P\u00e4rast Linuxi portimist Sega MegaDrive'ile v\u00f5imaldati Linuxi kerneli k\u00e4ivitamist Busybox utiliitide komplektiga m\u00e4ngukonsoolil Atari Jaguar, mis ilmus 1993. aastal. Seade oli varustatud CPU Motorola 68000, millel oli 2 MB RAM ja millel v\u00f5is pideva salvestusena kasutada kuni 6 MB m\u00e4luga kartrid\u017ee. Seade oli varustatud kahe kooprotsessoriga: Tom (GPU, millel on 32-bitine RISC arhitektuur + 64-bitine video t\u00f6\u00f6tlemise protsessor + 64-bitine loogiliste operatsioonide protsessor) ja Jerry (DSP, millel on 32-bitine RISC arhitektuur, et hallata heli). <\/p>\n

Sarnaselt Sega MegaDrive sadamale, mis v\u00f5imaldab Linuxi kerne t\u00f6\u00f6tada Motorola 68000 CPU-l, millel puudub m\u00e4lu juhtimise riistvara (MMU), on tavaline kernel 7.2.0-rc1 kokku pandud mikrokontrollerite re\u017eiimis «NOMMU», mis v\u00f5imaldab kasutada tasapinnalist m\u00e4lumudelit lineaarse aadressiruumiga (varem arendusi MMU vabaks t\u00f6\u00f6ks viidi l\u00e4bi uClinuxi kerneli forkis, kuid seej\u00e4rel v\u00f5eti need p\u00f5hi kernelisse «NOMMU» variandina). Probleem ebapiisava juhatuse m\u00e4luga lahendati teistmoodi, kaasates execute-in-place (XIP) mehhanismi, mis v\u00f5imaldab otse k\u00e4ivitada kerneli koodi ROM-ist ilma RAM-i kopeerimiseta. <\/p>\n

Seadm\u00e4luseadmes on RAM aadressil 0x000000, samas kui ROM (kartrid\u017e) on aadressil 0x80000. Seet\u00f5ttu on Linuxi tuuma komponendid jaotatud kaheks eraldi m\u00e4lualaks: sektsioonid .rodata ja .text, kus on konstantsed andmed ja kood, on paigutatud kartrid\u017eile, ning sektsioonid .data ja .bss, kus on muudetavad andmed, on RAM-is. Kuna CPU 68000 otsib katkestustabelit aadressilt 0x0, kuid tuum asub tegelikult kartrid\u017eis, mille sisu peegeldub aadressil 0x80000, kasutati lisaks katkestustabelite kopeerimise haki RAM-i. <\/p>\n

Probleem, et Motorola 68000 CPU-l puudus ajastustihend, lahendati DSP-s kasutatavate ajastite kaasamisega helis\u00fcntesis. Need ajastid kasutati katkestuste genereerimiseks \u00fclesande planeerija aktiveerimiseks. S\u00fcdamiku s\u00f5numite edastamiseks laadimise ajal kirjutati eraldi konsooldraiver, mis simuleeris paralleelporti SID-d ja RXD v\u00e4ljundite kaudu, mida juhtis DSP-protsessor. <\/p>\n

Kasutajaruumi komponentide kokku panemiseks kasutati Buildrooti t\u00f6\u00f6riistakomplekti koos LinuxMD projekti plaastritega. M\u00e4lu kokkuhoiu nimel kutsuti algselt v\u00e4lja k\u00e4surea kest '\/bin\/busybox sh', funktsioon malloc uClibc teegis asendati lihtsustatud versiooniga malloc-simple, mis ei s\u00e4ilitanud t\u00e4iendavaid metaandmeid, ning t\u00e4ieliku laadija, n\u00e4iteks U-Boot, asemel tehti tuumale otse\u00fclekanne k\u00e4suga 'jmp $80000'.
