ls2088A hang after 'reboot'

[jiafang]

Use LSDK 17-12 version kernel to bootup ls2088ardb reference board.

Login after about 3mins~5mins, and then 'reboot', the board can not boot up again.

Part log is:

[...

e1000e: EEE TX LPI TIMER: 00000000
reboot: Restarting system
Re

]

The board stops at here.

If login after 15mins or 20mins, the board can boot up well.

Is there anyone has the same issue ?

Hi Yiping Wang

It seems like I have deleted your reply after I edited to add the attached file(bootlog) ,sorry, I didn't mean it.

It is easy to reproduce, you can try it as well.

I'm not sure it is related to NFS bootway.

Thanks,

Fang

Hello jia fang,

The issue QUBOOT-3723 has already been fixed in the patch [U-Boot] driver: fsl-mc: Perform fsl-mc fdt fixup for lazyapply dpl - Patchwork .

It seems that the reboot problem is related with E1000 Timer, are you using NFS rootfs now?

Would you please provide the whole console log including u-boot, Linux Kernel booting up and the execution of reboot command?

Have a great day,
TIC

It is easy to reproduce with the NFS boot way. You can have a try.

But I'm not sure if without NFS boot, it can be reproduced as well.

Please see the attachment.

Oh, I use the flash vbank4  and the lsdk1712 version and find that the issue is still there.

I tried to update the firmware to LSDK1712 version. then I found the mc bus does not probed.

There should be some problem in MC10.4.0.

The issue is same as the LSDK1712 open issue QUBOOT-3723. So I change to use the 'fsl_mc apply dpl' not the 'lazyapply', the MC works well now.

And it seems like the 'reboot' issue disappear now.

There is some commits related 'firmware: psci", is it possible there is some issue in PSCI ?
