Hi Jan,

This patch adds support for the iwg20m board on ISAR CIP Core.

[PATCH] iwg20m: add support for this board

For now, it uses the u-boot shipped with the board.
We could improve that in the future, but for the first release
I think it is not critical.

Thanks,
Daniel

[cip-dev] [PATCH] iwg20m: add support for this board

[Daniel Sangorrin]

This patch adds support for the iwg20m board to isar-cip-core.

- Kernel version notes

This board is only supported by the 4.4 kernel.
The document doc/README_iwg20m.md already explains that.

- U-boot notes

The u-boot version shipped with the board is rather
old (2013.01) and comes without distro boot support.
We could try building it with CONFIG_CMD_SOURCE to use
a boot.scr script. However, the build gave several
errors probably caused by incompatibilities with
modern compilers. Additionally, u-boot resides
on an SPI device and any failures while updating
it will brick the board. For all these reasons,
this patch relies on the u-boot shipped with the
board completely. The user needs to setup some
additional u-boot environment variables as described
in doc/README_iwg20m.md

- Kernel configuration notes

The configuration is based on the kernel's
shmobile_defconfig. Then it adds some
configuration bits for booting on an SDCard with
EXT4, booting from a ramdisk, and running Systemd.

- Bmap notes

The document doc/README_iwg20m.md uses bmaptool to
flash the image onto an SDCard. This functionality
is not yet available on the ISAR version used by
isar-cip-core. For now, you can either backport the
bmap patch [1] or use dd as explained in the README.

+# ISAR CIP Core: Instructions for the Renesas IWG20M board
+
+Version: 20190606
+Copyright: Toshiba corp.
+
+## Build the CIP Core image
+
+Use [kas-docker](https://github.com/siemens/kas/blob/master/kas-docker) to build the image. Currently this board is only supported by the CIP kernel version `4.4.y`. For that reason, add `:opt-4.4.yml` to the build command line.
+
+```
+$ git clone https://gitlab.com/cip-project/cip-core/isar-cip-core.git
+$ cd isar-cip-core
+$ wget https://raw.githubusercontent.com/siemens/kas/master/kas-docker
+$ chmod a+x kas-docker
+$ ./kas-docker --isar build kas.yml:board-iwg20m.yml:opt-4.4.yml
+```
+
+After the build is finished, insert a micro SDCard and flash the image with `bmaptool` (a better `dd`). Make sure you substitute `/dev/sdX` by the device file corresponding to your SDCard.
+
+```
+$ sudo apt install bmap-tools
+$ sudo bmaptool copy --bmap build/tmp/deploy/images/iwg20m/cip-core-image-cip-core-iwg20m.wic.img.bmap build/tmp/deploy/images/iwg20m/cip-core-image-cip-core-iwg20m.wic.img /dev/sdX
+```
+
+[Note] the bmap file will only be created on newer versions of ISAR. If the bmap file was not created then use `dd`.
+
+## U-boot settings
+
+
+In order to boot from the micro SDCard, we need to set some environment variables on u-boot. Insert the card on the microSD slot (on the upper hardware module), and a USB-serial cable to the USB Debug port (on the lower hardware module). Open a serial terminal (here we use `picocom`), and then switch on the board and enter the u-boot interactive command line to set the environment variables.
+
+```
+$ picocom -b 115200 /dev/ttyUSB0
+iWave-G20M > setenv bootargs_msd 'setenv bootargs ${bootargs_base} root=/dev/mmcblk0p2 rw rootfstype=ext4 rootwait'
+iWave-G20M > setenv bootcmd_msd 'run bootargs_msd;run fdt_check;mmc dev 1;fatload mmc 1 ${loadaddr} zImage;fatload mmc 1 ${fdt_addr} r8a7743-iwg20d-q7-dbcm-ca.dtb;bootz ${loadaddr} - ${fdt_addr}'
+iWave-G20M > saveenv
+```
+
+Note that `mmcblk0p2` represents the SDCard when running the CIP kernel 4.4. Once the environment variables are setup, you can boot from the SDCard as follows
+
+```
+iWave-G20M > run bootcmd_msd
+```
+
+Finally, to make that persistent set the `bootcmd` variable.
+
+```
+iWave-G20M > setenv bootcmd 'run bootcmd_msd'
+```

As you are cross-posting, the subject should probably also contain some tag like 
"[isar-cip-core]", to clarify the target project. In fact, that would even help 
on cip-dev as we now have quite a few projects there which take patches.

If the machine currently only works with cip-4.4, you should also set the 
preferred kernel version here.

Insert the card on the microSD slot (on the upper hardware module), and a USB-serial cable to the USB Debug port (on the lower hardware module). Open a serial terminal (here we use `picocom`), and then switch on the board and enter the u-boot interactive command line to set the environment variables.

Does the pre-installed u-boot support ext4? If yes, why not using u-boot-script 
and loading /boot/boot.scr instead? That would avoid duplicating information 
like partitioning and kernel parameters here.

[cip-dev] [PATCH] iwg20m: add support for this board

ext4load seems to be available on the u-boot command line.

After loading boot.scr, don't we need the "source" command to work? "source" does not seem to be configured in the pre-installed u-boot.

Also, to create boot.scr we need mkimage. I wonder if modern Debian u-boot-tools' mkimage will create a boot.scr that is compatible with the pre-installed u-boot (remember that I couldn't build the old u-boot with the new compilers).

I guess, I can just load the image with ext4load instead of fatload. Not sure why the original instructions required two partitions then..

Thanks,
Daniel

You could just use the mkimage that comes from your u-boot source to be
certain. I do something similar [1] since the upstream debian
u-boot-tools do not support creating signed fit images.

Hello Ben,

Sorry, I realized that there were a few issues in the Quickstart
so I am resending the patch. Please ignore the previous one.
