SDK Tools using DK-USB-SPI-10225-1A

Hi,

We are using CSR1010 chip in a custom PCB design for a simple battery powered bluetooth application. For this we are buying the DK-USB-SPI-10225-1A USB-SPI programmer from DigiKey. This will require sdk bin tools on the host computer to flash the program (such as e2cmd).

However, after searching on the forums and docs, we have found the only way to access the sdk and xIDE tools is through buying the CSR1010 dev kit which contains the access codes. This is very pricey and we wish to move forward with production, we dont need a dev kit just the sdk and tools. Is there a way to get these so we can use the programmer without buying the dev kit?

Any help would be appreciated, Thanks!

Hi,

Without the SDK and relevant tools and documents the chips are of no particular use. Not sure on how you plan of developing the end product even without making a prototype on a devlopment kit.

The question is, from where are you getting the CSR1010 modules or chips? What is you production plan? How do you plan to calibrate the modules?

An alternative way which I could suggest is to use a design house who already have the CSR SDK and can help you with their resources and experience for a fee.

Let me know your thoughts.

Regards,

Thanks for the quick reply!

We were planning to source the CSR1010 chips from DigiKey part number CSR1010A05-IQQM-R. The PCB design is based on the example application schematic provided by Qualcomm in the CSR1010 datasheet. So, the debug SPI pins from the IC are connected to a JTAG on the PCB through which we were going to program it. From your answer, I understand that buying a dev kit would our only option unless we go with a design house, right?

Also, could you elaborate on the mention of design houses? How could we contact them and what fee would they charge? Thanks a lot for your help.

Developing production quality RF modules might take a few iterations. Based on the regulations you would also need to go for a BT SIG certification of the design.

Its generally better idea to purchase a qualified module form a vendor than make your own custom HW, if your volumes are low. The module vendors can also help you identify design houses.

I see. We wanted to create our custom PCB to be more cost effective and ensure security. I will discuss the points you mentioned with my team. Our production numbers are not expected to be high hence as you stated it might be prudent for us to use a vendor designed model. Thanks a lot for your suggestions and advice!
