T2081 - CodeWarrior

[juergene]

Hello community,

i have some trouble with CodeWarrior and T2081 CPU.

I am trying to valid the DDR with the DDR-configuration (CodeWarrior).

But when i start a DDR-test it failed everytime and the CCS say this:

CCSAPI connection #1 accepted from ELSTJ-W.tq-net.de at Thu Apr 12 11:40:21 2018

error: T2080: HRESET occurred during transaction

Can anyone help me please.

Thanks in advance.

Best regards,

Hello again,

i think i have the issue fixed. It was some HW issue with HRESET.

But after this i have the next failure with DDR initialization.

"Error configuuring the target! - DDR initialization failed: D_INIT was not cleared by hardware!

Can anyone help me with this.

Thanks in advance.

Best regards,

Hello Juergen,

Please check whether the RCW configuration is valid for DDR clock configuration.

Please refer to AN3940 - Hardware and Layout Design Considerations for DDR3 SDRAM to check DDR hardware design.

If there is DDR SPD on your custom board, please use reading from SPD to create a QCVS DDR project.

If there is no SPD on your target board, please create a QCVS DDR project  with the default configuration and configure the DDR related properties in the DDR QCVS project according to the DDR datasheet, then generate the initial DDR controller configuration and connect to the target board to do optimization and validation.

For details, please refer to DDRv user manual https://www.nxp.com/docs/en/user-guide/QCVS_DDR_User_Guide.pdf?fsrch=1&sr=10&pageNum=1.

If your problem remains, please also attach the CCS console log.

Thanks,

Yiping

Hello Yiping,

thanks for your help.

In the meantime I have found the problem-source.

It was a reset-timing that occured with the Codewarrior.

Best regards,

Juergen
