LS1043ARDB LSDK 20.04 usb device enumeration errors

grahamp — Fri, 05 Aug 2022 14:53:14 GMT

Hello,

I am having trouble with usb device enumeration on a recently purchased LS1043ARDB.

My mass storage usb device is detected by the LSDK installed on the LS1043ARDB as shipped booting from nor:

QorIQ LSDK (NXP Reference Distro) 2.0 TinyDistro /dev/ttyS0

However, if I build LSDK 20.04 using yocto and then tftp the files to the device I am getting usb errors:

[ 66.286514] xhci-hcd xhci-hcd.0.auto: Error while assigning device slot ID
[ 66.286543] xhci-hcd xhci-hcd.0.auto: Max number of devices this xHCI host supports is 127.
[ 66.286564] usb usb1-port1: couldn't allocate usb_device

I have found this https://community.nxp.com/t5/Layerscape/USB-not-detected-LS1043ARDB/m-p/1396725 which looks very similar. I tried the solution proposed in that post but I am still get usb errors.

My procedure for loading the files once extracted from https://www.nxp.com/lgfiles/sdk/lsdk2108/boot_LS_arm64_lts_5.10.tgz is:

setenv bootargs "console=ttyS0,115200 root=/dev/mmcblk0p1 rw rootwait earlycon=uart8250,mmio,0x21c0500"
setenv ipaddr 192.168.0.10
setenv serverip 192.168.0.30
tftp 0xa0000000 Image
tftp 0xb0000000 fsl-ls1043a-rdb-sdk.dtb
booti 0xa0000000 - 0xb0000000

The boot log is attached.

I see the same errors as on my LSDK 20.04 yocto build.

Can you please advise?

enabled debug in xhci driver and see a usb timeout message:

I also verified I can access mass storage device from u-boot:

So now hardware issue but certainly looks like a linux kernel problem.

Any takers?
