I’d like to add a “USB to SPI” IC “MCP2210” to extend my SPI ports in hardware,
And some others ICs’ deiver will controlled via MCP2210,
I’ll access a SPI eeprom through MCP2210 in eeprom’s driver.
Does anybody have experience on this?
Or Is there any example?
May I know which HW platform you’re using?
Jetson AGX Xavier?
Which JetPack SW version?
Your topic was posted in the wrong category. I am moving this to the Jetson AGX Xavier category for visibility.
You can use jetson-io to configure pins for SPI.
Ohers like driver device tree for MCP2210 may need figure it out by yourself.
First, thanks for your reply.
but jetson-io is for the physical ports that AGX Xavier has.
am i right?
The MCP2210 bridge is attached to a USB port and acts as an HID device,
I have no idea how to add a node for this.
Yes, jetson-io only configure the Xavier SPI.
Then, I would suggest to consult with vendor if any driver can provide or able enable it by kernel configure.
