Migrace rb453g na ath79

Migrace rb453g na ath79

ZAVER:

nejde mi to :D zkoušel jsem to tak 12h
oficiální initrd rb493g je jen v (23.5/24.10?) nebootuje nejspíš kvůli tomu, že je moc velký - viz post .. haže chybu
sysupgrade z ar71xx na ath79 asi nejde, protože tomu nerozumí? viz post
potřeboval bych funkční initrd s ath79 a až z něj flash
img initrd z buildu 21.02 mi nefunguje
build z commitu, viz post , mi nejde kvůli zavislostem gcc/g++ což je divný.. mám je :D možná se spíš rozbíji ten script/feed update -a … když jsem na commitu a ne v branch
zkusit build 19.7, přidat rb435g do ath79 a nový build mi nejde, protože nemám python2 a v tom tree ani není vůbec ještě podpora rb4xx

TODO:

můžu zkusit tam flashnout oficialni rb493 přes sysupgrade zté 23/24 verze.. ale možná jsem to zkoušel :D
- nejsem si jistý, zda ten muj build neměl problém s tím umask a jiný jsem možná nezkusil?
- stačí mi připojit seriovou linku, fallback 19.7 img dát na gw
- a jeste kabel k rb, abych mohl obnovit konfiguraci
znovu pročíst stránku zařízení, PR konverzaci, zda mi něco neuniklo :D
můžu ještě vzít starý systém, centos, a udělat build z commitu, zda to nepůjde?
- musim pohlidat, ze tam je fakt 4x kernel
můžu napsat autorovi toho patche, zda to teda má fungovat :D a zda nemá build toho img initrd :D

Plán

Pridat podporu pro 435g podle rb493
- https://github.com/openwrt/openwrt/commit/b7a8a5454226f34256c5d76480dda5abb1308395

teoreticky by mohl jet i img pro 493G ale muze to delat bordel s eth1, coz ale zase asi nepotrebuji 😄 ale aby to neco neodbouchnulo kvuli GPIO 😄

Boot z ethernetu

Nejnižší verze, která mi naběhla, byla 19.07.10 s ar71xx
nenaběhla mi žádná verze s ath79

nejspíš kvůli velikosti

» initramfs image will not work if uncompressed image size over ~8.5Mb

19.07.10 img má cca 3.9MB
24.10 img má kolem 6MB, ale nekomprimovaný má asi 13MB?

23.xx měla taky kolem 12MB
na diskuzi v PR někdo doporučoval

@flyn-org can you try building an ath79 initramfs image from commit b7a8a54 (this pr), and use that to tftp boot your router and then sysupgrade to your 8/21 image (or something newer)?

I think the „pebs“ issue is exposed when using an ar71xx image to flash an ath79 one.

a taky

Initramfs doesn't work with image size > ~8.5Mb. LZMA compression has been enabled, as 4.19 kernel buildwill boot, but a 5.4 will not. (open question).

jenomže neumím udělat build s kernelem 4.19

Vytváření 19.07

myšlenka byla, že bych zkusil sestavit initrd 19.07, která mi funguje, abych ověřil, že to builduji správně
následně bych tam portoval podporu pro rb435g

při volání /scripts/feeds update -a mám nesplněné závislosti

Build dependency: Please install Python 2.x

tak starý python už nemám a ani ho nechci zpětně cpát do systému
další problém je, že v 19.07 není ještě vůbec mikrotik v ath79, takže by přidání bylo složitější. Musel bych vzít více commitu z 21.02

Vytváření commit b7a8a54

kdyz se switchnu na commit b7a8a54, tak to sice kernel 4.19 podporuje, ale nedostanu se ani do menu config, protoze nejde provest ./scripts/feeds update -a
mám nesplněné závislosti

Build dependency: Please install the GNU C Compiler (gcc) 4.8 or later
Build dependency: Please install the GNU C++ Compiler (g++) 4.8 or later
Build dependency: Please install Python >= 3.5
Build dependency: Please install Python >= 3.5

přitom mám gcc/g++ i python3
pak je třeba dát pozor, že se možná musí vybrat kernel ručně. Jsou tam totiž dva (4.19, 5.4)

Vytváření img 21.02

jde o nejstarší branch s rb493g v ath79
preventivně umask viz workaround

umask 0022

setting up elf image... kernel out of range␍␊

zkusil jsem zmenšit velikost
odstranil jsem hlavně wifi

ls -lah bin/targets/ath79/mikrotik/openwrt-ath79-mikrotik-mikrotik_routerboard-435g-initramfs-kernel.bin
-rwxr-xr-x 1 djbuldog djbuldog 4,2M 28. dub 00.47 bin/targets/ath79/mikrotik/openwrt-ath79-mikrotik-mikrotik_routerboard-435g-initramfs-kernel.bin

pak jsem zkusil odstranit úplně maximum včetně SSH, ..
dostal jsem se na 3.6MB a nic, stejná chyba

změna targetu na rb493g taky nepomohla
všiml jsem si, že tam dává už kernel 5.4, což nesplňuje:

Initramfs doesn't work with image size > ~8.5Mb. LZMA compression has been enabled, as 4.19 kernel buildwill boot, but a 5.4 will not. (open question).

chce to zkusit build s 4.19 kernel z toho commitu?

Vytvoření img 24.10

git clone https://github.com/openwrt/openwrt.git
git checkout openwrt-24.10

./scripts/feeds update -a
./scripts/feeds install -a

aplikoval jsem patch

make menuconfig

tohle jsou změny v .config vůči default v 24.10

/scripts/diffconfig.sh 
CONFIG_TARGET_ath79=y
CONFIG_TARGET_ath79_mikrotik=y
CONFIG_TARGET_ath79_mikrotik_DEVICE_mikrotik_routerboard-435g=y

protože nepůjde stahovat instalovat kmod balíčky z repa, rozhodl jsem se nakonec přidat toho více
vyselektoval jsem hlavně kmod moduly + očekávaný software, který nastavil další připadné kmod závislosti

stáhl jsem potřebné zdrojové kódy, aby jel paralelní režim rychleji (tip z build guide)

make download

build na 24 jádrech

make -j 24

nahrání na tftp server (tftpd-hpa na pharaon)

sudo cp bin/targets/ath79/mikrotik/openwrt-ath79-mikrotik-mikrotik_routerboard-435g-initramfs-kernel.bin /srv/tftp/

na DHCP jsem nastavil přes UI tftp boot. Musí tam být servername i IP adresa.

Výroba patche pro rb435g

přidal jsem rb435g podle rb493g

cp dts/ar7161_mikrotik_routerboard-493g.dts dts/ar7161_mikrotik_routerboard-435g.dts

mel by mit jeden WAN a LAN ke switchi AR8316
v AR7161 jsou 2 MAC rozhrani, ktere potrebuji fyzicka PHY rozhrani.
vetsinou tam je 1x PHY WAN a 1x switch, jehoz jedno PHY, CPU PHY, je pripojeno k SoC
komunikace mezi SoC a externim PHY probiha pred MDIO sbernici

nasledjic vypis ukazuje, ze
- switch je zaregistrovan na mdio 0
- port 4 toho switche bude pouzit jako PHY k CPU v SoC
- SoC, MAC 1, se pripojkil k mdio 0.04 .. tj swtich port 4
- vytvorilo se z toho eth0 rozhrani.. nema to byt spis eth1? 😄
- SoC, MAC 0, se pripojilo k mdio 0, port 0?
- z toho SoC MAC 0 vznikl eth1?

estli to teda chapu, tak eth0 by mel byt LAN a eht1 wan 😄
jenomze v openwrt to je obracnee.. eth1 se bere jako lan switch

Zajímavý je, ze ten port 0 má pořád linku nahoře, i když tam není kabel. Možná tím napojením na CPU?
Takhle to vypadá, když je kabel v portu 3 (LAN2). Eth0 (WAN] nema LOWER_UP a eth1 ano

Zajímavý je, že v dmesg vidím link up a down, ale jen pro eth0 .. ne pro eth1

provedl jsem zálohu cfg
takhle vypadal funkční dmesg v 19.07 (pro srovnání s 24.10)
