SPI Loopback example for Concerto not working

Kumar Nega

Other Parts Discussed in Thread: CONTROLSUITE

Hi All, I am having problem with SPI loopback example for Concerto (C28x). I'm running example code from control suit project name spi loopbaack (without interrupts). I don't see any changes in the register values in the watch window. As per the description, external connections are not required. Could anyone help me out what steps I need to follow. Please have a look at the screenshot.

Hi Kumar,

As the header describes:
This program is an SPI example that uses the internal loopback of the peripheral. Interrupts are not used. No external connection is required.
is very true.
By running this code directly you can watch the transmitted and received arrays real-time. Btw your continuous refresh button seems to be switched off. Simply turn it on.

Regards,
Gautam

Hi Gautam,

Thanks for your reply. I have tried by switching continuous button but did't work. Other C28x example works fine but I don't know what's wrong with this example. Initially I'm trying to understand this example, later I need to communicate with external module. Am'I missing something here?

Regards,
Vinod!

Vinod can you tell us from which path did you import this example?

I have imported from controlSUIT - C:\ti\controlSUITE\device_support\f28m36x\v100\F28M36x_examples_Control\spia_loopback\c28.

Actually while build I got this error :
C:/ti/controlSUITE/device_support/f28m36x/v100/F28M36x_headers/cmd/F28M36x_Headers_nonBIOS.cmd", line 192: error.
I tried with other specific cmd files but got errors . So, I removed the .cmd file and replaced it as none. Then I build it without any errors, but not able to debug it. Is it fine to replace it?
