Hi,

AM4376 is 32-bit Process So, Can I connect 4 GB DDR3 RAM with it? because I come to know in project cms file, Memory allocated is 2 GB for RAM as below.

#ifdef A9_CORE     /* A9 memory map */
MEMORY
{
    SRAM:     o = 0x402F0000 l = 0x00010000 /* 64kB internal SRAM */
    L3OCMC0: o = 0x40300000 l = 0x00010000 /* 64kB L3 OCMC SRAM */
    M3SHUMEM: o = 0x44D00000 l = 0x00004000 /* 16kB M3 Shared Unified Code Space */
    M3SHDMEM: o = 0x44D80000 l = 0x00002000 /* 8kB M3 Shared Data Memory */
    DDR0:     o = 0x80000000 l = 0x80000000 /* 2GB external DDR Bank 0 */
}

Please reply ASAP.

regards

Hi,

For supported memory configurations please see section 5.12.8.2 of the AM437X Datasheet Rev. B. The maximum supported DDR memory size for AM437X processors is 2GBytes.

Hi Biser Gatchev-XID

After referring the datasheet, I have gone through the different types of connection between DDR3 and AM4376 ( 2 nos, 4 nos etc)
I want to connect single 2 GB DDR3 RAM with AM4376, but not able to find/understand the connections for it.

Will you provide connections/interfaces or explanation to help to get it done.

Best Regards
Bhavdipsinh

See Table 5-50. I sincerely doubt that you will find a 2GByte 16-bit DDR3 memory. The largest I know of are 512MByte.
