AM2632: Is there a limit to the number of peripherals?

Hi,

Please see the AM2632 datasheet, Table 5-1, Device Comparison for details on differences between AM2632 and other AM263x SOCs:

Hi,

Thank you for your reply.

Is there a reationship between Interconnect and number of COREs? 

PERI VBUSP Interconnect has R5 CORE and GPIO tables.

If we are using a 2-CORE product, are the only GPIOs available are GPIO0 and GPIO1?

Thanks & Regards

Hi,

For AM2632, only the GPIO1 and GPIO3 HW modules are available.

For AM2631, only the GPIO1 HW module is available.

However:

• Each R5F core has access to all GPI signals.
• Each GPO signal can be assigned to a specific R5FSS core by configuring the MSS_IOMUX.PAD_CFG_REG.GPIO_SEL[17:16] of the associated IOMUX Pad Configuration register.

Please see the AM263x TRM Rev C, 13.1.1.3 GPIO Integration.

Hello,

I would also like to know processor information for single/dual configuration.

From your description I interpreted that the processor is configured as follows:

For AM2631, R5FSS0-CORE1 is available.
For AM2632, R5FSS0-CORE1 and R5FSS1-CORE1 are available.
(Lockstep mode not supported ?)

Is this correct?

Thanks & Regards

Hi,

Sorry, I used incorrect indexing on GPIO modules before.

For AM2632, GPIO0 and GPIO2 are available.

For AM2631, GPIO0 is available.

Please see the AM263x TRM Rev C, Table 13-1:

            R5FSS0-0 = GPIO0
            R5FSS0-1 = GPIO1
            R5FSS1-0 = GPIO2
            R5FSS1-1 = GPIO3

For AM2632: R5FSS0-0 and R5FSS1-0 are available.

For AM2631: R5FSS0-0 is available.

Frank
