Op der Foto schéckt de Linux Kernel Gréiss un Iech iwwer GPIO.
An dësem Deel vun der Geschicht fir de RISC-V RocketChip op e chinesesche Bord mat Cyclone IV ze portéieren, wäerte mir nach ëmmer Linux lafen, a léiere wéi Dir den IP Core Memory Controller selwer konfiguréieren an d'DTS Beschreiwung vun der Ausrüstung liicht änneren. Dësen Artikel ass eng Fortsetzung , awer, am Géigesaz zu der zimlech extensiv virdrun, wäert et zimlech kuerz sinn.
... Well de setup_smp nëmmen genannt wann de Kernel mat SMP Support konfiguréiert ass, kënnt Dir probéieren Multi-Core auszeschalten. Et wäert désagréabel sinn wann ech och Atomicitéit Ënnerstëtzung am Memory Modul ëmsetzen muss (et huet mir geschéngt, datt de Cache eleng domatter klappt), awer am Single-Core Fall sollt et eis net stéieren.
Nach ëmmer net erofgaang ...

...Et ass interessant datt ech no all Debugging decidéiert hunn ze kucken wéi de "Referenz" Kerneloutput soll ausgesinn, sot hien make qemu, an hunn en ähnleche Feeler gesinn.
Och, den nächsten Niveau (Linux Kernel) ass méi komplizéiert: GDB, verbonne iwwer JTAG mam RocketChip, funktionnéiert anscheinend mat kierperlechen Adressen egal wéi de MMU konfiguréiert ass, an de Kernel am Moment wou mir interesséiert sinn huet den Display scho konfiguréiert vun Adressen, also ass et einfach ze soen display/10i $pc et wäert net schaffen - mir wäerten nëmme vill gesinn unimp. Awer wa mir de Offset schonn erausfonnt hunn (et schéngt dat 0x80200000 -> 0xffffffe000000000), da kënnt Dir fuddelen:

Backtrace stopped: frame did not save the PCAwer Dir musst se manuell ewechhuelen fir weiderzekommen - fir GDB ass dëst eng Aart vu komplett onverständlecher Fal. Oh jo, wann Dir geschitt ze soen s oder n anstatt si, gdb wäert probéieren en impliziten Breakpoint anzeginn, deen aus offensichtleche Grënn net gesat gëtt, awer et gëtt kee Wee fir GDB ofzehalen. Awer net presséiert fir de Board nei ze starten - no menge Beobachtungen ass et genuch fir nëmmen gdb nei ze starten (notéiert datt déi al Breakpunkter net verschwannen kënnen).
Eigentlech musst Dir mat dem urspréngleche Problem këmmeren: d'Placement vum Debugging printk an eng Funktioun of_find_node_by_type, benotzt vum Bootprozessor Kernel Sichcode, weist datt et eng Aart vu Gerempels gesäit anstatt Apparat Typ Nimm. Zum Beispill hëlt et d'Linn "Serial port" vun iergendwou, obwuel dëst kloer net am dtb Feld ass device_type. Nodeems ech dës Bytes am Kärelbild gesicht hunn, hunn ech se fonnt, de Offset gekuckt an dat offensichtlech realiséiert: d'Gréisst vum Kernel an de Bootparameter ass kloer ënnerschat: et gëtt 8Mb zougewisen, awer et hëlt méi wéi zéng. Ech hunn 16Mb zougedeelt, awer d'Fräiheet huet net opgehalen. Nom Danz mam FDT vu verschiddenen Adressen ze liesen (normalerweis gëtt d'Adress an de Kärel am Register transferéiert a1), Ech decidéiert endlech ze verfollegen, mee wat сейчас et gëtt do parséiert. Glécklecherweis, amplaz mat engem Debugger ronderëm ze goen (a mir erënneren datt et Nuancen mat Adressiwwersetzung sinn, déi nach ëmmer op eng oder aner Manéier geléist ginn), kënnt Dir einfach an d'Datei kräischen drivers/of/fdt.c uginn #define pr_debug printk.

Wärend dem Debuggingprozess hunn ech gemierkt datt BBL d'"duebel" Adress net liese konnt, net well et e Feeler an der Configuratioun war, awer einfach well de Root Node de #address-cells = <1>; #size-cells = <1>;.
D'Debug-Ausgab ausbauen, hunn ech gesinn datt d'Indikatoren op type и name "geschloen", an op eng zimlech komesch Manéier: hiren éischten (vun Null ufänkt) Byte gouf op Null zréckgesat, eppes wéi 0xabcdef -> 0xab00ef. Ech hu missen eng vertraute Taktik benotzen: d'Adressen kennen wou d'beschiedegt Erënnerung läit, füügt et un d'Funktioun printk Drécken dës Donnéeën. Gutt, d'Erausfuerderunge selwer printk verspreet se wou et wéineg vun hinnen sinn. Och, et ass net vill méi kloer ginn. Dunn hunn ech ugefaang, d'Demontéiert ze konsultéieren objdump Versioun, manuell Breakpunkte setzen an duerch déi problematesch Sektioun vum Code Schrëtt fir Schrëtt goen. An da gouf eng mysteriéis an onsympathesch Saach entdeckt: wann ech direkt e Breakpoint iergendwou relativ wäit vum bekannte gudden Zoustand setzen, da wäert ech ophalen, déi scho beschiedegt Erënnerung gesinn. Awer wann Dir probéiert roueg op hir Schrëtt fir Schrëtt ze schlecken, da bréngt de Käfer et fäerdeg ze verstoppen! Et richt wéi e futtis Memory Controller a Cache, deen de Feeler verstoppt wann Dir dauernd den erfuerderleche Wäert freet. Wat wier wann…
Ersetzen Erënnerung
Kleeft un d'Geleeënheet fir e Problem ze léisen deen net op menger Säit war, hunn ech ugeholl datt ech vläicht just e futtis Memory Stick kritt hunn. Dunn hunn ech erënnert datt en zéng Joer ale Netbook net nëmmen e portable Computer ass, awer och eng wäertvoll Quell vun DDR2 SO-DIMM. Als Bonus kënnt Dir d'Erënnerung aus dem Board erofhuelen an de Memtest bal direkt hänken (Linux, iwwregens, bal op d'grafesch Shell gelueden. Awer et ass besser dëst Experiment net ze widderhuelen wann Dir d'Informatioun op montéierten Disken schätzt ...). Engersäits kënne mir dovun ausgoen datt d'Erënnerung einfach net un dësem speziellen Netbook gepasst huet. Op der anerer Säit konnt hien booten! Et war Hoffnung datt d'Erënnerung einfach "gebrach" war, an de Problem war net a mengem Wrapper.
Dëst bedeit datt Dir musst probéieren temporär mat Netbook Memory ze starten. Leider weess Quartus 18 net wéi een dësen IP Core upgradéiert fir datt et geännert ka ginn. Dëst bedeit datt d'Zäit endlech komm ass fir ze léieren wéi een nei Instanzen erstellt. Alles huet sech ganz einfach erausgestallt: mir kucken am IP Katalog fir den Artikel DDR2 SDRAM Controller mat ALTMEMPHY Intel FPGA IP a mir kréien e Block mat der selwechter Interface wéi virdrun. Deen eenzege Problem ass déi richteg Erënnerung Astellungen.
Kréien d'Parameteren vun der Erënnerung Modul
Et gëtt e relativ offensichtleche Wee fir de Modul ze konfiguréieren: liesen d'Parameteren aus der SPD. Tatsächlech, wann e gewéinleche Computer SPD Daten liest an de Controller op der Basis konfiguréiert, da loosst eis dës Donnéeën op engem existente Netbook subtrahéieren an an en Dësch aginn.
Dëst gëtt op Ubuntu gemaach : Dir musst de Package installéieren i2c-tools, Luede Moduler eeprom и i2c-i801 (Ech sinn awer net sécher datt den zweete Chauffer iwwerall funktionnéiert), da lafen decode-dimms:

Wat ass op eise Moduler geschriwwen:
An dësem Fall ass d'Inscriptioun op de Memory Chips selwer méi interessant: K4T1G164QQ-HCF7. Andeems Dir dës Zeil op Google tippt, kréie mir en Dateblatt vun e puer Dutzend Säiten mat all déi néideg Parameteren, déi an den IP Core Properties ordentlech agefouert kënne ginn. Opgepasst just op d'Moosseenheeten: iergendwou ns, iergendwou - ps, an heiansdo souguer deelt tCK. Ech wäert Iech net léieren op wat Dir oppassen sollt - ech hunn vill Saache selwer zoufälleg konfiguréiert (ech kann net garantéieren datt Dir d'Erënnerung oder d'FPGA op dës Manéier net "verbrenne" kann). Ech wäert just Är Opmierksamkeet op dëst zéien: Ech konnt de Controller net fir eng ganz laang Zäit schaffen, an de leschte Schrëtt war d'Realiséierung datt ech d'Breet vun all Memory-Interfaces fir d'Konformitéit mam generéierte Verilog Code muss kontrolléieren : schliisslech, wann an MemIfBundle uginn val mem_ba = IO(Output(UInt(2.W))), an et sinn 8 Banken (dh eng Adress 3 Bits breet), dann ass alles wat mir hunn ass den Ausgang vum Memory Controller an der Loft hänkt - e Problem, awer net kritesch, also ass alles synthetiséiert, awer funktionnéiert net.
Vläicht géif alles mam ale Modul funktionnéieren wann de Controller aktualiséiert gëtt, awer fir de Moment sinn ech ze faul fir mat potenziellen schwiewend Bugs ze këmmeren: Ech hu genuch vu mengem eegenen.
Also, nom Plënneren timebase-frequency an DTS vum spezifesche CPU-Niveau op den Node-Niveau cpus (no der ganz verständlecher Ufro vum Kernel), kréie mir:

Okay, hien huet eppes fonnt, vläicht geet dat duer. Wou ass d'Konsol hin? D'Sich gëtt e Link zum Thema op Github: - et stellt sech eraus datt UART eleng, laut dem Chauffeur, net emol wäert ze schwätzen ass. Mee vum 11. Juli 2018 - virun engem Joer. Et huet sech erausgestallt datt dëst Engagement ni an de Bam gemaach huet, aus deem ech de Kärel bauen. Andeems Dir dëse Patch manuell applizéiert, krut ech e schaffende Linux! Et huet sech erausgestallt datt de Problem mat Initramfs wierklech net kritesch war.
Aloggen als Benotzer = root, Passwuert = sifive, Ech konnt ouni Problemer (ausser Versteesdemech, datt d'GPIO Nummer eng Basis huet, aus där alles berechent ass, an déi just aus dem entspriechende Pseudo-Fichier gelies muss ginn) duerch sysfs Luucht d'LED op de Bord.
Wéi déi lescht Kéier, befestegt ech en Textvideo vu Linux lancéiert. Wann d'Konsole vun earlyprintk op de Standard wiesselt, erschéngt eng Aart vu Gerempels, ähnlech wéi d'Ausgab wann d'UART Geschwindegkeet falsch agestallt ass. Spannen, huet de Spiller erfollegräich duerch dës "Mess" geschafft.
