warning with on chip memory data items width

Hello,

I am trying to convert the preloader from ELF to .hex to boot the HPS of a Cyclone V from the FPGA.

(cf https://rocketboards.org/foswiki/documentation/bootfromfpga140 ), with a DE10-nano board.

However, I got warnings : Warning (113015): Width of data items in "preloader.hex" is greater than the memory width. Wrapping data items to subsequent addresses. Found 1148 warnings, reporting 10

So according to this thread, I ned to make match my memory data port width ( 8bit) with the record length.

I do not have a mem_init.mk file on my computer,

just a makefile to compile the preloader.

The command to convert to hex file is :

arm-altera-eabi-objcopy -O ihex --adjust-vma -0xc0000000 uboot-socfpga/spl/u-boot-spl preloader.hex

I am using Quartus 17.1.

is there is a argument I can use for arm-altera-eabi-objcopy to set up this record length ?

The website https://manned.org/arm-none-eabi-objcopy lists and explain the command, but the only one I saw is interleave-width and it do not seem solve my problem.

Could you help me please ?

Regards,

Neudorf.
