DRA821U: early booting to connect Ethernet immediately

Sung-IL

Part Number: DRA821U

Dear Champs,

My customer would like to connect Ethernet(CPSW5G) immediately after booing, and they need to receive Ethernet communication packets.

I got the response that this feature will be implemented on SDKv8.4 in below e2e,

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1121859/dra821u-early-booting-to-connect-ethernet-immediately/4160907#4160907

But, it seems this feature is not implemented on SDK8.4. Could you please let me know if this feature is included in SDKv8.4?

When I checked the UG of SDK8.4, I could not find any difference between SDKv8.3 and v8.4.

Thanks and Best Regards,

SI.

Remote-proc doesn't require any changes for enabling ethernet from u-boot. The way I mentioned in the attached thread is to use the native linux driver for ethernet (same which is used for cpsw2g) and not Ethfw which requires remoteproc. Let me know if there is any specific requirements for using Ethfw from u-boot.

For the changes required for this, you can refer to this thread.

Tanmay
