SPI Interface

Questions and discussions related to Inforce 6540

Dears,

How can I use the SPI interface via BLSP2 (BLSP 1 QUP 1) with GPIO PIN 4~7 when I get a new IFC6540 board?

Some PATHs and FILENAMEs mentioned in a specification can not be found.
Does someone can show me how to do step by step?
That would be very appreciated.

Hello,
On the Inforce 6540 SBC, BLSP2 (4 lines)are made available on the expansion header through pins 2,4,6 and 8(GPIO pins 4~7 respectively). Please refer to the document titled 'APQ8084_Configure_BLSP_Port_ApplicationNote_002308_Rev_E.pdf' available on Inforce Techweb (http://www.inforcecomputing.com/techweb/) for instructions to program the BLSP lines to SPI. Hope this helps.

Cheers,
Sundeep
