UEFI: stub-kernel TFTP boot test fail on v7 and v8

[Fu Wei]

(1)can not setup tftp boot info properly
When setup tftp boot info, I can not input FDT path in one time,
I need to :
 a, input FDT path(go back to MENU, the path is wrong)
 b, clean FDT path
 c, add FDT path again
after this three steps, The FDT path of tftp boot will be right in the boot MENU.
Please check the file attached in detail.

(2) after making right setting, kernel can not be brought up successfully,
 a: sometimes it will show a lot of "Synchronous Exception"

BTW, There are not these problem in ARMv7 test, I can run TFTP boot on v7 FAST Model.

[Leif Lindholm (leif-lindholm)]

Confirmed. Something went wrong in the January release. Will be resolved in 2014.02.

[Roy Franz (roy-franz)]

Networking does not work for me on v7 models - I get the error:

Unable to set the NIC configure parameters, Access Denied

when I try to configure the ethernet device either statically or using dhcp.

I see the same behavior on the FVP fast model and QEMU.

[Anmar Oueja (anmar)]

Fu Wei was going to test the 2014.03 linaro-edk2 tree and see if he can still reproduce this issue.

[Fu Wei (fu-wei)]

problems still exist in linaro-edk2(http://snapshots.linaro.org/components/kernel/linaro-edk2/12)

[Leif Lindholm (leif-lindholm)]

Olivier just pushed some fixes for exception handling. Revisit with first build of 2014.05.

Hi Fu Wei,

There is no new -rc yet.
Please wait until I let you know we actually have something worth testing.

Hi Leif,
Thanks for your info!
now , for UEFI, we have three bugs I can test:
1.Ping command causes exception on FVP aarch64 model (waiting for fix)
https://bugs.launchpad.net/linaro-uefi/+bug/1279574
2.when exit from grub - uefi shell, then reenter uefi shell , got "Synchronous Exception:" (waiting for fix)
https://bugs.launchpad.net/linaro-uefi/+bug/1311745
3.UEFI: stub-kernel TFTP boot test fail on v7 and v8 (waiting for fix)
https://bugs.launchpad.net/linaro-uefi/+bug/1274126

So once we have anything can test, just let me know :-)

 bug is still present, in http://snapshots.linaro.org/components/kernel/linaro-edk2/18/release
we still can not boot Linux kernel by uefi tftpboot. I got "ERROR: Did not find Device Tree blob.".

although, we can boot kernel without dtb, but it seems uefi tftpboot still want a dtb for booting a linux kernel.

[Ryan Harkin (ryanharkin)]

Have you tried creating a new tftp boot option? You're updating an
existing one that perhaps already has a DTB configured, so a new entry
might get different options. So the bug could be in "Update...", not "Add
Boot Device Entry".

[Leif Lindholm (leif-lindholm)]

Ok - let's postpone validation for another month then.

We will be throwing out the built in Linux loader and boot properly
using the stub instead.
(Yes, this means we also need to add the .dtb to the UEFI image - an
excellent exercise for the sprint.)

Another problem is :
File path of the EFI Application or the kernel: efi/LEG/Image

(wait a very long time, it seems uefi is downloading the Image)

Is your application is an OS loader? [y/n] n
......

then once you boot the kernel by tftp, you still need to wait for downloading again.

I have retested the uefi(in http://snapshots.linaro.org/components/kernel/linaro-edk2/18) several times, the result is below:

THis bug has been fixed.

The problem I met yesterday is in "uefi-vars.fd" file.

----------------------------
UEFI function test result:
PXE boot GRUB PASS
PXE boot Linux PASS
TFTP boot GRUB PASS
TFTP boot Linux PASS
----------------------------
