Thank you.

Do you mean the bleeding edge 4.8 tool chain or another?

Do you use a different IDE or command line?

Thanks for the info.

I don't see it. Can you provide a link?

Thanks.

You and mculover definitely nailed down the problem and pointed me in the right direction. I didn't touch the board definition files but I changed my code slightly and now it works fine. palSetPadMode(GPIOA, 4, 0 ); palSetPadMode(GPIOA, 5, 0 ); palSetPadMode(GPIOA, 6, 0 ); palSetPadMode(GPIOA, 7, 0 ...

On, second thought, it sounds like the problem might be with the pins that I am not using and noth with the ones that i am using.

I'll play with this some more.

I had a peek at board.h and changing that seems a bit daunting.

Shouldn't the pin configuration applied in my code be sufficient to override what is defined in board.h?

It can be found in the boards directory of the ChibiOS distro.

Here is the demo. Compile it and connect terminal to USART3(PC10 - TX | PC11 - RX) Jumper PA6 to PA7 to loopback SPI1 MISO and MOSI. Execute the program and what is typed in the terminal should get looped back to the terminal via the SPI1 module. Then comment out the line reading: #define TEST_WORKI...

I'll try to work up a simple demo and upload it.

Thanks.

Yes, The CS pin is programmed as GPIO.

I suspect if that were the problem I would see different results since TX seems OK but RX is not working even though the SPI slave device is responding appropriately.
