Title: CAN bus with TE0803 + TEBF0808
Post by: joseer on January 16, 2020, 06:02:57 PM
Hello,

I'm trying to work with the CAN bus on these kit, which I routed through EMIO using the dedicated PL pins HDIO_SC18 and HDIO_SC19 but unfortunately when I boot petalinux I've got:

Code Select

Did you test/try the CAN bus with this kit in petalinux? any ideas what could it be wrong?

Thanks.

I ran the vivado "starterkit" reference project and I've got it working now, it was down to get the correct setup in the device tree can node.

Hi,
good to hear that it works now.

Short note: In case you change something on PS setup or PS-PL address space, always regenerate all files. Everything belongs together.
