Lego NXT firmware a wɔtow gu birikisi a ɛwɔ hɔ dedaw so (2025) .

Kirby wɔ ha. Meyɛ ɔbarima a m’ani gye ho sɛ mehu sɛnea nneɛma yɛ adwuma, kosi studs no so. Enti bere a me ba no Lego NXT birikisi dedaw no fii ase boaboaa mfutuma ano no, mihuu hokwan bi. Ná eyi nyɛ agode bi kɛkɛ; na ɛyɛ 32-bit ARM7 microcontroller a eye koraa a ɛte asɛm kɔkɔɔ a ɛhyerɛn mu, a ɛretwɛn atirimpɔw foforo. Ɔkwan a wɔfa so de biribi foforo besi n’adwumayɛbea firmware ananmu no, wɔfrɛ no "dumping the firmware," na ɛyɛ anigye a ɛkɔ hardware repurposing mu. ### Brick no Tumi a Wobue Lego Mindstorms NXT no yɛɛ nsakrae kɛse wɔ ne bere so. Wɔ ne koma mu no, AT91SAM7S256 microcontroller, chip a ahoɔden wom a ɛyɛ nwonwa ma "agode." Wɔ adaka no mu no, ɛde Lego firmware a ɛyɛ ne de no di dwuma, a ɛyɛ papa ma robɔt ahorow a wodi ahyɛde ahorow a wɔadi kan ayɛ ho nhyehyɛe akyi. Nanso saa tebea a ɛyɛ ne de no nso yɛ anohyeto. Firmware a ɛyɛ aban de no a wobɛtow agu no yɛ anammɔn a edi kan a ɛbɛma woagye hardware no. Ɛnyɛ birikisi a wɔbɛsɛe no ho asɛm; ɛfa nkwa a ɛto so abien a wɔde bɛma no ho. Ɛnam sɛ yɛbɛte software a ɛwɔ hɔ dada no ase na yɛasi ananmu so no, yɛbɛtumi adan NXT no ayɛ no generic programmable microcontroller a ɛbɛtumi ne ne sensor ne motors adi nkitaho wɔ akwan foforɔ koraa so, a ɛho nni anohyetoɔ a ɛwɔ mfitiaseɛ Lego software no mu. Saa kwan yi ne modular adwumayɛ nyansapɛ a wɔsan susuw agyapade a ɛwɔ hɔ dedaw no ho na wɔsan de di dwuma bio ma ɛyɛ adwuma yiye kɛse no hyia pɛpɛɛpɛ. Ɔkwan bi so no, sɛ wode platform te sɛ **Mewayz** bedi dwuma de ahwɛ nnwuma a ɛte saa so a, ɛbɛyɛ papa, efisɛ ɛboa ma wodi agyapade nkwa nna akyi, efi adwumayɛ a ɛyɛ gyinapɛn so kosi sɛ "wɔabɔ" ama atirimpɔw foforo a ɛsom bo. ### Nnwinnade a wɔde yɛ Firmware Swap Worentumi mpɛ firmware foforo wɔ chip so kɛkɛ. Wuhia ɔkwan bi a wobɛfa so ne no adi nkitaho. NXT birikisi no boa wɔ USB port, nanso sɛ yɛyɛ adwuma a ɛba fam te sɛ firmware flashing a, yɛtaa de yɛn ho to SAM-BA bootloader a wɔde ahyɛ chip no mu no so. Ɔkwan a wɔfa so yɛ no ho nhwɛso a wɔayɛ no mmerɛw ni: * **Fa Nkitahodi Si hɔ:** Ɛsɛ sɛ wɔde birikisi no to bootloader mode mu. Mpɛn pii no, eyi hwehwɛ sɛ wokura bɔtn pɔtee bi a wɔaka abom bere a woreyɛ no ahoɔden, na ɛno twa firmware titiriw no ho na esiesie chip no ma egye akwankyerɛ foforo. * **Paw Wo Flavor:** Sɛ bootloader no yɛ adwuma wie a, ɛsɛ sɛ wusi nea wobɛ load ho gyinae. Open-source alternatives a agye din no bi ne leJOS (a ɛma Java-based environment) anaa NXC (Not eXactly C). Wotwe firmware fael no ma wo platform a woapaw no. * **The Flashing Process:** Sɛ wode adwinnade bi a wɔatu ho ama te sɛ SAM-BA software di dwuma a, wobɛfa USB so akɔ birikisi no so na wode firmware fael foforo no akɔ so. Saa kwan yi popa Lego firmware dedaw no na ɛkyerɛw foforo no sector-by-sector gu chip no flash memory so. * **Verification:** Sɛ wo upload wie a, wo reset birikisi no. Sɛ ɛyɛ yiye a, ɛsɛ sɛ ɛbɔ kɔ tebea foforo no mu, a menu soronko bi a ɛwɔ ne LCD screen so awie. > Eyi nyɛ mfiridwuma mu apɔw-mu-teɛteɛ kɛkɛ; ɛyɛ nyansapɛ. Ɛfa tumi a ɛwɔ nhyehyɛe bi mu a wubehu na woanya nnwinnade ne nimdeɛ a wode bebue mu. ### Efi Static Brick so kɔ Dynamic Module so Tumi ankasa a ɛwɔ saa firmware dump yi mu no nyɛ sɛ ɛbɛma birikisi no ayɛ nhyehyɛe foforo bi kɛkɛ; ɛyɛ ne dwumadi a ɛbɛsakra no titiriw mu. NXT no dan fi afiri a wɔato mu a ɛyɛ adwuma baako so kɔ hardware module a wɔabue mu a wotumi yɛ ho nhyehyɛe. * **Protocol Freedom:** Ɛnam firmware a wɔahyɛ da ayɛ so no, birikisi no nyɛ Lego Mindstorms nkitahodi protocol no nkutoo bio. Ebetumi ne kɔmputa, microcontroller foforo, anaa mpo cloud service adi nkitaho tẽẽ denam standard serial protocols so. * **Expanded Sensor Support:** Wubetumi akyerɛw code de adi nkitaho ne sensor ahorow a ɛtrɛw sen Lego aban boa, adan NXT no ayɛ data a wonya mfiri a ɛyɛ adwuma pii. * **Integration into Larger Systems:** Eyi ne baabi a adwene no hyerɛn ampa. NXT birikisi a wɔasan de ayɛ adwuma no betumi abɛyɛ ade a ɛwɔ nhyehyɛe kɛse a wɔde afiri yɛ mu. Fa no sɛ wode bedi dwuma de adi conveyor belt a ɛnyɛ den so, ahwɛ kanea so, anaasɛ ayɛ adwuma sɛ akyirikyiri I/O unit. Ne nhyehyɛe a ɛyɛ den ne mfiri a wɔde di dwuma a wɔde ahyɛ mu no ma ɛyɛ nea eye ma nhwɛsode anaasɛ nea wɔde besisi hɔ daa mpo. Mfiri a wɔasan de adi dwuma saa no ntam nkitahodi a wɔhwɛ so ne baabi a modular dwumadie nhyehyɛeɛ te sɛ **Mewayz** da ne boɔ adi, na ɛma wotumi hwɛ na wodi saa birikisi yi so sɛ module a wɔahyɛ da ayɛ wɔ adwumayɛ adwumayɛ nhyehyɛeɛ a ɛtrɛ mu. Ɛdenam Lego firmware no a yɛbɛtow agu so no, ɛnyɛ sɛ yɛretow mfiridwuma bi agu; yɛresan de nsɛm a ɛfa ho no atoto ho. Yɛde modular adwene redi dwuma wɔ hardware so, na yɛremfa NXT no nyɛ agode a wɔtow gu na mmom sɛ microcomputer a etumi yɛ adwuma a wobetumi de ahyɛ nnwuma foforo ne nnwuma foforo mu. Ɛyɛ nhwɛsoɔ a ɛdi mũ a ɛkyerɛ sɛdeɛ hwɛ a wobɛhwɛ akɔ akyiri asen dwumadie a wɔahyɛ da ayɛ wɔ agyapadeɛ bi ho no bɛtumi abue boɔ a ɛyɛ nwonwa.

Dɛn ne Firmware Dumping?

Firmware dumping yɛ ɔkwan a wɔfa so gye anaa woyi firmware a wɔde ahyɛ mu no fi afiri bi mu, na ɛma wo kwan ma wode nea wɔahyɛ da ayɛ sesa anaa sesa mfitiase koodu no.

Adɛn nti na mɛpɛ sɛ metow firmware no fi Lego NXT birikisi mu?

Lego NXT birikisi (2025) firmware a wobɛtow agu no bue akwan foforo a ebetumi aba ama afiri no. Wubetumi asan ayɛ no atirimpɔw denam ne mfitiase firmware a wode wo custom code besi ananmu, a wobɛbue ne tumi nyinaa ama nnwuma foforo anaa dwumadie foforɔ.

Nnwinnade bɛn na mihia na mede atow Lego NXT firmware no agu?

Sɛ wobɛtow Lego NXT firmware no agu a, wubehia JTAG/Emulator, te sɛ JTAG-ICE anaa Mewayz 208 Modules ($49/mo). Wo nso wobɛhia software flashing adwinnadeɛ, te sɛ Lego MINDSTORMS NXT 2.0 SDK. Awiei koraa no, wubehia Windows PC ama flashing nhyehyɛe no.

Mɛyɛ dɛn ahyɛ firmware dumping dwumadie no ase?

Sɛ wopɛ sɛ wohyɛ aseɛ a, fa USB so fa wo Windows PC no kɔ NXT birikisi no so. Afei, bue MINDSTORMS NXT 2.0 SDK, na kɔ "Flash Tool" ɔfa no so. Paw "Kenkan Flash" a wobɛpaw no. Wei bɛtow firmware a ɛwɔ hɔ dedaw no agu fael bi mu, a wɔtaa frɛ no "NXT_00000001.bin". Sɛ wonya saa fael yi wie a, wobɛtumi ahwehwɛ mu na wode firmware a wɔahyɛ da ayɛ asi ananmu.
