Jau antr\u0105 kart\u0105 \u0161iais metais ir ne\u017einia kelint\u0105 kart\u0105 per vis\u0105 aviet\u0117s<\/em> naudojimo istorij\u0105 gri\u016bna<\/em> SD kortel\u0117. Tiesa pati pirmoji naudota, kuri, jei nemai\u0161au buvo 2GB microSD \u012fd\u0117ta \u012f per\u0117jim\u0105, veik\u0117 pakankamai patikimai kol nebuvau priverstas pakeisti \u012f ka\u017ek\u0105 talpesnio. <\/p>\n

Toliau sek\u0117 bent keleta 4GB korteli\u0173, vien\u0105 i\u0161 j\u0173 (paskutinioji) buvo Kingston gamintojo.<\/p>\n

Taigi nusipirkau vos ne pirm\u0105 pasitaikiusi\u0105, pigiausia (~11\u20ac) USB d\u0117\u017eut\u0119 2.5″ SATA diskui, susikuriu boot<\/em> ir root<\/em> particijas (taip kaip nurodyta daryti \u0161vie\u017eiai diegiant Archlinux’\u0105 \u012f aviet\u0119<\/em>). I\u0161traukiu SD kortel\u0119, pajungiu HDD ir… diskas nesisuka, pasirodo per silpnas maitinimas. Maitinimas HP 1A pakrov\u0117jas. Greitai pasikui\u010diu stal\u010diuje ir randu HTC pakrov\u0117j\u0105. Ant jo taip pat ra\u0161o 1A.<\/p>\n

Prie HTC pakrov\u0117jo jungiu USB d\u0117\u017eut\u0117s vien\u0105 i\u0161 USB (d\u0117\u017eut\u0117 turi dvi USB jungtis, kad b\u016bt\u0173 galima i\u0161karto pajungti \u012f dvi USB jungtis, tam, kad diskui u\u017etektu srov\u0117s i\u0161 USB jung\u010di\u0173). Kit\u0105 jungiu \u012f aviet\u0117s<\/em> USB. Pa\u010di\u0105 aveit\u0119<\/em> u\u017emaitinu nuo HP pakrov\u0117jo.<\/p>\n

Viskas startuoja, bet pala… OS nesikrauna. Greitas pagooglinimas ir paai\u0161k\u0117ja, kad kompiuteris moka startuoti tik i\u0161 SD kortel\u0117s. Taigi SD kortel\u0117 gr\u012f\u017eta \u012f savo viet\u0105, bet prie\u0161 tai atsidarau boot particijoje esan\u010di\u0105 byl\u0105 \/boot\/cmdline.txt<\/em> ir joje paredaguoju root<\/em> reik\u0161m\u0119. Rezultate turiu toki\u0105 eilut\u0119:<\/p>\n

\r\n[dinux@alarmpi ~]$ cat \/boot\/cmdline.txt\r\nroot=\/dev\/sda2 rw rootwait console=ttyAMA0,115200 console=tty1 selinux=0 plymouth.enable=0 smsc95xx.turbo_mode=N dwc_otg.lpm_enable=0 kgdboc=ttyAMA0,115200 elevator=noop init=\/usr\/bin\/init\r\n<\/pre>\n
V\u0117l jungiu. Viskas veikia, OS kraunasi. Krovimasis \u017eymiai spartesnis nei i\u0161 SD kortel\u0117s.<\/p>\n
D\u017eiaugiuosi situacija gal vien\u0105 dien\u0105.. aviet\u0117<\/em> pakimba, na gal kas nutiko…, perkraunu, dar po dienos ar dviej\u0173 v\u0117l kabo<\/em>. Patikrinu log’us, matau:<\/p>\n
\r\nusb 1-1.3: device descriptor read\/64, error -71\r\n<\/pre>\n
Googlinu. Ka\u017eko labai naudingo nerandu. Nusprend\u017eiu, kad gal tai d\u0117l maitinimo tr\u016bkumo. Sukei\u010diu pakrov\u0117jus. Dabar HP maitina disk\u0105, HTC kompiuter\u012f. Pana\u0161u, kad b\u0117da dingo. Bet mintis, kad viskas veikia “ant ribos” ir nelabai tvarkingai (du pakrov\u0117jai) neduoda ramyb\u0117s.<\/p>\n
Ie\u0161kau pas kinus galingesnio maitinimo, galvoju gal vis d\u0117lto pajungti taip vadinama industrin\u012f 5V maitinim\u0105, bet paskui nety\u010dia aptinku 3.1A USB pakrov\u0117j\u0105 su dviem jungtim<\/a>. Nuotraukoje parodytos dvi USB jungtis, prie vienos para\u0161yta 2.1A prie kitos 1A. Realyb\u0117j nusipirkus \u0161\u012f pakrov\u0117j\u0105 \u0161i\u0173 u\u017era\u0161\u0173 n\u0117ra.<\/p>\n
HDD jungiu \u012f t\u0105 USB kur puslapyje para\u0161yta 2.1A, aviet\u0119<\/em> prie 1A.<\/p>\n
Dabar jau sistema veikia ka\u017ekiek laiko ir galima teigti, kad viskas tikrai gerai, joki\u0173 l\u016b\u017eim\u0173, joki\u0173 klaid\u0173 loguose.<\/p>\n","protected":false},"excerpt":{"rendered":"
