ZAVER:

• nejde mi to :D zkoušel jsem to tak 12h
• oficiální initrd rb493g je jen od verze 23 (23.05.0, 23.5.5, 24.10). Nebootuje nejspíš kvůli tomu, že je moc velký.. projevuje se to tak, že po vypsání Starting Kernel at 80060000… se zasekne
• sysupgrade z ar71xx na ath79 asi nejde, protože je tam "pebs" issue.
• 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

  • https://github.com/openwrt/openwrt/pull/3026

• tady nejaky bug s init ramdiskem.. na ktery muzu narazit pri portovani
  • https://github.com/openwrt/openwrt/issues/7591

• tohle taky zajimavy bug
  • https://github.com/openwrt/openwrt/issues/8176

• 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

• 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

• 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)

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

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

• změna targetu na rb493g taky nepomohla

• 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
