適用平臺(tái)
Vivado和PetaLinux 2019.2。
Zynq UltraScale+ RFSoC ZCU111評(píng)估板
啟動(dòng)模式:JTAG,SD
模塊框圖
Vivado步驟
步驟1:基于ZCU111評(píng)估版創(chuàng)建一個(gè)工程,并根據(jù)上圖中的模塊設(shè)計(jì)完成相應(yīng)的模塊設(shè)計(jì)。
步驟2:按下列設(shè)置來(lái)配置AXI CDMA:
步驟3:成功完成后,選擇“驗(yàn)證設(shè)計(jì)(Validate design)”以驗(yàn)證設(shè)計(jì),并檢查地址編輯器。
步驟4:創(chuàng)建整個(gè)模塊設(shè)計(jì)的頂層文件并生成比特流。
步驟5:導(dǎo)出硬件設(shè)計(jì)以獲取XSA文件。
PetaLinux步驟
以下步驟用于生成啟動(dòng)鏡像和Linux用戶空間應(yīng)用。
步驟1:
使用以下命令和隨附內(nèi)容(axicdma.c)創(chuàng)建AXI CDMA用戶空間應(yīng)用。
vim axicmda.c
步驟2:
petalinux-create -t project -n bram --template zynqMP
步驟3:
petalinux-config --v --get-hw-description=
步驟4:
在system-user.dtsi文件中添加以下更改以禁用CDMA驅(qū)動(dòng)并保留內(nèi)存。
/include/"system-conf.dtsi" /{ #address-cells=<2>; #size-cells=<2>; memory{ device_type="memory"; reg=<0x0?0x0?0x0?0x80000000>,<0x0?0xA0000000?0x0?0x40000>,<0x00000008?0x00000000?0x0?0x80000000>; }; reserved-memory{ ranges; reserved{ reg=<0x0?0xa0000000?0x0?0x40000>; }; }; }; &axi_bram_ctrl_1{ status="disabled"; }; &axi_cdma_0{ status="disabled"; };
步驟5:
petalinux-config -c kernel
然后,按如下方式操作:
Kernel hacking --->[ ] Filter access to /dev/mem --> Save & exit
步驟6:
petalinux-build
步驟7:
petalinux-package --boot --fsbl images/linux/zynqmp_fsbl.elf --pmufw images/linux/pmufw.elf --fpga images/linux/system.bit --u-boot images/linux/u-boot.elf --force
步驟8:
將BOOT.bin和image.ub文件與測(cè)試應(yīng)用二進(jìn)制文件一起復(fù)制到SD卡。
步驟9:
啟動(dòng)評(píng)估板,并運(yùn)行隨附的應(yīng)用(axicmda.c)。
運(yùn)行設(shè)計(jì)
要運(yùn)行設(shè)計(jì),請(qǐng)首先連接到ZCU111評(píng)估板并從SD卡啟動(dòng)鏡像,然后運(yùn)行二進(jìn)制應(yīng)用文件。
