Is not setting the DDR_4_BANK value to 1 when 4 banks is selected.  Is this a bug in the script or should the value really be 0?

[LinWang]

Would you please show which LPDDR2 part support 4 bank?

Please share the Datasheet with me.

Thanks!

Hi LinWang,

I found this script aid cannot select "8" for "Number of COLUMN Addresses" in Register Configuration sheet even though i.MX6SL can set it to "8 bits column" according to IMX6SLRM Rev.2 Chapter 32.12.1.

So Would you fix the bug?

Best Regards,

Hi Satoshi,

Yes, i.MX6SL can support it.

But the die desity range from 2Gb to 8Gb which supported by this aid don't need support it.

HI LINWANG

             how can I get the password of the document

I will not share password out.

I will corrrect it.

Thanks!

Hello Lin,

We have a custom board with an LPDDR2 512Mb.

The i.MX6SL LPDDR2 Script Aid doesn't support this density.

Is there any way to specify the correct density into the script or another way?

Regards

[LinWang]

Hi Yakov Shaulov,

Thanks for attend the aid!

As 512Mb is not popular application for i.MX6SL, I did not inculde it into script aid.

I believe the only way is referring to i.MX6SL RM and modify script manually.

I can help if you have specific question.

Hi Lin

How to config 1Gb capacity DDR2 parameter in "Mx6SL LPDDR2 Script Aid V0.06"?

Thanks.

[LinWang]

Hi Felix,

1Gb is not in my aid scope.

You can refer to current aid and develop 1Gb script by yourself.

The prime differences should be seen by comparing different between 2Gb and 4Gb.

Hope it can help you!

Hi Lin

I had compare the 2Gb and 4Gb setting .inc file, only CS0_END(0x021b0040) is different, but I can't understand calculation formula.

How to calculation the CS0_END?

2Gb setting:

setmem /32 0x021b0040 = 0x00000047 // Chan0 CS0_END

0x47-0x3f = 0x08, 8*32M = 256M

4Gb setting:

setmem /32 0x021b0040 = 0x0000004F // Chan0 CS0_END

0x4F-0x3f = 0x10, 16*32M = 512M

1Gb setting:

setmem /32 0x021b0040 = 0x0000004F // Chan0 CS0_END

1024/8=128, 128/32 = 4, 0x4+0x3F = 0x43

Is the above correct?

Thanks.

Here is formula: 4*DRAM density per CS (Gb)+63
