RISC-Vネタ続き。今度も支那製のRISC-VベースのSBCで名前が示す通り、RaspberryPiフォームファクター互換（と言って良いのか）、具体的にはRPi zeroフォームファクタ互換風なRISC-VベースのLinux SBC。：
外観はこちら↓
下手な写真で申し訳ないが下のピンクの基板がMQ-pro（MangoPi proとも）で、上のさつま芋色（語彙が貧相ですみません：）基板は下にMQ-proがあってUSB-serial変換他を兼ねるRPI zero用のMaker pHATになる。pHATが登場するのはMQ-proがRPI zeroフォームファクタ互換（少なくとも拡張バスの主用な接続、今回はシリアルと電源、GND系が合っていれば使えそうなので）に見えたので使ってみた。開発者がフォームファクタ互換にする理由はオリジナルの周辺機器を流用したのも理由だから当然と言えば当然とも言える。私にとっての興味の中心は支那製RISC-V64Socの情報取得なので、Allwinner（センスが・・・、でも各種機器に採用されている有名なプランドではある：）最低限のブロック図をデータシートから引用：
0.Allwinner D1-H The RISC-V Multi-Media Decoding Platform SoC
雑な比較だが巷に色々提供されているアプリケーションプロセサ（古いが使った事があるチップという意味でFreescale i.MX515(Singlecoreという意味で：）等の所謂ARM cortex-A系のSocのRISC-V64版というイメージだろうか。これは他社：例えばRenesas）も同様でARM v8コア版とRISC-V64 or 32版というアプローチに見える（RISC-V純血派以外は：）。きっとこれはユーザに少ないリスクでマイグレーションパスを提案出来るメーカの戦術なのだろう（古くはFreescaleのMCF51JM/MS9S08JMとか）。もっともこの手の頭替え戦術は成功事例は少ない様な気がするし、ポイントは異なるアーキテクチャコアに最も抵抗するのはソフト屋さんだから、それをねじ伏せる権力以外の方法があるか、具体的にはRISC-V64ならではのキラーアプリケーションを創出出来るかがRISC-Vワールドの未来を握っているのだろう。日本人としてはRenesasさんのRISC-V64のLinuxBSP対応のエバボードが個人入手可能なレンジで提供されると嬉しいな（願望）。
それはさておき、
1.MangoPiについて
正直よく知らないので上記本家サイトを参照。もっともRPI財団の如く整った体制ではなさそうで（素材の関係から支那系技術者が主体？）それはそれでこういう界隈はそういうものであろう。少なくともOx64のUndocumented状態（言い過ぎです：）に比べりゃ雲泥の差、というか少なくともマイクロSDカードに適切なイメージファイルをddすればシリアルコンソールにメッセージが出力される。
MQ-proの本家サイトだが、コンテンツはこれからの様でバカでかい写真で大半の空間を埋めている。肝心のハードウェア資料は回路図とBOMデータはUpされており、Socのデータシートとマニュアルも存在する（英語版も：）。上記のRPi用pHATが使えるか判断する為に回路図を確認しておく：
上図中右がRPi互換と思しき拡張コネクタでざっとピン情報をRPiのそれと突き合わせると少なくともconsole用TXD,RXD,GND、電源系は互換に見えるし、GPIOは全く異なるがそれはマッピングするなり開発元の情報を参照すれば良い訳で、少なくともRPi用pHATを接続可能かと言えば・・・何とかなるのではというのが私の判断。ああ、コンソールシリアルが動けばいいやという意味です：）。
RPi用のpHATが使える前提で後はMQ-proとpHATを接続する為にピンヘッダをハンダ付けする（ハンダセラピーとも：）。それが上記写真の下のピンク基板のピンヘッダハンダ付け済のMQ-proなのです。ああハンダセラピーとはプロセッサ誌かトラ技かどこかで久しくハンダゴテを握っていない変人さんが禁断症状や多種多様なストレスに苛まれた時に、人が癒やしグッズや小動物によるセラピーのハンダ付けバージョンと称して言われたスラングです。今の境遇の私には染み入る言葉かもしれない（単なる妄想です：）。ハードウェアの準備は後はマイクロBケーブルを用意すれば良いだけで、RPi zeroスキームを流用出来れば楽に済む筈。。。
２．Armbian
RISC-VターゲットなのにARM風な名前のディストリなのは歴史的経緯があるのだろう。さまざまなディストリが存在する様だが本家サイトで開示されており、中国語では無い物からArmbian 22.08のディストリを探してきた。本家サイトはGUIベースの為、コンソールにはBootシーケンスを出力するがコンソールとして使えないので能無し（headless)バージョンをGoogleさんに探してもらう：
私が書き込んだのはHeadlessバージョンで上記サイトから：
Headless / CLI
Armbian_22.08.0-trunk_Nezha_jammy_current_5.19.0.img.xz
Armbian_22.08.0-trunk_Nezha_sid_current_5.19.0.img.xz
リンク先がロシアなのが不安。。。
３．起動
ディスクイメージの書込はxzを解凍し、imgファイルをddでマイクロSDに書込、MQ-proのマイクロSDスロットに挿して、pHATのUSBケーブルをUbuntu２０．０４（Thinkpad A285)に接続し、gtktermでボーレートを115,200bpsに設定し、電源Onすると普通にbootしてくれる。操作感はRPi zeroと同様な印象

数年前にRISC-VのISA本を斜め読みした気はするが命令セットは自分で使い込んでみないと身につかないもので記憶に薄いが、偏見ありまくりの見方（これでもRISC-V支持派故、RISC/CISC等という差別語（意識高い系の人、IT業界はMaster/Slave型Flip−Flop等、人権に配慮しない差別語（彼らにとっては＝差別主義者であり、敵：）に満ち溢れておりますぞ、活動を（煽り）：）を撒き散らす御大の思考回路はどうかと思うのだが、それはそれとして（技術に色は付いてないので）普通の人間でも理解しやすく、簡潔で好印象な命令・コード出力との印象を示しておこう。
