TI EVMK2H & MCSDK: Small Cell Evaluation Platform

Other Parts Discussed in Thread: RFSDK, 66AK2H14

Hello to the TI E2E community!

I am currently looking at the TI EVMK2H small cell evaluation platform (linked below) and need to make a decision on whether to purchase it and proceed with developement. The timeframe for this decision is by close of business (17:30 GMT), Wednesday 4th, February. A decision later than this date will be considered a slip in schedule so urgent responses will be very much appreciated.

The foundation software provided with this evaluation board is the Multicore SDK (MCSDK).

processors.wiki.ti.com/.../MCSDK_User_Guide_for_KeyStone_II

I have some questions relating to the small cell software overview as seen here:

www.ti.com/.../software.html

So in relation to the above, i have some questions that I would appreciate any information on. These questions are as follows.

1) I understand that the MCSDK is included with the evaluation board as foundation software. What is not clear is whether the "SoftwarePac" software, inlcuding the LTE software, is included. In the diagram shown in the overview link above it appears to be a separate package. Is this correct? or is it actually inlcuded in the evaluation board software? If not included, where is it available from?

2) TI claim that it is possible to "make first call in a few days". I would like to know what exactly is required for this? Assuming that there is the eval board (EVMK2H) and an air interface (transceiver of some kind), Is all the software required to do this included? LTE L2/3 stacks?Is the RFSDK software package related to call processing or is it only required to configure TI's transceiver interface (AFE7500)?

3) To make calls, can any UE mobile device be used or are there specific requirements/sim cards required?

4) CPRI data format in section 7.6.1 of the Keystone II Aintenna Interface 2 (AIF2) document specifies that the uplink is 7/8bits as opposed to 16bits for the downlink. Section 3.2 of this document specifies 15bit I and 15bit Q bit widths. Section 3.2.2.2.1 states again that “AIF2 supports only CPRI LTE sample bit widths of 15-bit I + 15-bit Q”. Is it possible to get clarification of this and confirm if it is possible to support symmetrical 15/16bit UL and DL?

Thanks for reading and any information would be much appreciated.

Thanks and Regards,

Dean

Hi Dean,

Welcome to the TI E2E forum. I hope you will find many good answers here and in the TI.com documents and in the TI Wiki Pages (for processor issues). Be sure to search those for helpful information and to browse for the questions others may have asked on similar topics (e2e.ti.com).

Yes. The "Base Station SoftwarPac" is seperate a package. I will assign this post to correct expert for answer. Thank you for your patience.

Hi Rajasekaran,

Thanks for your assistance, it is much appreciated.

I have just updated the original post because i should have mentioned that I need answers to these questions as soon as possible in order to evaluate whether the platform is suitable for our needs and whether we can proceed to purchase the eval board for development work. If I could recieve answers today that would help a lot and would be very much appreciated.

Thanks and regards,
Dean

1) LTE package is a license SW package for fee. In order to obtain it, you will need to contact the business team.
2) This would require the full SW stack including PHY and L2/L3 with all the dependent the platform SW, on the board that TI recommends, to make the LTE first call. The board we use is EVMK2H plus DRBOC and Marconi EVM. SW is not part of the board and needs to be downloaded and installed. All the LTE SW are licensed SW and you need to work with business team in order to get them. RFSDK is only required if you use TI EVMK2H+DRBOC+MARCONI.
3) There are specific bands that RFSDK is tested with, so if using TI platform, the UE needs to support those band.

Not sure if you have a local sales person or not. But in any case, the TI contact would be Sneha Narnakaje nsnehaprabha@ti.com .

Thanks a lot for you help! Just one question about your previous answer before i mark it as verified. you mentioned the LTE SW is a licensed SW. Is this one SW package for L1, L2 and L3? All the SW required for making calls? Or are L1 and L2/3 separate SW packages?

Thanks and Regards,

PHY and stack will be seperate packages and offerings.

If I understand correctly, EVMK2H hosts one of 66AK2H14/12/06 chips, none of which have wireless accelerators (TCPs, FFTCs, VCPs). Is it still suited for LTE PHY processing, and does it work with TI's LTE PHY software stack?
