Sawirka, kernel-ka Linux ayaa salaan kuugu soo diraya GPIO.
Qaybtan ka mid ah sheekada ku wareejinta RISC-V RocketChip guddiga Shiinaha ee leh Cyclone IV, waxaan wali sii wadi doonaa Linux, sidoo kale waxaan baran doonaa sida loo habeeyo kontoroolka xusuusta IP Core nafteena oo wax yar wax ka beddelo sharaxaadda DTS ee qalabka. Maqaalkani waa mid sii socda , laakiin, si ka duwan kii hore ee caddaaladda ahaa, waxay noqon doontaa mid gaaban.
… Sababtoo ah setup_smp loo yaqaan kaliya haddii kernel-ku lagu habeeyey taageerada SMP, waxaad isku dayi kartaa inaad joojiso multi-core. Waxay noqon doontaa wax aan fiicneyn haddii aan sidoo kale u baahdo inaan hirgeliyo taageerada atomity ee moduleka xusuusta (waxay ii muuqatay in khasnadaha khasnadaha leh kan keligiis ah), laakiin kiiska hal-core waa in uusan na faragelin.
Wali ma kicin...

Dhab ahaantii, waa inaad wax ka qabataa dhibaatada asalka ah: meelaynta qaladka printk galay shaqo of_find_node_by_type, oo loo isticmaalo koodhka raadinta kernel-ka boot processor, wuxuu muujinayaa inay aragto nooc ka mid ah qashinka halkii ay ka heli lahayd magacyada nooca aaladaha.

Ka dib markii aan raadiyey bytes ee sawirka kernel-ka, waxaan helay iyaga, eegay offset, oo ogaaday cad: xajmiga kernel ee xuduudaha boot si cad ayaa loo yareeyey: waxaa loo qoondeeyey 8Mb, laakiin waxay qaadataa in ka badan toban.

[ 0.770000] This architecture does not have kernel memory protection.
[ 0.770000] Run /init as init process("Time-stamped" khadadka waxaa soo saara kernel, hortooda geedka waxaa soo saara BBL) Dhanka kale, FDT si guul leh ayaa loo akhriyaa, dhinaca kale, nooc ka mid ah wax aan macno lahayn ayaa laga helaa la soo koobay " shay” geed.
Intii lagu gudajiray habka qaladka, waxaan ogaaday in BBL aysan akhrin karin ciwaanka "laba jeer", ma aha sababtoo ah waxaa jiray qalad ku jira qaabeynta, laakiin si fudud sababtoo ah xididka xididka ayaa lahaa #address-cells = <1>; #size-cells = <1>;.
Kordhinta wax-soo-saarka cilladaha, waxaan arkay tilmaamayaashaas type и name "lagu garaacay", iyo si la yaab leh: byte-koodii ugu horreeyay (laga bilaabo eber) ayaa dib loo dejiyay eber, wax la mid ah 0xabcdef -> 0xab00ef. Waxay ahayd inaan isticmaalo xeelad la yaqaan: ogaanshaha cinwaannada halka ay ku taal xusuusta dhaawacan, ku dar shaqada printk daabac xogtan. Hagaag, caqabadaha laftooda printk ku kala firdhi meesha ay ku yar yihiin. Hoogay, aad uma cadda. Ka dib waxaan bilaabay inaan la tashado kuwii la kala diray objdump nooca, gacanta u deji meelaha goynta oo u gudub qaybta dhibka leh ee koodka tallaabo tallaabo. Kadibna wax qarsoodi ah oo aan fiicneyn ayaa la ogaaday: haddii aan isla markiiba dejiyo meel ka fog meel ka fog gobolka wanaagsan ee la yaqaan, ka dibna, joojinta, waxaan arki doonaa xusuusta horeba u dhaawacantay. Laakiin haddii aad isku daydo in aad si aamusnaan ah ugu soo dhuumato tallaabo tallaabo tallaabo, buggu waxa uu maareeyaa in uu qariyo! Waxay u uraysaa sida kontoroolka xusuusta ee jabay iyo kaydka qarinaya qaladka haddii aad si joogto ah u codsato qiimaha loo baahan yahay. Maxaa dhacaya haddii…
Bedelida xusuusta
Anigoo ku dheggan fursadda aan ku xalin karo dhib aan dhinaceyda ka jirin, waxaan u qaatay in laga yaabo in aan hadda helay ul xusuusta oo jaban. Kadib waxaan xasuustay in netbook toban jir ahi aanu ahayn kombuyuutar la qaadi karo oo keliya, balse uu sidoo kale yahay il qiimo leh oo DDR2 SO-DIMM ah. Gunno ahaan, waxaad ku dhejin kartaa xusuusta laga saaray sabuuradda oo aad Memtest ku dhejin kartaa isla markiiba (Linux, jidka, wuxuu ku raran yahay ku dhawaad qolofka garaafyada. Laakiin way fiicantahay inaadan ku celin tijaabadan haddii aad qiimeyso macluumaadka ku jira saxanada rakiban...). Dhinaca kale, waxaan u qaadan karnaa in xasuustu aysan si fudud ugu habboonayn shabkada gaarka ah. Dhanka kale, wuxuu awooday inuu kabaha kabo! Waxaa jirtay rajo ah in xusuusta ay si fudud u "jabtay", dhibaataduna kuma aysan jirin duubkayga.
Tani waxay ka dhigan tahay inaad u baahan tahay inaad isku daydo inaad si ku meel gaar ah u bilawdo xusuusta netbook. Nasiib darro, Quartus 18 ma garanayo sida loo cusboonaysiiyo IP Core si loo tafatiro. Tani waxay ka dhigan tahay in ugu dambeyntii la gaaray waqtigii la baran lahaa sida loo abuuro xaalado cusub. Wax kastaa waxay noqdeen wax fudud: waxaan u eegeynaa IP Catalog shayga DDR2 SDRAM Controller oo leh ALTMEMPHY Intel FPGA IP waxaanan helnaa baloog leh isla interface kii hore. Dhibaatada kaliya ayaa ah dejinta goobaha xusuusta saxda ah.
Helitaanka xuduudaha moduleka xusuusta
Waxaa jira hab cad oo cad oo loo habayn karo moduleka: akhri xuduudaha SPD. Runtii, haddii kumbuyuutarka caadiga ahi akhriyo xogta SPD oo uu habeeyo kontaroolaha isaga oo ku saleysan, aan ka jarno xogtan netbook-ka jira oo aan galno miis.
Tan waxaa lagu sameeyaa Ubuntu : waxaad u baahan tahay inaad rakibto xirmada i2c-tools, modules load eeprom и i2c-i801 (Ma hubo, si kastaba ha ahaatee, in darawalka labaad uu ka shaqeyn doono meel kasta), ka dibna orod decode-dimms:

Xaaladdan oo kale, qoraalka ku qoran chips xusuusta laftooda ayaa aad u xiiso badan: K4T1G164QQ-HCF7. Markaad ku qorto xariiqan Google, waxaan helnaa xaashida xogta dhowr iyo toban bog oo leh dhammaan xuduudaha lagama maarmaanka ah, kuwaas oo si habsami leh loogu dari karo guryaha IP Core. Kaliya fiiro gaar ah u yeelo halbeegyada cabbirka: meel ns, meel - ps, iyo mararka qaarkood xitaa la wadaago tCK. Kuma bari doono waxa aad fiiro gaar ah u leedahay - Waxyaabo badan ayaan isku habeeyey si aan kala sooc lahayn (ma dammaanad qaadi karo inaadan "gubi karin" xusuusta ama FPGA sidan). Kaliya waxaan ku soo jeedin doonaa dareenkaaga tan: Ma heli karin kantarooluhu inuu shaqeeyo waqti aad u dheer, tallaabadii ugu dambeysayna waxay ahayd xaqiijinta inaan u baahday inaan hubiyo ballaca dhammaan is-dhexgalka xusuusta si aan ugu hoggaansamo koodhka Verilog ee la soo saaray. : ka dib oo dhan, marka la galay MemIfBundle tilmaamay val mem_ba = IO(Output(UInt(2.W))), oo waxaa jira bangiyada 8 (ie ciwaanka 3 balaastig ah), markaa dhammaanteen waxaan haysanaa wax soo saarka ka soo baxa kontoroolka xusuusta ee hawada ku dhegan - dhibaato, laakiin maaha mid muhiim ah, sidaas darteed wax walba waa la isku dhejiyaa, laakiin ma shaqeeyaan.
Waxaa laga yaabaa in wax walba ay la shaqeyn lahaayeen cutubkii hore haddii kantaroolaha la cusbooneysiiyo, laakiin hadda aad ayaan uga caajisay inaan wax ka qabto cayayaanka sabbeynaya: Waxaan haystaa ku filan aniga.

Hagaag, wax buu helay, malaha intaas ayaa ku filan. Xagee aaday konsole? Raadinta ayaa ku siinaysa xiriirinta arrinta Github: - waxaa soo baxday in UART keligiis, sida uu qabo darawalku, xitaa ma aha mid mudan in laga hadlo. Laakin ku taariikhaysan July 11, 2018 - hal sano ka hor. Waxa soo baxday in go'aankani aanu marnaba ka dhigin geedka aan ka dhisayo kernel-ka. Anigoo gacanta ku isticmaalaya balastarkan, waxaan helay Linux shaqeeya! Waxaa soo baxday in dhibaatada initramfs aysan runtii ahayn mid muhiim ah.
Gelitaanka sida isticmaale = xidid, furaha = sifive, waxaan awooday iyada oo aan wax dhibaato ah la kulmin (marka laga reebo fahamka in lambarka GPIO uu leeyahay saldhig, kaas oo wax walba laga xisaabiyo, oo kaliya u baahan in laga akhriyo faylka been abuurka ah) iyada oo loo marayo sysfs iftiimi LED-ka sabuuradda.
Sidii markii hore, waxaan ku lifaaqayaa muuqaal qoraal ah oo Linux ah oo bilaabaya. Marka konsole-ku ka wareego hore printk una wareego kan caadiga ah, nooc ka mid ah qashinka ayaa soo muuqda, oo la mid ah wax soo saarka marka xawaaraha UART si khaldan loo dejiyay. Waxa xiiso leh, ciyaartoygu wuxuu si guul leh uga soo shaqeeyay "khasab".
