Ubuntu/ZCU111の続き

- U-bootで自動的に起動するようにする
uEnv.txtじゃなくてboot.scrを使う．手で入力してたコマンドを boot.script に保存．
fatload mmc 0 0x10000000 Image fatload mmc 0 0x02a00000 zynqmp-zcu111-revA.dtb setenv bootargs earlycon clk_ignore_unused consoleblank=0 root=/dev/mmcblk0p2 rootfstype=ext4 rw rootwait booti 0x10000000 - 0x02a00000
で，
$ ${WORK}/u-boot-xlnx/tools/mkimage -A arm64 -O linux -T script -C none -a 0 -e 0 -n "boot.scr" -d boot.script boot.scr
として boot.scr を作る．これを BOOT.binとか置いたパーティションにコピー．
- PLの再コンフィギュレーション
これは，ZYNQでやってたときと同じ．
fpga.dtsを用意して
/dts-v1/;
/ {
fragment@0 {
target-path = "/fpga-full";
__overlay__ {
firmware-name = "fpga.bin";
};
};
};
dtcでdtsからdtbを作成
dtc -I dts -O dtb -o fpga.dtb fpga.dts
fpga-bit2bin.pyでbitファイルからbinファイルを作って，
/lib/firmware/fpga.bin に配置して
mkdir -p /sys/kernel/config/device-tree/overlays/fpga cp fpga.dtb /sys/kernel/config/device-tree/overlays/fpga/dtbo
- RFdcアプリの実装のためにライブラリの準備
実機で作業してしまう
https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/84378586/Building+RFDC+application+from+git+sources+for+ZCU111 ベースにしつつ，実機なのでちょっと違う
libsysfs-devやcmakeやらが必要らしいのでaptでインストール
sudo apt install libsysfs-dev cmake
一式を取得．ホームディレクトリの下で作業する．
cd ~/ git clone https://github.com/Xilinx/embeddedsw cd embeddedsw git checkout xilinx-v2019.1
libmetalのビルド
cd ThirdParty/sw_services/libmetal/src/libmetal mkdir build_libm; cd build_libm cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake/platforms/zynqmp-linux.cmake make -k sudo make install/fast
test関連のソースのビルドでエラーがでるので，ごにょごにょとスキップ．
cd ~/embeddedsw/XilinxProcessorIPLib/drivers/rfdc/src/ make -f Makefile.Linux
- RFdcのサンプルを動かしてみる，が．
user@zcu111:~/embeddedsw/XilinxProcessorIPLib/drivers/rfdc/examples$ ./rfdc-read-write RFdc Read and Write Example Test metal_sys_init success: sysfs_get_mnt_path success: fopen /dev/urandom success: metal_init_page_sizes try: metal_linux_bus_init metal_linux_bus_init metal_linux_probe_bus try: sysfs_open_bus: platform success: sysfs_open_bus: platform try: metal_linux_probe_driver metal_linux_probe_driver try: sysfs_open_driver platform uio_pdrv_genirq result: sysfs_open_driver (nil) metal_linux_probe_driver try: sysfs_open_driver platform uio_dmem_genirq result: sysfs_open_driver (nil) error: metal_linux_probe_driver metal_linux_probe_bus try: sysfs_open_bus: pci success: sysfs_open_bus: pci try: metal_linux_probe_driver metal_linux_probe_driver try: sysfs_open_driver pci vfio-pci result: sysfs_open_driver (nil) metal_linux_probe_driver try: sysfs_open_driver pci uio_pci_generic result: sysfs_open_driver (nil) error: metal_linux_probe_driver ERROR: Failed to run metal initialization Read and Write Example Test failed user@zcu111:~/embeddedsw/XilinxProcessorIPLib/drivers/rfdc/examples$
って感じでmetal_initで失敗．
ちなみにTRDで実行してみると

とか
ためしにTRDでsys以下をfindしてみると
root@xilinx-zcu111-2020_2:/sys# find . -name \*uio\* -print ./class/uio ./class/uio/uio1 ./class/uio/uio4 ./class/uio/uio2 ./class/uio/uio0 ./class/uio/uio3 ./devices/platform/amba/fd0b0000.perf-monitor/uio ./devices/platform/amba/fd0b0000.perf-monitor/uio/uio1 ./devices/platform/amba/fd490000.perf-monitor/uio ./devices/platform/amba/fd490000.perf-monitor/uio/uio2 ./devices/platform/amba/ffa00000.perf-monitor/uio ./devices/platform/amba/ffa00000.perf-monitor/uio/uio0 ./devices/platform/amba/b0010000.axi_perf_mon/uio ./devices/platform/amba/b0010000.axi_perf_mon/uio/uio4 ./devices/platform/amba/ffa10000.perf-monitor/uio ./devices/platform/amba/ffa10000.perf-monitor/uio/uio3 ./bus/platform/drivers/uio_pdrv_genirq ./bus/platform/drivers/uio_dmem_genirq ./module/uio_xilinx_ai_engine root@xilinx-zcu111-2020_2:/sys# find . -name \*pci\* -print ./kernel/debug/clk/pcie_ref_mux ./kernel/debug/clk/pcie_ref_div1 ./kernel/debug/clk/pcie_ref ./class/pci_bus ./bus/platform/drivers/xilinx-pcie ./bus/platform/drivers/xilinx-xdma-pcie ./bus/platform/drivers/nwl-pcie ./bus/pci ./bus/pci/drivers/ps_pcie_dma ./firmware/devicetree/base/amba/pcie@fd0e0000 ./firmware/devicetree/base/__symbols__/pcie ./firmware/devicetree/base/__symbols__/pcie_intc ./module/edac_core/parameters/edac_pci_panic_on_pe ./module/edac_core/parameters/check_pci_errors
で，自分でセットアップした方は，
root@zcu111:/sys# find . -name \*uio\* -print ./class/uio ./class/uio/uio1 ./class/uio/uio2 ./class/uio/uio0 ./class/uio/uio3 ./devices/platform/amba/fd0b0000.perf-monitor/uio ./devices/platform/amba/fd0b0000.perf-monitor/uio/uio1 ./devices/platform/amba/fd490000.perf-monitor/uio ./devices/platform/amba/fd490000.perf-monitor/uio/uio2 ./devices/platform/amba/ffa00000.perf-monitor/uio ./devices/platform/amba/ffa00000.perf-monitor/uio/uio0 ./devices/platform/amba/ffa10000.perf-monitor/uio ./devices/platform/amba/ffa10000.perf-monitor/uio/uio3 root@zcu111:/sys# find . -name \*pci\* -print ./kernel/debug/clk/pcie_ref_mux ./kernel/debug/clk/pcie_ref_div1 ./kernel/debug/clk/pcie_ref ./class/pci_bus ./bus/platform/drivers/nwl-pcie ./bus/pci ./firmware/devicetree/base/amba/pcie@fd0e0000 ./module/edac_core/parameters/edac_pci_panic_on_pe ./module/edac_core/parameters/check_pci_errors root@zcu111:/sys#
たしかに，uio_pdrv_genirqやuio_dmem_genirqがいない．
Linuxの.configをみると，
CONFIG_UIO_PDRV_GENIRQ=m CONFIG_DMEM_GENIRQ=m
だったので，
CONFIG_UIO_PDRV_GENIRQ=y CONFIG_DMEM_GENIRQ=y
にしてビルド。
/sys/bus/platform/drivers/uio_pdrv_genirq /sys/bus/platform/drivers/uio_dmem_genirq
がはえた．というわけで再実行．

とりあえず，metal_initは通ったよう．
Invalid device id 0Read and Write Example Test failed
は，DACやADCのエントリがないから仕方ない気がする(次の仕事だと思う)．
ちょっとlibmetalを分かってからじゃないと次すすめないな．
