Hi there,

 

Intel N3350

gpio_mem_NORTHWEST Registers:

 

for example,

 

Pad Configuration DW0 (PAD_CFG_DW0_GPIO_74)—Offset 610h

How can I retrieve the real physical address of "DW0 register"? 

 

Thanks a lot!

 

Jason

Hello @developer_iot,

 

Thank you for contacting Intel Embedded Community.

 

You may try D0+PORT_ID+offset(in this case 0610 for GPIO_74).

 

Best regards,
