Other Parts Discussed in Thread: 66AK2H06, 66AK2H14

Did the Keystone II test with 8GByte DDR3 memory?

If yes, could you tell me the detail info of the 8GB memory?

We want to by one for testing.

Thanks.

Hi Zhigang,

We have tested the K2K and K2H devices with a 4GB and 8BG dual-rank UDIMMs. The Micron MT18JSF51272AZ-4GB and the Kingston Technology 996 5525-024.A00LF are both JEDEC compliant dual-rank DDR3-1600 UDIMM modules. Both of these have been tested with the KeyStone II devices.

Hi Bill,

Thanks for you reply.

I tried to run u-boot with a 8GB Kingston DDR3-1600 on Keystone II, but it can't boot up.

Is there any modification needed in u-boot?

Zhigang

Bill-san,
I am evaluating 66AK2H06.
Although I am looking for the "Kingston Technology 996 5525-024.A00LF" in the Kingston site, I can not find it.
(http://www.kingston.com/us/memory/search/options/)

Is it the special parts provided only for specific application?
For general application, we need to use Micron parts. right?

Best regards, RY

RY-san,

My apologies, I posted the wrong number for the Kingston device. The part number should be KVR16E11/8. I accidentally posted the module assembly number.

Thank you, Bill-san.
Sorry. Since the verify answer button is not appeared for some reason, I send you message.

Bill,

The KVR16E11/8 is 240-pin, but Keystone II can only use 204-pin memory.

I tried it with KVR16S11/8, but the u-boot can't boot up on Keystone II.

Zhigang

Hi Zhigang,

The memories that I listed were used on a different test platform which has a UDIMM connector. That test platform was used for DDR3 memory testing with different memory topology when paired with the KeyStone II device. The part number you listed is an SODIMM which is the format used on the EVM. The EVM was designed to use x72bit DDR3 SODIMM modules which are not pin compatible with x64bit SODIMMs. Since the Kingston device you referenced is a x64bit SODIMM module it will not work if installed on the EVM. I am not aware of any 8G SODIMM modules that have been tested with the EVM but I will check with the manufacturer.

Hi Zhigang,

The Micron MT18KSF1G72HZ-1G6E2ZF has been tested with the EVM. This is the only 8G memory module currently supported by UBOOT on the EVM.

Hi Zhigang,

The link below will take you to a file with the 8G SODIMM configuration for the above module on the external git repo.

Hi Bill,

I am sorry if I am sort of hijacking this thread. I am having the same problem with CT102464BF160B.C16 8 gb sodimm non buffered and non ecc. So do you mean this wont be supported by the k2hk emv board then ?

Hi Sambit,

As I described earlier in the post, the x64bit SODIMM connector pinout is not the same as the x72bit SODIMM connector. The K2H and K2E EVMs were designed to use the x72bit SODIMM modules and do not support x64bit SODIMM modules.

Bill

Hi Bill,
Thanks for the reply.
So the k2hk board doesnt support non ECC DIMMS ?
I went through the datasheet for the k2hk evm and I found the following.

The 66AK2H14/12/06 includes one 64-bit wide, 1.5-V DDR3 SDRAM EMIF interface.

Standard DDR3
SDRAMs are available in 8-bit and 16-bit versions allowing for the following bank topologies to be supported by the
interface:
...
...
...
• 64-bit: Eight 8-bit SDRAMs
...
...
...
which seems to imply that the SODIMM should work with this. My board is 66AK2H14. What do you think ?

Sambit

Hi Sambit,
You are looking at the data manual for the K2H component and not the technical reference manual for the K2H EVM. The limitation is not due to the K2H component. The K2H can support x64bit without ECC or x72bit with ECC. The limitation is due to the pinout of the SODIMM connector on the K2H EVM board. Unlike UDIMM connectors, the pinout of SODIMM connectors is different for the support of x72bit SODIMMs and x64bit SODIMMs. The board can only be designed to support one type or the other. We decided to support the x72bit SODIMM pinout for the connector so only x72bit SODIMM modules can be used.

Bill
