- 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... - JC 01:44 PM Software Development: RE: How to load Linux Kernel and files system with no Ethernet port

You shouldn't need Promiscuous mode. This mode is usually used to packet sniff a network. It tells your network card to not filter packets destined to other computers.

- JC 03:13 PM Software Development: RE: DSP Quick start - with Linux OS

Now, connecting a USB-CAN PC logger I see multiple messages in the log, very closely spaced for each one sent by cansend on the l138.

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.
