i.MX53 DDR test - ack failed

Hello All,

I am running DDR test application from Windows using the following command on a i.MX53 QSB development board:

C:\DDR> DDR_Stress_Tester.exe -t mx53 -df MX53_TO2_DDR3_LCB_SMD_ARDb.inc -com 1

It works fine. Whereas, when I run the same for the customer board the command fails with the following errors:

C:\DDR> DDR_Stress_Tester.exe -t mx53 -df MX53_TO2_DDR3_LCB_SMD_ARDb.inc -com 1

rom_check_hab: reading ERROR ack failed 0x00000000

rom_check_hab() failed

Is this because I am using the wrong initialization file (inc) or it this a hardware issue? How can I debug this issue?

Regards,

Ruchi

The mentioned "rom_check_hab" messages relate to interface between internal iROM

bootloader of i.MX53 and an application, that tries to load and run (memory)

tests  via i.MX53 UART / USB serial boot mode. There are two possible causes of

the issue.

1. The board does not start in the bootstrap (serial download) mode.

2. There is no serial connection between a PC and the i.MX53 board.

Please check.

Hello,

Thank you for your reply. I verified the custom board setup:

- It is not a Serial to Serial cable issue, I have verified the cable with another setup.

- The board is in serial download mode. I tried the following:

  a. Used the on-board button to enter serial download mode.

  b. To double check I also did a NAND erase so that by default the board will enter serial download mode.

Even after (b) I was not able to get the DDR test tool to work. I am getting the same error on the custom board I used.

Any other checks to debug this issue? Is there a log at DDR tool side (Windows) or on the board which I can enable to see what is happening?

Regards,

Ruchi
