Beagleboard-XM memory chip

Hi,

Does anybody know what is exact part number of Beagleboard-XM's MDDR
SDRAM?

For A2 the bom has two options:

MT46H128M32L2KQ-5 IT:A (Micron)
JZ58F010600Y040 (Numonyx)

If it is Micron it will look something like this with a shorthand code instead of the whole number.

Thanks a lot.. I want to put memory used in beagleboard revC4 on top
of beagleboard-XM since it has both nand and sdram and cheaper. do you
any idea how to change kernel or u-boot, so that system recognizes
nand and boots from it

That's not a trivial operation. Assuming you could somehow expose the
NAND part, you could modify U-Boot to talk to it, and the kernel, but
it's kind of one of those things where if you have to ask, it's probably
going to take a long time to do it.

Jon.

What do you want to do?? I don’t think it is possible.

First: realize the part related to the HW
Second: ask questions about SW.

I believe this the waste of time discussing how to change u-boot while changing the PoP memory is barely possible.

Thanks for quick replies. I need it for a product. I am not going to
replace POP memory which is on my BB-XM, instead I want to manufacture
a board which is exactly same as BB-XM, with a MT29C2G48MAKLCJI-6 IT
in place of MT46H128M32L2KQ-5 IT:A.

The chips are pin-compatible, so there is no issue there. You may
have to modify x-loader to recognise the new combination of OMAP/board
and RAM. I don't remember how the detection is done.

Thats a good news for me!!! will try and if successful I will post
here

venki,

are you a dreamer? Do you know how difficult to assemble such kind of boards? Do you know that such technologies like PoP are mostly available for strong mobile vendors because they have huge budgets and are able to cope any demands? You ask so simple questions and even didn’t have a glance into documentation for beagleboards which is available publicly. I think you even won’t be able to get real documentation for these types of memory from Micron. They do not provide the documentation for these chips indiscriminately.

I can only wish you luck in this affair.

Maxim,

thank you for your reply. I really know very less about these
technologies as I am very new to this. I thought that it would be very
simple. Do you mean to say mounting pop memory on a DM3730 is
impossible. I will be very helpful if you explain a bit.

venki,

I didn’t meet impossible tasks. But every task has a time and budget limits. This means that if you don’t have enough money than mounting even DM3730 itself can be impossible. I just want to warn you that FR4 for DM3730 will cost a LOT! Next you will have to find some assembly company which is able to mount such chips.

Why do you think the whole world buys ready Beagleboards and does not assemble them? All hardware related files are open, download them and begin the production. Simple? Yes, but it requires a loooot of money
