Defference between EVMK2H and EVMK2H"X"

RY9983

Other Parts Discussed in Thread: 66AK2H06, 66AK2H12, TCI6636K2H, TCI6638K2K

Hello.
What is the difference between EVMK2H and EVMK2H"X" ?

My understanding is:
EVMK2H"X" is superset of EVMK2H. Is that right?
I would like to clarify if there are any restrictions to use EVMK2H"X".

Hi RY,

EVMK2HX - (EVMK2H Evaluation Module + XDS560V2 External Emulator)
The K2H EVM comes with XDS200 onboard emulation capability. In addition, an external emulator via JTAG emulation header can be also be used.

EVMK2HX features their embedded JTAG emulation with USB Host interface via XDS560V2

Hi RY,

I had doubt after above post then i checked with team. Sorry for providing the wrong information.

We don't have documentation on the difference between EVMK2H & EVKM2HX as it would only be 1 sentence. The only difference is that EVMK2HX has the DSP silicon where the encryption features is e-fused "ON". Everything else (PCB, other components, features etc) are the same.

Thank you.

Rajasekaran-san,

It's all right.
Can I disable encryption features by software?
Because, we do not need it.

Best regards, RY

RY,

EVMK2HX stands for the K2H family including 66AK2H06 and 66AK2H12 which have different number of DSP and ARM cores, 4+2 and 8+4.

and EVMK2H is TCI6636K2H which is 8+4. The different namings, TCI66 vs 66A, mean for different markets.

Rex-san,
I am confusing.

My understanding is:
EVMK2H"X" .. 66AK2H12/06 is implemented.
EVMK2H .. TCI6636K2H is implemented. (Is it typo of TCI6636K2"K"?)
Is that correct?

I think EVMK2H"X" includes TCI6636K2K.
What do you think?

Best regards, RY

Hi, RY,

I am glad that you are thorough on this and bring us to somewhere we never pay attention to. Internally, we had some confusion as well. It turns out that the "X" means the Security Accelerator enabled. So, K2H does not have SA.

By the way, 6636 is a K2H (generic name not considering X or not) and 6638 is a K2K.

Rex-san,

It was cleared from your reply. Thanks!!

K2HEVM .. 66AK2H12 and 66AK2H06 without SA
K2HEVMX .. TCI6636K2H with SA
XTCIEVMK2X .. TCI6638K2K

Hi RY,

From my understanding,

K2HEVM - 66AK2H12/66AK2H06 without SA

K2HEVMX - 66AK2H12/66AK2H06 with SA(e-fused "on")

XTCIEVMK2X .. TCI6636K2H/TCI6638K2K with SA(e-fused "on")

I am planning to write e-mail to EVM667xsupport@advantech.com to get this information. I will post back, if i get any response from them.

Thank you.

RY,

Raja's unsderstanding is correct. They may be the same part number, 66AK2H12, but different EVMs with or without SA (EVM or EVMX). All TCI part numbers have X with SA enabled.

Hi,

Our project target platform is based on TCI6638K2K .SoC. We need to buy an EVM for TCI6638K2K for software development till we get the custom board . we are not getting right information on the TCI6638K2K evm part number..

As the TCI6638K2K tools and software link leads to following option

TCI6636K2H Evaluation Module

TCIEVMK2X

Evaluation Modules & Boards

that basically mean TCIEVMK2X has TCI6636K2H SoC and not TCI6638K2K, If that is true either there is no EVM for TCI6638K2K. or the evm part number for TCI6638K2K.SoC is different. /the TCIEVMK2X part no has two variants one with TCI6636K2H. and other for TCI6638K2K (may be custom made for few customers)

Please clarify what SoC does TCIEVMK2X evm has TCI6638K2K (http://www.ti.com/product/TCI6638K2K/ ) or TCI6636K2H (http://www.ti.com/product/tci6636k2h?keyMatch=TCI6636K2H&tisearch=Search-EN-Everything ) ?
