P\u00e4rast Linuxi portimist Sega MegaDrive'ile on rakendatud v\u00f5imalus k\u00e4ivitada Linuxi kernel koos Busyboxi utiliitide kogumikuga m\u00e4ngukonsoolil Atari Jaguar, mis ilmus 1993. aastal. Seade varustati CPU Motorola 68000-ga, sisaldas 2 MB RAM-i ja kasutati p\u00fcsivara salvestamiseks kuni 6 MB kaarte. Seade oli varustatud kahe kooperatiivprotsessoriga: Tom (GPU 32-bitise RISC-arhitektuuriga + 64-bitine videote t\u00f6\u00f6tlemise protsessor + 64-bitine loogilise t\u00f6\u00f6tluse protsessor) ja Jerry (DSP 32-bitise RISC-arhitektuuriga helit\u00f6\u00f6tluseks). <\/p>\n

Sarnaselt Sega MegaDrive sadamale, mis v\u00f5imaldab Linuxi tuuma k\u00e4ivitamist Motorola 68000 protsessoris, millel puudub riistvaraline m\u00e4lu haldamise moodul (MMU), on standardtuuma versioon 7.2.0-rc1 kompileeritud mikrokontrollerite re\u017eiimis \u201eNOMMU\u201c, mis v\u00f5imaldab kasutada lame m\u00e4lu mudelit sirgjoonelise aadressiruumiga (varasemalt oli ilma MMU t\u00f6\u00f6tamiseks arendatud lahendusi uClinuxi tuumaforkis, kuid need v\u00f5eti hiljem tuuma p\u00f5hiversioonile t\u00f6\u00f6tlusse valiku \u201eNOMMU\u201c vormis). Probleem, mis puudutab p\u00fcsiv\u00e4hem\u00e4lu puudumist, lahendati teisiti, kasutades meetodit execute-in-place (XIP), mis v\u00f5imaldab tuuma koodi otse ROM-ilt k\u00e4itada, ilma et see kopeeritaks operatiivm\u00e4lu. <\/p>\n

Seadmestiku RAM on peegeldatud aadressil 0x000000, samas kui ROM (kasset) \u2014 aadressil 0x80000, seega Linuxi tuuma komponendid on jagatud kaheks eraldi m\u00e4lupiirkonnaks: .rodata ja .text sektsioonid, mis sisaldavad konstantse ja koodi, on asetatud kassettile, samas kui .data ja .bss sektsioonid, mis sisaldavad muudetavaid andmeid, on operatiivm\u00e4les. Kuna CPU 68000 otsib katkestustabelit aadressilt 0x0, kuid tuuma tegelik asukoht on kassett, mille sisu peegeldub aadressil 0x80000, rakendati t\u00e4iendavalt h\u00e4kki, mille kohaselt kopeeriti katkestuse vektorid RAM-i. <\/p>\n

Probleem, mis seisnes ajasturi puudumises CPU Motorola 68000-s, lahendati DSP-s helis\u00fcnteesi jaoks kasutatavate ajastitega. Neid ajaste kasutati katkestuste genereerimiseks \u00fclesande ajakava aktiveerimiseks. Kerneliteadeteks laadimise ajal kirjutati eraldi konsoolidraiver, mis edastas andmeid paralleelse portaali simuleerimise kaudu, kasutades TXD ja RXD v\u00e4ljundeid, mida juhiti DSP-protsessori kaudu. <\/p>\n

Kasutaja ruumi komponentide koostamiseks kasutati Buildroot'i t\u00f6\u00f6riistu koos LinuxMD projekti plaastritega. M\u00e4lus\u00e4\u00e4stmise huvides kutsuti initsialiseerimise k\u00e4igus otse v\u00e4lja k\u00e4sklus \u201e\/bin\/busybox sh\u201c, malloc funktsioon uClibc raamatukogus asendati lihtsustatud versiooniga malloc-simple, mis ei hoia t\u00e4iendavaid metaandmeid, samas kui t\u00e4ie \u00f5iguslikku laadijat, nagu U-Boot, asendati tuuma otsek\u00e4ivitamisega k\u00e4suga \u201ejmp $80000\u201c.
