實(shí)驗(yàn)?zāi)康模涸贒E10-Standard 下通過HPS控制FPGA實(shí)現(xiàn)流水燈
實(shí)驗(yàn)環(huán)境：
Quartus15.0-Lite
Soc EDS 17.0 (DS-5部分若需使用需付費(fèi))
Win32DiskImager
參考手冊(cè)：
DE10官方手冊(cè)（DE10-Standard_v.1.2.4_SystemCD\Manual）
DE10-Standard Getting Started Guide
DE10-Standard User Manual Chapter 7
第一步：打開FPGA例程，修改引腳
位置：DE10-Standard_v.1.2.4_SystemCD\Demonstration\SoC_FPGA\DE10_Standard_GHRD
1.打開Quartus->File->Open Project->定位到官方例程的位置選擇qpf文件打開工程
2.點(diǎn)擊pin planner 根據(jù)新的開發(fā)板電路圖為 led0-led9重新分配引腳
具體引腳分配如上圖所示佩谣，綁定引腳過程中辜腺，若存在當(dāng)前引腳已分配页响，則刪除之前被綁定的部分志鞍，然后將引腳綁定到led上
3.編譯程序
4.編譯成功后燒錄程序
點(diǎn)擊program device
插上JTAG線，啟動(dòng)開發(fā)板電源优幸，選擇hardware setup
點(diǎn)擊auto detect 選擇型號(hào)
選擇生成的.sof文件燒錄
第二步編寫HPS程序
生成HPS頭文件
1.找到 sopc-create-header-files并把文件改為.sh文件
2.復(fù)制文件到FPGA工程下寂纪，并更改sopc-create-header-files的最后幾行的內(nèi)容
具體修改如下
cmd="sopcinfo2swinfo --input=$sopc_design_file --output=$swinfo_tmp_fname ${sopcinfo2swinfo_args[@]}"
/cygdrive/d/altera/15.0/quartus/sopc_builder/bin/sopcinfo2swinfo --input="$sopc_design_file" --output="$swinfo_tmp_fname" ${sopcinfo2swinfo_args[@]} || {
echo "$PN: $cmd failed"
exit 1
}
cmd="swinfo2header --swinfo $swinfo_tmp_fname --sopc $sopc_design_file ${swinfo2header_args[@]}"
/cygdrive/d/altera/15.0/quartus/sopc_builder/bin/swinfo2header --swinfo "$swinfo_tmp_fname" --sopc "$sopc_design_file" "${swinfo2header_args[@]}" || {
echo "$PN: $cmd failed"
exit 1
}
exit 0
3.打開SoCDES的shell，切到工程目錄下執(zhí)行
執(zhí)行如下語句夭织，便可在工程目錄下生成hps0.h文件
./sopc-create-header-files.sh soc_system.sopcinfo --single hps_0.h --module hps_0

打開SoCDES的shell切到.c文件所在的文件夾之后make即可生成可執(zhí)行文件
第三步吭露，將生成的可執(zhí)行文件拷貝到操作系統(tǒng)中運(yùn)行即可
