Linux host running Ubuntu 20.04 is not able to detect the storage device

[Sandra_23]

Setup:

LS1043ARDB board, booted from SD card using LSDK 21.08, RT kernel

USB-2 was made device port by changing dtsi file:

arch/arm/boot/dts/freescale/fsl-ls1043a.dtsi

After booting the kernel, the following is done:

root@localhost:~# pwd

/root

root@localhost:~# mkdir gadget_test

root@localhost:~# cd gadget_test/

root@localhost:~/gadget_test# dd if=/dev/zero of=./test bs=1M count=500

Have you updated dts as the following?

Device Tree update, change property dr_mode’s data from “host” to “peripheral”, add property maximum-speed = “super-speed”;
as below:
usb0: usb3@2f00000 {
compatible = "snps,dwc3";
reg = <0x0 0x2f00000 0x0 0x10000>;
interrupts = <0 60 0x4>;
dr_mode = "peripheral";
snps,quirk-frame-length-adjustment = <0x20>;
snps,dis_rxdet_inp3_quirk;
maximum-speed = “super-speed”;
};
