    How to find USB Flash in Petalinux running on ZYNQ HOST ??

    in Embedded Linux

    Posted

    Hi,

    Petalinux is running on ZYBO Z7-20. How to find the attached Flash USB drive ? I don't see USB Flash drive in /dev folder. The jumper JP2 USB Host is short on ZYBO Z7-20.

    The following steps have been taken in to account.

    1-     Created hardware project in Vivado 2021.1

    2-     Added ZYBO Z7-20 board

    3-     Added ZYNQ PS in Block Diagram

    4-     Apply board pre-set and run block automation

    5-     Validate design, Generated output products, HDL wrapper

    6-     Synthesis, Implementation, Generate bit stream

    7-     Export project with XSA file

    8-     Created Petalinux project with template command and set variable OE_TERMINAL = "xterm" in <plnx-proj-root>/project-spec/meta-user/conf/petalinuxbsp.conf 

    9- Manually edited system-user.dtsi

      

    /include/ "system-conf.dtsi"
/ {
 
	model = "Zynq Zybo Z7 Development Board";
	compatible = "digilent,zynq-zyboz7", "xlnx,zynq-7000";
 
	chosen {
		bootargs = "console=ttyPS0,115200 earlyprintk uio_pdrv_genirq.of_id=generic-uio";
	};
 
	usb_phy0: usb_phy@0 {
		compatible = "ulpi-phy";
		#phy-cells = <0>;
		reg = <0xe0002000 0x1000>;
		view-port = <0x0170>;
		drv-vbus;
	};
 
 
};
 
&gem0 {
	phy-handle = <&ethernet_phy>;
/*	phy-reset-gpio = <&axi_gpio_eth 0 0>;
	phy-reset-active-low;	
	phy-reset-duration = <10>; */
	ethernet_phy: ethernet-phy@1 { /* rtl8211e-vl */
		reg = <1>;
		device_type = "ethernet-phy";
	};
};
 
&usb0 {	
	dr_mode = "host";
	usb-phy = <&usb_phy0>;
};
&sdhci0 {
	u-boot,dm-pre-reloc;
};
&uart1 {
	u-boot,dm-pre-reloc;
};
 
&qspi {
	u-boot,dm-pre-reloc;
};
&flash0 {
	compatible = "micron,m25p80", "s25fl128s", "spi-flash";
};

    Petalinux commands 

    petalinux-create --type project --template zynq --name zynq_hello
petalinux-config --get-hw-description ../zynq_hw 
petalinux-config -c kernel
petalinux-build
petalinux-boot --jtag --prebuilt 3

    Petalinux project ZYBO 7Z-20 using "system-user.dtsi" from v2017.4

    in Embedded Linux

    Posted · Edited by joniengr081

    Hi, I have got the "system-user.dtsi" from the following source petalinux 2017.4 and manually updated that file in my project which I have created in petalinux 2021.1 but I am not able to run the config and build commands. 

    https://github.com/Digilent/Petalinux-Zybo-Z7-20

    Summarized steps:

    1- Create new hardware project in Vivado 2021.1

    2- Add the board ZYBO Z7-20

    3- Add ZYNQ PS in block design

    4- HDL wrapper, Synthesis, Implementation

    5- Generated bit stream and export the hardware design

    6- Launch Vitis 2021.1

    7- Created ZYNQ platform

    8- Have tested Hello Word project in serial terminal

    9- Created a new petalinux project using the following template command in petalinux 2021.1.

    10- petalinux-create --type project --template zynq --name zynq_hello_project

    11- Manually updated "system-user.dtsi" from https://github.com/Digilent/Petalinux-Zybo-Z7-20

    12- petalinux-config --get-hw-description <PATH-TO-XSA Directory>/<PATH-TOXSA>

    13- petalinux-config -c kernel

    14- exit with default settings

    15- The compilation stuck with the following errors
