Bus error on memory operation

I suspect you are tring to fit a quart into a pint pot.

The 82k looks like a standard bsp build that includes a printf(), it will only fit into external memory.

Address 0x8000 is probably a small internal memory block.

You need to look at which memory areas the code/date/stack are assigned to.

Altera really ought to change the default examples to use the small bsp.

Hello,

I have a Cyclone V SoC dev kit and I get the following errors when trying to load it onto the board:

ERROR(CMD16-TAD216-NAL18):

! Failed to load "DPD_Ex.axf"

! Failed to write 82,792 bytes to address S:0x00008000 while writing block of 4,096 bytes to address S:0x00008000

! Bus error on memory operation.

Any ideas what is going on? How to fix it?

Hi,

I am trying to execute the same bare-metal program (the one described in the user guide) on my Cyclone V SoC development kit and facing same error. Here is the message :

loadfile "D:\TOOLS\altera\130sp1\embedded\ds_5_teast_wb\Altera-SoCFPGA-HelloWorld-Baremetal-GNU\hello.axf"

Target Message: Memory access caused precise abort.

Debug Precise Abort Registers : DFSR = 0x00000817, DFAR = 0xFFFF1000

ERROR(CMD16-TAD216-NAL18):

! Failed to write 16,048 bytes to address S:0xFFFF0000 while writing block of 4,096 bytes to address S:0xFFFF1000

! Bus error on memory operation.

Will you please explain me how you solved this problem?

Like, the answer given above says. Your file is too big for the space.

Yeah, that I know very well. But, what should I do to execute this bare-metal program successfully?

Hi,

I am facing same error.

Will you please explain me how you solved this problem?

Thank you very much!
