Re: Query regarding booting XEN on Banana Pi-M1 board.

[siddhartha v <siddhuvgowda.18695@xxxxxxxxx>]

Hi Bertrand sir,

  As i am not able to give target machine=bananapim1 i tbought of giving cubeiboard2 as it also uses the allwinner a20 soc. 

But every time I do bitbake @82% the gcc-sanitizers-8.3.0-r0 do_compile task starts but at that time whole system hangs and i dont have any option other than doing direct power off of the system. I waited at this stage for about 4-5 hrs 3 times.

May i know what is wrong here please.

This happened when i tried to build for RPI3 also.

Hi Siddhartha,

There are several errors here and the main one is there is not support for your board in Yocto.

Meta-arm-autonomy provides a way to use xen but does not provide the bsp for your board.

To use it you will first need to have a BSP for your board in Yocto.

You might need to search for a layer supporting your board and once found add it to your project.

Regards

Bertrand

Hello @Bertrand Marquis sir, 

I referref the docs and trying to build the Xen for Banana-Pi M1. 

my BBfile.conf is:

and changes local.conf

MACHINE ??= "bpi-m1 " (Here I have tried multiple names for banana Pim1)

But the bitbake is not happening below I am attaching the errors may I know what wrong I am doing here please:

It seems that their certificate expired. This should be solved shortly (I hope).

An other solution is to directly do a git clone of the layer git://git.yoctoproject.org/meta-arm
