Subject: [cip-dev] Renesas dev CIP repository announcement

Dear CIP friends,

I’d like to announce the availability of a development repo [1] based
on the CIP Kernel for the iWave RZ/G1M Qseven Development Platform

The main aim of this repository is to allow CIP users to get up and
running with the Renesas CIP reference platform. Please note that this is
just an interim step as support for the platform is added
upstream/backported to the CIP Kernel.

Currently there are two branches, one based on v4.4.55-cip3, and the other
based on v4.4.69-cip4.

Please use the “shmobile_defconfig” configuration when compiling, and
use r8a7743-iwg20m.dtb. uImage LOADADDR should be set to
"0x40008000". For u-boot environment settings, please see the iWave
documentation that should come with the boards.


I just wanted to tell you that I managed to build and boot the CIP kernel on
the iwg20m board from tftpboot.

The only problem I had was that the original u-boot environment (kernel
3.10) used /dev/mmcblk2p2, whereas for kernel CIP 4.4 (using the same
original filesystem) I had to change that to root=/dev/mmcblk0p2.
Thank you for pointing this out. I'm afraid that everyone will need to make this change if using the supplied u-boot env. Sorry I missed this.

Apart from that:
- the upper blue usb 3 connector doesn't seem to work. (it didn't work
either on the factory kernel 3.10)
The RZ/G1M only supports one channel of USB3.0. The carrier board is used for other SoC SOM modules, hence there are some connectors that will not work either due to lack of support or multiplexing - SATA, HDMI, the upper USB3.0 port.

For full details, please see the "QsevenDevKit-HardwareUserGuide" which should have come with the platform on a CD.

You can also see the block diagram on the iWave website [3].

- reboot doesn't seem to work (it works on the factory kernel 3.10).
This is a known issue that we currently have a workaround for. For development we could add this to [4], but it's a bit ugly.

By the way, do you have some test script to check that every module is
working fine?
Not at the moment, we are currently working on adding support for the CIP test framework, but this won't be ready for a while yet I'm afraid.


Kind regards, Chris
