Hi everyone,
today I received a RK3188-SOM-EVB. (
https://www.olimex.com/Products/SOM/RK3188/RK3188-SOM-EVB/)
Now I am trying to get it working, however, the Wiki (
https://www.olimex.com/wiki/RK3188-SOM) seems to be somewhat out of date - the torrent links for the prebuilt Debian images apparently have no peers from where I could download the ima (both, the v1 and the v2), the Link for the prebuilt Ubuntu image is also no longer pointing to an image (and the image mentioned is for 14.10, not the freshest Ubuntu...) - whe whole folder structure is not as written in the wiki, so I am a little bit confused on where to get prebuilt images.
Then I tried to compile my own image - but again, the wiki is not "compatible" with my current Ubuntu 18.04:
- instead of gcc-4.7-arm-linux-gnueabihf, I had to install gcc-8-arm-linux-gnueabihf
- instead of uboot-mkimage, I had to use u-boot-tools
So far, so good (or that´s what I thought).
Then I created the .config file for make with
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- olimex_rk3188_defconfig, apparently successful.
According to the wiki, I now should be able to build the kernel by running
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j4 kernel.img - which fails.
The make command could not find a command called
arm-linux-gnueabihf-gcc.
Google pointed me to
https://packages.ubuntu.com/de/xenial/gcc-arm-linux-gnueabihf, so I did
sudo apt install gcc-arm-linux-gnueabihf.
Yay, one step further! Now the make error looks different:
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j4 kernel.img

For now, I am using this post to document stuff I am doing/trying but if anyone has any enlightening ideas on what am I doing wrong or what I could do to get a Linux (Debian or Ubuntu, I don´t care) running on my RK3188 faster (or a working link to an image), I would be grateful!
TIA,
