Ma kēia ʻāpana ke nānā nei au i kekahi o nā koho hoʻoponopono i pono iaʻu. ʻAʻole kēia he papa inoa piha o nā mea a buildroot e hāʻawi ai, akā hana nui lākou a ʻaʻole koi i ke komo ʻana i nā faila o buildroot ponoʻī.
Ke hoʻohana nei i ka mīkini EXTERNAL no ka hana maʻamau
Ua nānā mākou i kahi hiʻohiʻona maʻalahi o ka hoʻohui ʻana i kāu hoʻonohonoho ponoʻī ma ka hoʻohui ʻana i ka defconfig o ka papa a me nā faila pono i ka papa kuhikuhi Buildroot.
Akā ʻaʻole maʻalahi kēia ʻano, ʻoi aku ka maikaʻi o ka hoʻonui ʻana i buildroot. Aia kahi hana e hoʻoponopono ai i kēia pilikia lāʻau waho. ʻO kona kumu, hiki iā ʻoe ke mālama i ka papa, configs, packages a me nā papa kuhikuhi ʻē aʻe i kahi papa kuhikuhi kaʻawale (no ka laʻana, hoʻohana wau i ka papa kuhikuhi patches e hoʻopili i nā patches i nā pūʻolo, nā kikoʻī hou aku ma kahi ʻāpana ʻokoʻa) a na buildroot ponoʻī e hoʻohui iā lākou i nā mea i loko. kona papa kuhikuhi.
Hoʻomaopopo: hiki iā ʻoe ke uhi i kekahi mau lāʻau waho i ka manawa hoʻokahi, aia kahi laʻana ma ka manual buildroot
E hana kāua i kahi papa kuhikuhi my_tree, aia ma ka ʻaoʻao o ka papa kuhikuhi buildroot a hoʻololi i kā mākou hoʻonohonoho ma laila. ʻO ka hoʻopuka ʻana e like me kēia ʻano faila:

papa kuhikuhi papa Loaʻa nā faila i kēlā me kēia papa i kā mākou hihia:
- ʻO bef_cr_fs_img.sh kahi palapala e hoʻokō ʻia ma hope o ke kūkulu ʻana i ka ʻōnaehana faila i manaʻo ʻia, akā ma mua o ka hoʻopili ʻana i nā kiʻi. E hoʻohana mākou iā ia i ka wā e hiki mai ana
- linux.config - hoʻonohonoho kernel
- rootfs_overlay - ka papa kuhikuhi e uhi ai ma luna o ka ʻōnaehana faila
- users.txt - he faila e wehewehe ana i nā mea hoʻohana e hana ʻia
papa kuhikuhi hoʻonohonoho aia ka defconfig o kā mākou papa. Hoʻokahi wale nō mākou.
pūʻolo - papa inoa me kā mākou pūʻolo. I ka wā mua, loaʻa i buildroot nā wehewehe a me nā lula no ke kūkulu ʻana i kahi helu palena o nā pūʻolo. Ma hope e hoʻohui mākou i ka icewm window manager a me ka Slim graphical login manager maanei.
Pāpale - hiki iā ʻoe ke mālama maʻalahi i kāu mau paʻi no nā pūʻolo like ʻole. Nā kikoʻī hou aku ma kahi ʻāpana ʻokoʻa ma lalo nei.
I kēia manawa pono mākou e hoʻohui i nā faila wehewehe no kā mākou lāʻau waho. Aia 3 mau faila ke kuleana no kēia: external.desc, Config.in, external.mk.
waho.desc aia ka wehewehe maoli:

$(BR2_EXTERNAL_my_tree_PATH)/board/my_x86_board/users.txtʻO ka laina ʻelua he wehewehe pōkole a hiki ke heluhelu ʻia e ke kanaka.
Config.in, waho.mk - nā faila e wehewehe i nā pūʻolo i hoʻohui ʻia. Inā ʻaʻole ʻoe e hoʻohui i kāu mau pūʻolo ponoʻī, a laila hiki ke waiho ʻia kēia mau faila. I kēia manawa, ʻo ia kā mākou e hana ai.
I kēia manawa ua mākaukau kā mākou lāʻau waho, aia ka defconfig o kā mākou papa a me nā faila e pono ai. E hele kāua i ka papa kuhikuhi buildroot a kuhikuhi e hoʻohana i waho-lāʻau:

Ua ʻike ʻia kahi mea koho waho ma ka papa kuhikuhi:

ʻOi aku ka mea nui iā mākou e kākau hou i nā ala kūpono e hoʻohana ai i waho-lāʻau.

Hiki ke hana i kēia ma ka ʻāpana System configuration:
Hoʻokō ʻia nā palapala ʻelua ma hope o ke kūkulu ʻia ʻana o ka ʻōnaehana file target, akā ma mua o ka hoʻopili ʻia ʻana i nā kiʻi. ʻO ka ʻokoʻa, ua hoʻokō ʻia ka palapala fakeroot i ka pōʻaiapili o fakeroot, e hoʻohālikelike ana i ka hana ma ke ʻano he kumu hoʻohana.
Hoʻokō ʻia ka palapala hope ma hope o ka hana ʻana o nā kiʻi ʻōnaehana. Hiki iā ʻoe ke hana i nā hana hou i loko, no ka laʻana, kope i nā faila e pono ai i kahi kikowaena NFS a i ʻole e hana i kahi kiʻi o kāu polokalamu firmware.
Ma keʻano he laʻana, e hana wau i kahi palapala e kākau i ka mana a kūkulu i ka lā i /etc/.
