- Hello,
One of my MityDSP board is L138-FX-225-RC, which mean it has no FPGA. Can I used LCD display on this board?
because as far I search in this forum, we need FPGA to configure the LCD.
Also, please refer me to the step-by-step i... - DV 03:27 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: Altera spi
- Brian,
Would you mind posting your updated spi_test.c? I'll see if I can recreate what you're seeing on my dev kit.
Thanks,

This cleared up the errors on the DTB. I have tried to run the spi_test.c provided in a different post and still get the Unable to handle kernel NULL pointer dereference at virtual address 00000000.

The patch looks very useful. I need to set the mcp2515 as a module with menuconfig, correct? But I don't see that .ko being generated when I run make for the modules.

Looks like you don't have internet in the VM. When you started the VM did it ask you about specifying your computers network adapter.
