Hello,
I have connected USB hard disk to P1020RB
Which board is this? Neither "git grep -i P1020RB" nor "find . iname '*P1020RB*'" yield any result.
and in command prompt(u-boot) i used command => usb start (Re)start USB... USB: Register 10011 NbrPorts 1 USB EHCI 1.00 scanning bus for devices... 3 USB Device(s) found scanning bus for storage devices... 1 Storage Device(s) found
=> usb dev
USB device 0: Vendor: Seagate Rev: 0130 Prod: Portable Type: Hard Disk Capacity: 476940.0 MB = 465.7 GB (976773168 x 512)
and USB got detected.
but If i used the same command in our custom board => usb start (Re)start USB... USB: Register 10011 NbrPorts 1 USB EHCI 1.00 scanning bus for devices... 1 USB Device(s) found scanning bus for storage devices... 0 Storage Device(s) found
=> usb dev
USB device -1: device type unknown
How do resolve this issue and why the device is not detecting my USB hard disk.?
Considering that you're trying this on a custom board, and assuming "P1020RB" is a nickname for a board supported in mainline U-Boot, there are two possibilities:
1) the custom board uses exactly the same U-Boot (source, configuration and binaries) as P1020RB, and the issue is in HW, in which case we can barely help;
2) the custom board uses a custom U-Boot, and we can barely help too, as this issue is not about (recent) mainline U-Boot code.
