本篇博文將為您演示如何創(chuàng)建 AXI CDMA Linux 用戶(hù)空間示例應(yīng)用。
示例設(shè)計(jì)將在 Zynq UltraScale+ RFSoC ZCU111 評(píng)估板上實(shí)現(xiàn)通過(guò) AXI CDMA 把數(shù)據(jù)從 PS DDR 傳輸至 AXI BRAM。
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(hù)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(hù)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。
