[cip-dev] B@D: iwg20m support

[trung.huynh.uw@rvc.renesas.com (Trung. Huynh)]

Dear Daniel,

One important thing is how big is root fs size get maximal? Is it limited?
Your configuration on iwg20m is to assign 8 ramdisks with enlargement of each block 100MB approx:

CONFIG_BLK_DEV_RAM=y
CONFIG_BLK_DEV_RAM_COUNT=8
CONFIG_BLK_DEV_RAM_SIZE=102400
CONFIG_EXT4_FS=y
CONFIG_EXT4_USE_FOR_EXT2=y
CONFIG_USB_XHCI_RCAR=n

If we try to test more function as our wish (more dependencies in ramdisk), assuming that the root fs size could be 150MB.
For G1M 1GB of RAM, just increase CONFIG_BLK_DEV_RAM_SIZE to 250000 and reduce CONFIG_BLK_DEV_RAM_COUNT to 4 iWave.

-> Output is booting failed, attachment to show what occurring.

Regards,
Trung

The CIP Core rootfs was built using Deby (poky build system + meta-debian). You can see a tutorial in the CIP wiki and a more up-to-date README and kas file in the source code.

https://wiki.linuxfoundation.org/civilinfrastructureplatform/cip-core-quickstart
https://gitlab.com/cip-project/cip-core/blob/master/deby/poky/meta-cip-iwg20m/README.IWG20M.txt
https://gitlab.com/cip-project/cip-core/blob/master/deby/poky/meta-cip-iwg20m/kas-iwg20m.yml

An overview of the CIP Core is here:
https://wiki.linuxfoundation.org/civilinfrastructureplatform/cip-core
https://gitlab.com/cip-project/cip-core/blob/master/deby/README.md

For the BBB please check this other Readme and kas file:
https://gitlab.com/cip-project/cip-core/blob/master/deby/poky/meta-cip-bbb/README.BBB.txt
https://gitlab.com/cip-project/cip-core/blob/master/deby/poky/meta-cip-bbb/kas-bbb.yml

You can add the packages "openssh nfs-utils rt-tests strace procps", they are available in meta-debian.

Unfortunately, you cannot simply add "meta-qt5" because it may conflict with meta-debian. Instead you would need to use meta-debian qt5 recipes (only if you really need qt5 for testing RT).

Thanks,
Daniel Sangorrin
