Part Number: TDA2EVM5777

Dear,

There are something about TDA2EVM5777 platform.

I have bought EVM board of TDA2EVM5777 ,

if we want to sign NDA, it is free for NDA signature?

our board is EVM5777G-03-40-00,

What is the address range of DDR?

I browsed through the specification generally, there are EMIF1 and EMIF2 in this main chip,

could you tell me how about this board for EMIF interface,only one emif interface used,or both?

BRS,

Meng

Hi Meng,

1. You should contact your local TI representative to get more details about NDA.
2. TDA2EVM5777 has 4GB DDR3L SDRAM. The MPU (Cortex A15) is able to access all 4GB but for other SoC masters only 2GB are available. In other words, you have 2GB shared among the system and 2GB MPU-only memory. These 4GB are spread across both EMIF1 and EMIF2 - 2GB per EMIF.

Dear Dobrin,

Thank you for your reply.

your meaning：

In Tda2x SOC，cortex-A15-0 and cortex-A15-1 can access 2GB memory, the other cores in this SOC can access another 2GB DDR memory

My understanding is right or not?

Thanks in advance.

Meng

Meng,

I mean, the other cores can access 2GB, Cortex A15 can access the same 2GB and also another 2GB visible only by the MPU(Cortex A15). So, MPU can access 4GB, and all other SoC masters access only 2GB.

Hi Meng,

Cortex-A15 can access all 4 GB.

Other masters can access only 2 GB.
