Hmm no noticeable errors. You can double check the kernel, on the booted device for the spidev support: Jonathan Cormier

I added the boot log for the ECC errors also. Fred Frantz

Hope this helps. Fred Frantz

JC 03:15 PM Software Development: RE: Spidev issues

Can you attach the bootlog for the device? Jonathan Cormier

FF 03:09 PM Software Development: RE: Spidev issues

It looks like it is enabled to me.

A pinmux conflict would likely cause the device not to work but it would not affect the creation of the spidev device file.
You need to make sure that SPIDEV is enabled in the kernel. It doesn't look like it is by default. Jonathan Cormier

FF 01:33 PM Software Development: Spidev issues

The dev kit baseboard file has been modified to include a "spidev" device, and the kernel was compiled to include the SPI device driver for users. However, the expected /dev/spidev0.1 file is not generated. Can a pinmux conflict with o... Fred Frantz

After the links were corrected on my system, it works using iproute2 also.
Thanks Fred Frantz

Apparently the filesystem ip utility isn't using busybox. Jonathan Cormier

JC 04:37 PM Software Development: RE: SocketCAN configuration

It would be the busybox that comes in the TI filesystem we ship with the devkits. Jonathan Cormier

FF 04:32 PM Software Development: RE: SocketCAN configuration

Thanks for the quick response. What version of busybox are you using?
Thanks,
Fred Fred Frantz

JC 03:24 PM Software Development: RE: SocketCAN configuration

I used the busybox ip utility to configure can when I last tested it.
I found the following script which I created to configure can.

See the following cantest script which is used to test can by connecting... Jonathan Cormier

FF 03:16 PM Software Development: SocketCAN configuration

What is the recommended method for configuring a socketCAN port on the MitySOM3354? I have tried using the iproute2 utility as described in the TI instructions.
