Support for D-Link DIR-842 (Rev C2)

jackcolentern · July 12, 2019, 8:29pm

Hello,

I have a router in my hand, I am trying (learning) to compile openwrt for DIR-842 C2, witch is very similar to https://wikidevi.com/wiki/D-Link_DIR-842_rev_C1 with an USB2 port.

Qualcomm Atheros QCA9563 SoC
+
Qualcomm Atheros QCA9888 Wifi Chip
+
Qualcomm Atheros AR8327 Switch

I am able to connect to the serial interface and get the bootlog,

information i gathered so far:

Flash Chip: Winbond W25Q128 16MB Flash

Layout:

 0x000000000000-0x000000040000 : "u-boot"
 0x000000040000-0x000000050000 : "u-boot-env"
 0x000000050000-0x000000060000 : "devdata"
 0x000000060000-0x000000070000 : "devconf"
 0x000000070000-0x000000080000 : "misc"
 0x000000080000-0x000000f50000 : "upgrade"

 0x000000fd0000-0x000000fe0000 : "art"
 0x000000fe0000-0x000000ff0000 : "alpha_boarddat"
 0x000000240060-0x000000dd7060 : "rootfs"

Now I am trying to get access to the serial console, but I can't figure out what is the login password.

Now I managed to get the kernel booting, but it cant seems to find rootfs

I ran through the wiki and I cant find any further help.

Please help me continue, thanks in advance!

Check your kernel boot args

I'd also check into "seama", which I've never seen before myself (and may be right)

jackcolentern · July 14, 2019, 5:08am

Thanks for the quick reply, I am a little bit confused about the bootargs

In the dts file, I set the bootargs to

chosen {
		bootargs = "console=ttyS0,115200n8";
	};

But in the bootloader, if I use printenv, I can see the bootargs as

bootargs=console=ttyS0,115200 root=31:02 rootfstype=jffs2 init=/sbin/init mtdparts=ath-nor0:256k(u-boot),64k(u-boot-env),14528k(rootfs),1408k(uImage),64k(mib0),64k(ART)

May I know what is the bootargs the kernel actually uses to boot?

jeff · July 14, 2019, 5:11am

Check what the kernel prints in the early init phase -- it depends on the platform as to if the boot-loader args are taken, munged, or ignored

jackcolentern · July 14, 2019, 5:20am

Thanks again

I tried to set

setenv bootargs=console=ttyS0,960000=root=31:06

But I still find

Kernel command line: console=ttyS0,115200n8 rootfstype=squashfs,jffs2

can I safely assume the boot-loader args is ignored?

Here is the complete bootlog

Thanks, the compatible = "seama" line is copied from qca9563_dlink_dir-859-a1.dts

I think this two device is very similar so I copied the dts file and edited the partitions. I will look more into it.

jackcolentern · July 14, 2019, 10:51am

Seems like I am able to boot initramfs from tftpboot, so I assume the only problem preventing it from booting now is it cannot create seama-fw partition sucessfully for rootfs and kernel

Just throw it in the dts to test.... uboot might be setting on the fly.... or else where in the buildroot

chosen {
bootargs = "console=ttyS0,115200  root=31:06"

This was off anyway

setenv bootargs=console=ttyS0,960000=root=31:06
                                   !^

Would be more like;

setenv bootargs 'console=ttyS0,115200 root=31:02 rootfstype=jffs2 init=/sbin/init mtdparts=ath-nor0:256k(u-boot),64k(u-boot-env),14528k(rootfs),1408k(uImage),64k(mib0),64k(ART)'
then do 
printenv
to verify!

( if it sticks but does not show in the dmesg.... you can try >make kernel_menuconfig > boot > enable ATAG traditional + enable mangle [ combine ] )

Post a full printenv... ( in code tags )

I saw other seama devices printing something like

[    0.679627] 0x000000070000-0x000000ff0000 : "firmware"
[    0.715565] 2 seama-fw partitions found on MTD device firmware

[    0.734550] mtd: device 6 (rootfs) set to be root filesystem
[    0.740345] 1 squashfs-split partitions found on MTD device rootfs
when booting, but it doesn't appear, is this a problem?

Thanks in advance!

did you get an oem layout ( dmesg of whats really there )? your current vs initram log shows a "misc" partition which throws root out by 100000 ( 70000 vs 80000 ).....

if the initramfs sees your firmware@70000 then maybe try a dts with that.... ( comment out or remove misc )???

The initram bootlog is based on the old build which I set the layout incorrectly, I already fixed it. The bootlog of the original dlink firmware shows

[    0.620000] 0x000000000000-0x000000040000 : "u-boot"
[    0.620000] 0x000000040000-0x000000050000 : "u-boot-env"

so if I analyse the problem correctly, the problem I am facing now is the kernel is unable to create rootfs and kernel partition when booting, because of the missing of

2 seama-fw partitions found on MTD device firmware

when booting (other seama devices shows it) , am i correct?

Thanks again

i'd say "detect"

see if you can enter the bootarg command i wrote above in uboot and if it sticks, and if the kernel prints it..... then it will be fast to try some variations.... rather than the dts

if you try a few more things and it still aint happy, yes... next stop is the seama logic...... i cant find the c1 config anywhere.... dunno what your basing your stuff on.....

Thanks!

I worte

setenv bootargs=console=ttyS0,960000 root=31:05

and it does show in printenv, but the kernel doesn't print it when booting.

I will try to enable ATAG traditional + enable mangle [ combine ] , I will let you know the result in a second.

anon50098793:

Would be more like;
setenv bootargs 'console=ttyS0,115200 root=31:02 rootfstype=jffs2 init=/sbin/init mtdparts=ath-nor0:256k(u-boot),64k(u-boot-env),14528k(rootfs),1408k(uImage),64k(mib0),64k(ART)'
then do 
printenv
to verify!
( if it sticks but does not show in the dmesg.... you can try >make kernel_menuconfig > boot > enable ATAG traditional + enable mangle [ combine ] )

hey where did 06/05 come from.... this says 31:02....

Pilot6 · July 14, 2019, 12:06pm

What about something like

bootargs-append = " mtdparts= root=31:06";

in dts. This will drop all u-boot params regarding mtd.

jackcolentern · July 14, 2019, 12:08pm

But this

setenv bootargs 'console=ttyS0,115200 root=31:02 rootfstype=jffs2 init=/sbin/init mtdparts=ath-nor0:256k(u-boot),64k(u-boot-env),14528k(rootfs),1408k(uImage),64k(mib0),64k(ART)'

Oops, sorry for my mistake, but it still doesn't show in the kernel bootlong
