Arria 10 SoC Dev Kit Baremetal HPS examples issue & workflow

Hi, I recently acquired an Arria 10 SoC dev kit but I'm really struggling to run either the examples on embedded-software/bare-metal or the ones included in SoC EDS pro 20.1, trying to follow the ins...

Hello,

Thank you for your reply, I followed your steps but not sure if it was the right way because it is still not working.

  1. Generated the .bin and copied inside sd card
  2. Stopped uboot and launched the application in uboot by:
Hit any key to stop autoboot:  0
=> fatload mmc 0:1 0x00100040 application_example_v1_1.bin
67752 bytes read in 6 ms (10.8 MiB/s)
=> go 0x00100040
## Starting application at 0x00100040 ...

U-Boot SPL 2021.04 (Sep 02 2021 - 08:43:37 +0000)

As you can see uboot restarts again without printing anything, this i the makefile configuration in the Altera-SoCFPGA-HardwareLib-16550-CV-GNU example (modified the lines to aim to arria10 instead of cyclone V) :

COMPILER ?= GNU
#COMPILER ?= ARMCC

#MEMORY ?= ddr
MEMORY ?= ocr

#SEMIHOSTED ?= 1
SEMIHOSTED ?= 0

ADD_CFLAGS_GNU :=
ADD_CFLAGS_ARMCC :=

EXAMPLE_SRC := main.c alt_16550_buffer.c alt_16550_prompt.c echo_prompt.c launcher_prompt.c memory_prompt.c

ELF := application.axf

# These parameters can be overriden
# LINKER_SCRIPT
# HWLIBS_SRC
# SAFECLIB_SRC

include Makefile.inc

Isn't there another easier way to do this without license?

Hi, 

I think the reason why it didn't work is because 

#MEMORY ?= ddr

MEMORY ?= ocr

For Arria 10 OCR address starts from 0xFFE00000, https://www.intel.com/content/www/us/en/programmable/hps/arria-10/hps.html#topic/sfo1429891236418.html

either try changing back to DDR or use the 0xFFE00000 address (if your application bin is smaller than 256KB) as OCRAM is quite small.

As the design is based on cyclone V, memory address might be different as well, eg Arria 10 Devkit uses UART1 so you might need to change the address to 0xFFC02100

Could you try Radu suggestion as well, and also just wanted to understand, is there any reason you wanted to use baremetal to show uart printout or whether to just boot into linux and running the hello world example?
