PROCESSOR-SDK-AM62X: Assistance Needed with Enabling spidev on AM62x Processor

Part Number: PROCESSOR-SDK-AM62X

Tool/software:

Hi, Good Afternoon!

I am working on the AM62x processor and have shared the output and the code for enabling spidev using the overlay method. However, it is still not appearing in /dev when running the ls command.

Could you please help me understand what might be the issue?

Additionally, should I make any further modifications to the DTS file to enable spidev properly? Your assistance in resolving this would be greatly appreciated.

Thank you!

Best regards,

Vaishnavi
