DDR3 of ECC/TWR-VF65GS10(rev.G).

Hi,

 

I use TWR-VF65GS10(rev.G).

And I use ECC option of DDR3.

 

I tested DDR3 in 'ecc_tests.c' which I attached. And there is no error.

 

The 'twrvf65gs10_ddr_ecc.mac'file which I attached is macro of IAR EWARM.

I carry out this macro before carrying out Program in DDR3.

However, Program is hung up on the way.

 

I want to know the reason.

 

Q1)

When I use ECC option of DDR3, is the setting of the 'twrvf65gs10_ddr_ecc.mac' file which I attached right?

Q2)

I enabled ECC option of DDR3, and have you moved Program? Or have you carried out Program such as U-Boot?

If there is Program at that time, give me it.

 

Best regards,

soichi

Hi,

How about after that?

I want the answer to following question earlier.

Q2)

I enabled ECC option of DDR3, and have you moved Program? Or have you carried out Program such as U-Boot?

If there is Program at that time, give me it.

Best regards,

soichi

Hello Soichi,

I don't understand your prior question; Timesys Vybrid support assumes U-boot is present, Linux is running on the Cortex-A5, and MQX is running on the M4. An example of this for the Vybrid Tower is available at linuxlink.timesys.com - login with your user account, click on "Download BSP/SDK" and download the MCC demo for the Vybrid Tower. This includes a ping-pong demo described in the Vybrid MCC USer guide at the following page:

https://linuxlink.timesys.com/dev_center/freescale_vybrid

With regards to ECC in DDR, this is not currently supported, and at this time we do not have plans to do so; this thread provides some further information:

Hello Timesys Support and Karina Valencia Aguilar,

Thank you for an answer.

In some threads, I perform only the memory test of the ECC function of the DDR.

And I carried out the memory examination, too and was a success.

I referred to the following thread.

https://community.freescale.com/message/506001#506001

I enable ECC function of the DDR.(SRAM) And I load test Program for DDR. I operate test Program.
I tested the above.

However, I failed in movement.

Therefore I investigate it.

Q1)

Does the ECC function of the DDR support it in TWR-VF65GA10?

Q2)

>  I enable ECC function of the DDR.(SRAM) And I load test Program for DDR. I operate test Program.
>  I tested the above.

Plaease give me some advice In the test mentioned above.

Best regards,

soichi

Hello Soichi,

Q1) DDR with ECC is not supported in Vybrid at this time. Please refer to the thread you link to, #506001

Q2) We will attempt to enable this in Uboot and test; if that proves to be functional, we will provide the necessary changes.

Hello,

soichiyamamoto​ and karinavalencia​ - we have determined which registers need set and will be booting and testing shortly; assuming U-boot is functional/bootable, we will pass that along.

Hello karinavalencia​ and soichiyamamoto​,

We have determine what registers need setting, but boot testing of U-boot with this enabled has not yet been completed.

I am hopeful we can pass something a long before the holiday.

Hello soichiyamamoto​ and karinavalencia​,

Attempts to set the necessary registers to enable this resulted in a hanging U-boot. Unfortunately, as this is not supported, per previous threads requesting ECC enabled DDR, this will need to be investigated as a dedicated engineering effort and cannot be further investigated in this thread.

Karina,

This looks to be IAR, which we are not able to support; soichiyamamoto​ - you are using IAR in this case, correct?

Thank you,

Hi,

Thank you.

Yes, it is IAR macro.

If it is macro of DS-5, will you support it?

Best Regards,

soichi
