I'm using Linaro Release 15.12 LSK (without OP-TEE) + OpenEmbedded Minimal Filesystem on Juno-r1 Board.
I'm trying to put the Juno board into the Sleep-state referring to ARM Versatile Express Juno r1 Development Platform Technical Reference Manual.
But it seems to reboot and fall into the error state, even if I push the Soft Reset button briefly.
Does anyone know how to put the Juno board into the Sleep-state ?
Thank you for your help.

Hi taken,
Thanks for taking time to explain the details.
I understand you are using Linaro 16.05 release now, but I want to make know which
kernel are you trying ? Is it Linaro release or the mainline.
One possible reason could be the some driver is taking long to complete it's suspend
and rtc expires before entering suspend.
I tried with defconfig on v4.7-rc4 and I don't see any issue.
I need more information on the kernel configuration to check this.

Sudeep
Hi Sudeep,
Thanks for your prompt reply.
I tried with defconfig on Linaro 16.05 latest and the issue did not happen as well as v4.7-rc4.
There is much difference between defconfig and linaro config, so I am trying to check them.
Regards
Hi,
I reported that the issue surfaces when I try to suspend & resume twice continuously with Linaro 16.05 latest above.At that time I used prebuilt binaries (snapshots.linaro.org/.../ : Now not found),but the binaries that built from a source code (fetched by the following commands) does not surface the issue.
# repo init -u https://git.linaro.org/landing-teams/working/arm/manifest -b 16.05 -m pinned-latest.xml # repo sync
Thank you.
