Hi there,

I started to develop Linaro Android 13.07 on Arndale Board.

It's working fine with HDMI display and mouse input, but I have some issues on it.

1. I cannot change date & time.

I tried "Settings -> Date&Time" and "time -s 20130823.130000" command
via serial console. But it does not change time on the device. As a result,

my application that uses SSL fails to connect to a server since time is set to
1970, which makes certificate validation fail.

Does anyone know how to change date & time?

I guess it's because there is no the alarm kernel support.

Maybe you can try to add the change here:

 although it's only for the Origen dual board.

Thanks,

Yongqin Liu

2. I cannot change Linux boot parameter.

I want to boot Linux kernel on a single processor hardware, so I'd like to
make it No SMP. We can do it by setting "nosmp" argument for kernel
boot. I tried changing u-boot parameters mmcargs so that it includes
nosmp, but booting kernel seems not to have one. I confirmed it by
looking at /proc/cmdline.

What parameter on u-boot do I have to change?

Thanks,

Yoshi
