Hi
I am using MCIMX6U8DVM10AB dual lite processor and have interfaced MT29PZZZ8D5BKFTF-18 W.95L to the processor.
When i am writing any of the data to the any address of memory it is written to all the address lines.
What may be the possible reason for this.
Regards
Nitesh
Hi
Our concern is like data gets written to all the address line even though I am writing the data to only one particular address.
If there is a short or some manufacturing issue it will not write to all the address lines.
Also we are reading or writing through the JTAG.Is there some register settings we are missing out.
Regards
Nitesh
you can check your jtag register settings with
Sabre reference board, if read/write are ok, then problem
in your board only.

Hi Igor
Thanks for prompt reply.
I am attaching the JTAG register settings for your reference what we are using for our board.
Please let us know if something is missing out.

Hi Igor
The document attached is for DDR3.
But our application is LPDDR2.Please find our attachment that we have sent and please verify all the settings. We have tried all LPDDR2 settings available in Freescale site. It’s not working.
Can you please verify our LPDDR settings.

Hi Igor
Thanks for the reply.
Could you please confirm that the pin DRAM_RESET pin must be pulled low or it can be NC also.
With Regards,

it can be NC as in i.MX6SL EVK schematic

Hi igor,
i am not able to reset the lpddr2 through the script provided by freescale as nitesh is saying.
can you let me know how to read the mode register from lpddr2 so to make
sure whether communication from lpddr2 is happening or not or else
what is the command to verify through which i can assure that my lpddr2 is reacting to
the command triggered from trace32 or not.

Hi Nitesh
reason may be schematic or layout errors (broken, short circuit traces)
so actually one address is read/written. Recommended to read/write with jtag,
checking signals with oscilloscope.
Best regards
igor
