Hi Alex

I am using the hwlibs examples located here:

https://www.rocketboards.org/foswiki/Documentation/HWLib#Running_Cyclone_V_HWLib_Example

Please find the binaries attached.

If you could also send me your copy that would be great.

I see that the steps that you are using is slightly different from mine.

The steps of creating the binary, i am using the command below:

"arm-eabi-objcopy -O binary application.elf application.bin"

The application should be in .elf instead of .axf.

You can change the Makefile line 54 to "ELF := application.elf".

Regards

Jingyang, Teh

Hi,

Update 2

I used the objdump to check the elf file,it shows the entry address is 0x0100_0060，

and your elf is 0x0010_0080(which make sence for it need 0x40 header from mkimage),

I didnt change the linker file or other settings except the "." from 0x0010_0040 to 0x0100_0040,

if MY ASSUMPTION is correct,the start address of my elf should be 0x0100_0080 INSTEAD OF 0x0100-0060.

Do you know why is that?
