Any Cyclone V soc bare metal startup project settings available?

The main issue is from is order:

From the : intel-socfpga-hwlib\examples\CVAV\Altera-SoCFPGA-HardwareLib-Timer-CV-GNU\Makefile.inc

What's the default settings of the MAKE?

Hi CAlex,

I will try to check if got any guide provided.

Anyway when I run baremetal application, I only consider the Makefile to add in those required files to support my application code other than the main.c.

Example like below:

EXAMPLE_SRC := main.c leds_cv.c pl330_tst.c alt_dma.c alt_dma_program.c alt_bridge_manager.c alt_fpga_manager.c alt_address_space.c

Thanks.

Hi CAlex,

I wasn't able to get any specific guide regarding the makefile.inc which you requested.

Are you not able to download the content from the link which you have provided? The link was able to work on my side.

May I know what is your issue when working with baremetal?

Thanks.

Hi CAlex,

Did you perform git clone from https://github.com/altera-opensource/intel-socfpga-hwlib to install linaro?

git clone https://github.com/altera-opensource/intel-socfpga-hwlib

cd intel-socfpga-hwlib/tools

./install_linaro.sh

Thanks.

Hi,

while I'm trying getting started preloader.ds launcher, there was an error:

The reset capability system is not available

Any idea to solve that?

Hi CAlex,

Are you mentioned the part where you are trying to build the u-boot?

After you have obtained and built your ghrd, you will proceed to the next step to consider consider u-boot

Referring to this document on the part where you are going to build u-boot:

https://www.rocketboards.org/foswiki/Documentation/SoCEDS

Note that you will need the embedded_command_shell.sh to perform the build.

Thanks.

Hi CAlex,

If you wanto run from ddr you will need the SPL(u-boot-splx4.sfp) to init the ddr first.

To boot from ddr you will need to run the below cmd when makding your application code:

Refer to the section(Software Examples) with the table https://github.com/altera-opensource/intel-socfpga-hwlib

if ddr the cmd will be:

make SEMIHOSTED=0 MEMORY=ddr

Thanks.

Also I got several issues dealing with example makefile:

1. CP: option -n can't be used so I delete it

2. NEWLIB_ROOT is wrong , in my root system(X86_64 windows with MSYS 1.0) the root was:..\intel-socfpga-hwlib\tools\newlib\usr\arm-eabi

instead of ..\intel-socfpga-hwlib\tools\newlib\usr\local\arm-eabi

I dont know weather it's my failure to compeletely download it or it is because of the version/tool change.

3. The make file always point at ARM Compiler 5 (which did not exist in ARM DS), you may need to update the Makefile with armcc 6

And point three is my another new question (God bless us all) : how can I let the Makefile point to ARMCC 6?

The followed is the Makefile order:

/*--------------------------------------------------START FROM HERE-----------------------------------------------------------------*/

CROSS_COMPILE := arm-eabi-
CC := armcc
AS := armasm
LD := armlink
NM := $(CROSS_COMPILE)nm
OD := $(CROSS_COMPILE)objdump
OC := $(CROSS_COMPILE)objcopy

LINKER_SCRIPT := $(HWLIBS_SRC_ROOT)/src/linkerscripts/cvav-$(MEMORY).scat
MULTILIBFLAGS := --diag_error=warning --diag_suppress=9931 --cpu=Cortex-A9 --no_unaligned_access
CFLAGS := -g -O0 --c99 --strict $(MULTILIBFLAGS) $(INCLUDE_DIRS) -D$(ALT_DEVICE_FAMILY) -DALT_FPGA_ENABLE_DMA_SUPPORT=1 -D_USE_STDLIB -DALT_BRIDGE_PROVISION_F2S_SUPPORT -D$(ALT_DEVICE) $(UART_DEFINES) $(ADD_CFLAGS_ARMCC)
ASMFLAGS := -g $(MULTILIBFLAGS)
LDFLAGS := --strict $(MULTILIBFLAGS) --entry=alt_interrupt_vector --scatter=$(LINKER_SCRIPT)
ifeq ($(SEMIHOSTED), 1)
LDFLAGS += --keep=__auto_semihosting
endif
ODFLAGS := -d
OCFLAGS := --bin --output=

/*-------------------------------------------------------END------------------------------------------------------------------------------------*/

The following is the error when trying to compile the first file:

process_begin: CreateProcess(NULL, armcc -g -O0 --c99 --strict --diag_error=warning --diag_suppress=9931 --cpu=Cortex-A9 --no_unaligned_access -Ilib -Ihwlib/include -Ihwlib/include/soc_cv_av -Ihwlib/include/soc_cv_av/socal -ID:\board\cyclone_V_soc\intel-socfpga-hwlib\tools\newlib\usr\arm-eabi/include -Dsoc_cv_av -DALT_FPGA_ENABLE_DMA_SUPPORT=1 -D_USE_STDLIB -DALT_BRIDGE_PROVISION_F2S_SUPPORT -DCYCLONEV -DPRINTF_HOST -c hwlib/src/hwmgr/alt_address_space.c -o objs_ARMCC_CYCLONEV/alt_address_space.o, ...) failed.

Hi CAlex,

I build everything in linux environment without using Arm DS

I was using the building bootloader to build and get the spl from https://www.rocketboards.org/foswiki/Documentation/BuildingBootloaderCycloneVAndArria10#Cyclone_V_SoC_45_Boot_from_QSPI

"cv_soc_devkit_ghrd/software/bootloader/u-boot-socfpga/spl/u-boot-splx4.sfp \"

After install the toolchain, I will export the path as below to further build the application.

########################################

# get hwlibs, install toolchain

########################################

git clone https://github.com/altera-opensource/intel-socfpga-hwlib

cd intel-socfpga-hwlib/tools

./install_linaro.sh

export PATH=`pwd`/gcc/bin:$PATH

Thanks.
