.100; our IP address is 192.168.1.1
Filename 'c65_atnboot.bin'.
Load address: 0x81000000

  1. send sysupgrade image via scp or upload on LuCI
    scp (image name) root@192.168.1.1:/tmp/
    or
    (if LuCI is included in your initramfs image) access to 192.168.1.1 via web browser and move to firmware upgrade page, select sysupgrade image

  2. perform sysupgrade
    sysupgrade /tmp/(image name) on ssh
    or
    Proceed on LuCI

EDIT: Of course, this requires the wired network works properly on OpenWrt...

I did try sysupgrade while booted from OpenWrt initramfs but it did not work, after restart the old kernel was still there. Hope it did not overwrite anything else in the background. This might be due to incorrect image map I guess. Will give it another try after reviving the unit. I also have some movement with Arista support on getting the sources but slow. Maybe will get their "SDK".

48

If default_do_upgrade is specified and special partition name is not specified for the device in ath79/base-files/lib/platform.sh, sysupgrade command writes the firmware passed by argument to the partition labeled "firmware". (common.sh#L229 and platform.sh#L5)

If there is no "firmware" partition, execution of the sysupgrade command should fail and the contents of the flash are not changed.

Thanks for referencing the ath79/base-files/lib/platform.sh, when I started there was nothing defined in there and firmware partition was mapped after kernel. Now it makes more sense.

50

There should be a "default" value in platform.sh -- from master

platform_do_upgrade() {
	local board=$(board_name)

	case "$board" in
	jjplus,ja76pf2)
		redboot_fis_do_upgrade "$ARGV" linux
		;;
	ubnt,routerstation|\
	ubnt,routerstation-pro)
		redboot_fis_do_upgrade "$ARGV" kernel
		;;
	*)
		default_do_upgrade "$ARGV"
		;;
	esac
}
