Renesas SPI (RSPI) + SD-card

[vadim_ova]

Hello to everyone!

I have a problem with my controller - SH7216. it has RSPI (embedded SPI) and i try to initialize sd-card. it doesn't answer at all)))) although I've tore into real all the advices i had been given...... I've set all the phases and polarities.... bitrates and bytes....

and questions

i don't know, whether it normal, that at MISO line is a high level (3.3v) even if a card is ejected from card-holder. What can you tell me? thanks.

Hi

Go to Renesas site and down load a code that use the SPI hardware

Use this code to access the SD card

try to put program in never ending loop for writing a byte using the SPI port

Look at the signal using a scop

All the best

Hi Vadim,

maybe it's this Sample Code?:

"Using RSPI in User Program Mode Application Note"

Did you figured out how to access the SD-Card?
