Update documentation to include the Cyclone V SoC Preloader development flow. This include the update of Preloader handoff through qts-filter.sh script. At same time, removed the SDMMC documentation as its using DM now.
Good stuff . s/folder/directory/ , this is not windows.
haha sound like a habit using windows term :)

+1. Please refer to SOCEDS documentation on generating handoff for Preloader
- Upon successful generation, there will be a folder
"software/preloader" at
^^^^^^
- the directory of your Qsys project.
+2. Then, you need to invoke qts-filter.sh at arch/arm/mach-socfpga folder to
- process the generated handoff files into Preloader source code.
- $ sh arch/arm/mach-socfpga/qts-filter.sh <device> <your Qsys
directory> \
<your Qsys directory>/software/preloader> <destination ofhandoff files>
- Example:
- $ cd <u-boot directory>
- $ sh arch/arm/mach-socfpga/qts-filter.sh cyclone5 \
/hardware/cv_soc_devkit_ghrd/ \/hardware/cv_soc_devkit_ghrd/software/preloader/ \board/altera/cyclone5-socdk/qts/You should be explicit that these are two separate examples , one for CV and the other one for AV .
Sure, always to good to explain in detailed
- $ cd <u-boot directory>
- $ sh arch/arm/mach-socfpga/qts-filter.sh arria5 \
/hardware/av_soc_devkit_ghrd/ \/hardware/av_soc_devkit_ghrd/software/preloader/board/altera/arria5-socdk/qts/+3. Build the Preloader + U-Boot
It's called U-Boot SPL , not preloader .
Will fix
- $ export CROSS_COMPILE=arm-altera-eabi-
- $ make mrproper
- $ make socfpga_cyclone5_defconfig
- $ make
It's worth mentioning the generated u-boot-with-spl.sfp and how to install it onto a card (mention partitioning layout) and into QSPI NOR (just write the binary at the beginning). Regarding QSPI NOR, it might be worth mentioning quartus_hps, see : https://rocketboards.org/foswiki/view/Documentation/GSRD131QspiProgra m
Sure, I will add more as I just received email to explain these steps :)
Thanks Chin Liang
