Ubuntu/ZCU106
ZCU111と同じようにビルド．
スクリプト化した．https://github.com/miyo/build-zcu106-linux
あとは必要なものをSDカードに書くだけ．
- SDカードの用意
先頭に200MくらいのFAT領域，残りにext4領域を作る
FAT領域のタイプはc(W95 FAT32 (LBA))，ext4の方は83(Linux)にセットする．
で，
mkfs.vfat -F 32 -n boot /dev/sdX1 mkfs.ext4 -L root /dev/sdX2
などとしてフォーマット．Xのとこは自分の環境にあわせる．
- コピー
あとは，SDカードの先頭に作ったFATパーティションに ${WORK}/imageの中身をコピー．
二番目のパーティションにはQEMUで作ったルートパーティションを展開
- USB-UART
Linuxだと/dev/ttyUSB{0,1,2,3}が見える．/dev/ttyUSB0に接続する．
(ZCU111は/dev/ttyUSB1だったので注意)
rftoolをビルドしてみよう
petalinuxなプロジェクトからrftoolを実機にコピーしてビルドしてみることに
- "rfdc.h"を求められるので<rfdc.h>に書き変え
- rfdcのヘッダファイルを/usr/local/include/rfdcにコピー
- Makefileに CFLAGS = -I/usr/local/include/rfdc
を追加．これで，とりあえずビルドはできた．
fpgautilがない
rftoolを動かしてみようとおもったら fpgautil がなかった．
git clone https://github.com/Xilinx/meta-xilinx-tools.git
で，
cd meta-xilinx-tools/recipes-bsp/fpga-manager-script/files make fpgautil
でよかった．
