Hi,
In UltraZed-3EG-IO-Card.
1. I cannot read from memory of PL side, when I am in sdcard mode. in sdk mode I don't have problem reading those addresses.
2. I cannot also set the USB3
Although I done huge effort that all tools and files will have the same version 2018.2 ( I installed new Petlinux 2018.2, create new project with bsp of 2018.2, created a new project from scratsch in Vivado 2018.2, also installed Vivado 2018.2)
I cannot read from PL memory, I tried all options:
devmem 0x80000000 16
devmem 0x80000000 32
I got the following response:
root@uz3eg-2016-2:~# devmem 0x80000000 16

When I read the DDR memory I don't have problem
devmem 0x5000
I tried to set the memory to be dedicated to 0xa0000000
In the dtsi file I have added the memory dedicated part also, but I got the same response
/include/ "system-conf.dtsi"
/include/ "openamp.dtsi"
/{
reserved-memory {
#address-cells = <2>;
#size-cells = <2>;
ranges;
reserved: dma_buffer@0 {
reg = <0x0 0x0 0x0 0x00A00000>;
};
};
reserved-driver@0 {
compatible = "xlnx,reserved-memory";
memory-region = <&reserved>;
};
chosen {
bootargs = "earlycon console=ttyPS0,115200 clk_ignore_unused root=/dev/mmcblk0p2 rw rootwait isolcpus=3";
};
----------------------
I also cannot set the USB3,
I tried with the following commands to set the USB3:
ifconfig usb0 192.168.100.1 netmask 255.255.255.0 and modprobe g_ether
But they were not recognized
[ 1661.448807] Configuring USB3:

Thanks in advance,
