iMX7D RDC

rolfcrapp — Tue, 13 Feb 2018 09:40:12 GMT

With the RDC it's possible to assign ressources to the different cores.

Is it possible to assigne interfaces which are on the same gpio bank to different cores?

example:

GPIO4 bank:

- I2C1 to M4 core

- I2C2 to A7 core

- ECSPI1 to A7 Core

- ECSPI2 to M4 core

all this interface are on the same GPIO bank. But assigned to different cores.

in my understanding, the interface can be assigned as you like, regardless of which gpio bank they are.

only when allocating the GPIO, one full bank (ex. GPIO4 Bank) at a time must be allocated. However, regardless of the interface.

Hi rolfcrapp

you are right, the interface can be assigned as you like,

regardless of which gpio bank they are.

您好！

请问每个GPIO引脚都可以单独分配给不同的核心吗？还是说在作为GPIO时，只能将gpiox bank整组分配？
