Download Elf Process failed

Could you provide some more details about your setting? Such as configuration of your clocks, of the NIOS (including used RAM for data- and for instruction-master).

Maybe as screenshots?

The first things I would look on are:

- clocking

- resets

- working RAM (in case of DDR and SoC you need to enable the FPGA->SDRAM-Bridge)

Hi,

Thanks for an early reply.

I am trying to run the Video and Image processing design example on cyclone V soc. The pin mapping are -

set_location_assignment PIN_AD27 -to reset_n

set_location_assignment PIN_AK21 -to ddr3_reset_n

set_location_assignment PIN_AC18 -to phy_refclk

set_location_assignment PIN_Y26 -to clock_source

I am using external PLL.

Do you also have screenshots from the whole QSYS-System?

Why do you use NIOSII Gen2?

Hi,

Issue solved. I was facing problem with pin assignments.

But elf downloading still fails and its actually very wierd behaviour.

Here it is when i try to download elf from command line -

I AM trying to download elf and sometimes it fails and sometimes it pass. Also the verify fails at different addresses and not any one particular.

Somebody please tell me why this is happening.

Is your system timing-clean?

--- Quote End ---

TimeQuest timing analyzer has given no errors and it is showing successful. Although there are some warning messages.

What else to look for to ensure system timimg is clean or not??

--- Quote Start ---

Could post a screenshot of the timing analysis report?

--- Quote End ---

I am attaching the following snapshots -

1.give no errors in Timequest timing analyzer ang shows it successful

I can see slack issue in the clock source in above. Is this the cause for the issue?? And if it is how to get over it?

Thanks again !!
