Using ECC

Hi,

I would like to know how to use the ECC.

First, I tried to add writel() code to the ddrc.c file. but booting is stop at writel() function.

And then, I modified memory according to the Zynq-7000 All Programmable SoC Technical Reference Manual. but board was not booted with red led (D17, D18).

How can I use the ECC?

Regards,

Hello Hyeonsu.kim
What board are you trying to target? What operating system are you using? What tool set are you using, Vivado or SDK and what version?
I also found a few articles that you may find useful.

Thanks Josh,

I already saw that article. But it was not useful for me.
I want to use the ECC without using FPGA.
Do you have any ideas?

here my target and tool
target board
- 7015 SOM
- FMC Carrier Card
tool
- petalinux2015.2.1 (SDK)
