Part Number: AM2434

Is CPSW3G or PCIe communication possible using the AM243x Cortex-M4?

Hi Sasaki-san,

Yes, both of these IPs are supported by AM243x SOC. Currently, we have only CPSW3G supported in driver.

PCIE will be supported in next version of SDK release (Feb-2022).

Prasad

Hi Prasad-san,

Thank you for the information.

I have confirmed the following documentation. Where can I find the Cortex-M4 Ether Driver in this document?

Also, the SDK sample project was only found for the Cortex-R5 core.

Best regards,
Sasaki

Hi Prasad-san,

Thank you. I checked TRM.

Cortex-M4 does not seem to be able to access CPSW, is it possible?

Hi Sasaki-san,

Even though it might be technically feasible to access CPSW from M4, it's not supported in our offering as access latency is very high.

We don't support and don't have plan for M4 CPSW driver either.
