Arrow SoCKit Linaro Desktop with ACDS 14.0 and Linux 3.13

Hi, I thought I'd provide some tips on using Arrow SoCKit Linaro Linux Desktop on ACDS 14.0, as I got it working just recently. This assumes you already have this one installed successfully:

http://www.rocketboards.org/foswiki/view/projects/sockitlinarolinuxdesktop

* Used Makefile provided in <ACDS 14.0>/embedded/examples/hardware/cv_soc_devkit_ghrd

* The preloader and uboot image built seem to work fine this time.

make preloader uboot;

cd software/preloader;

cat preloader-mkpimage.bin u-boot.img > boot-partition.img

dd if=boot-partition.img bs=512 of=<boot partition of microsdcard>

* Use script git_clone.sh in embedded/embeddedsw/socfpga/source to get socfpga-3.13 kernel.

make socfpga_defconfig

make -j4 uImage

* Tedious: the default uImage is now too big for the default 10Mb partition on the microsd card. Went through menuconfig and turned off a lot of stuff. Also turned on CONFIG_FB and CONFIG_FB_ALTERA_VIP. My kernel .config file is attached as config-3.13.txt. This should just squeeze onto the boot partition with the uncompressed soc_system.rbf file.

* USB didn't work initially: that's because the default example cv_soc_devkit_ghrd soc_system.dts doesn't match the kernel dts. I copied hps_0_usb0 and hps_0_usb1 from arch/arm/boot/dts/socfpga.dtsi to my soc_system.dts (built from sopc2dts). Don't forget usbphy0. I then had to compile the dts to dtb using Altera's 13.1 embedded/hotools/gnu/H-i686-pc-linux-gnu/bin/dtc which is no longer provided in 14.0.

Working HPS USB 3.13 DTS looks like this:

usbphy0: usbphy@0 {

# phy-cells = <0>;

compatible = "usb-nop-xceiv";

status = "okay";

};

hps_0_usb1: usb@0xffb40000 {

compatible = "snps,dwc2";

reg = < 0xFFB40000 0x0000FFFF >;

interrupt-parent = < &hps_0_arm_gic_0 >;

interrupts = < 0 128 4 >;

clocks = < &usb_mp_clk >;

clock-names = "otg";

phys = <&usbphy0>;

phy-names = "usb2-phy";

enable-dynamic-fifo = <1>;

host-rx-fifo-size = <0xa00>;

host-perio-tx-fifo-size = <0xa00>;

host-nperio-tx-fifo-size = <0xa00>;

dma-desc-enable = <0>;

status = "okay";

}; //end usb@0xffb40000 (hps_0_usb1)

* The qsys file auto-upgraded to 14.0 without problems.

That got me booted up and running Linaro.
