The sample of SPI on C6748 LCDk.

user4730642

I'm sorry my English is not good .My company bought a board of C6748 LCDK, and I use is that you provide the sample code.The address is:C:\ti\C6748_StarterWare_1_20_04_01\examples\lcdkC6748\spi .I have the code will burn to we in the design of the circuit board.Our board is modeled after you give the schematic diagram of design.After burning,SPI_SIMO on the oscilloscope have no reaction, because of your C6748 LCDK board SPI1 connection to J16. I don't have that kind of adapter plate.I will change SPI0 SOC_SPI_1_REGS and some other parameters, burn to LCDK development board, the result is the same, I have already connect 0 ohms resistors for R214,R215,R216 and remove R184,R179,and R178....What reason is this excuse me?

This SPI example is for finger print sensor which is not populated in latest LCDK boards, so you won't get any result but you could see the signal.
Please make sure that you are probing the correct points.
For SPI1_SIMO, you can try to probe J16.36 pin.

Do you have Debugger (JTAG) ?
Please try to run the code through JTAG.

Dear Sivaraj K ,

Thank you for your reply.

My purpose is to use C6748 SPI interface.First of all, I will SPI routine burn to C6748 lcdk.Then I use an oscilloscope to J16 36-pin (SIMO) acquisition.Then without any signal collected, this is my question.

Dear Haidong,
I would like to suggest to debug the code then try to flash it on SPI flash.
Please make sure that your code is running and booting.
