Hello all,
my design holds microSD card (working with emfile) and Serial RAM (connected to the same SPI lines as microSD card).
My question is how can I assign same pins to both emfile and SPI Master?
Whenever I set pins for emfile (in Pin Editor), pins for SPI Master get deselected and vice versa. Is there something basic that I am missing?
Regards

The datasheet for the emFile component states that the pins are not accessable. To find a way out you''ll have to ask Cypress.
Create a MyCase (Top of this page Support&Community -> Technical Support -> Create a MyCase)

PS Would be kind if you keep us informed.

Oh, there WILL be an answer. So far as I can see the only way out will be to re-write the emFile component to gain access to the "buried" pins. Did you already have a look into the "Component Author Guide" to become comfortable with the process?
Additionally there are some videos concerning that matter: video.cypress.com/video-library/search/component/

Hello,
problem solved by awesome Cypress Support, not even that they suggested solution, but they modified the emFile component accordingly and send it to me (and I was already prepared to waste certain amount of time to figure out how to modify component).
With modified emFile component (MISO, MOSI and SCLK pins revealed), it is just a matter of couple of multiplexers / demultiplexers to select which device(SPI) will be active.
Modified component is in the attachment.
Best Regards

Hi, please, can you post the modified sourcecode here. No attachments ..... Do not use Chrome, upload problems persist.
