Hi Ishan,

I have assigned the query to our expert, in the meantime, please look into these threads and see if it can be of any help.

Hi Ishan,

the first link Suren pointed to has much of the needed info, however we need different custom clk-data.c and dev-data.c files to support a clock ID of 153 (needed for main_uart2) instead of 155 (associated with main_uart4). I'm working on getting those files generated, and will circle back here soon.

Regards, Andreas

Thanks, Andreas. Looking forward to getting the required clk and dev files as we need to resolve this ASAP for our custom board.

Thanks,

Anil Patel

Hi Anil,

I'm still waiting for the files; just send a reminder to the developer. There's also a way to update the clk-data.c and dev-data.c files manually to add a new device ID and all related definitions (I've done it before) but it is rather painful and error-prone, not something you want to debug while also trying to bring up a custom board. I know we have a way to generate those in a scripted-fashion, which will be the better approach.

Will keep you posted.

Regards, Andreas

Thanks, Andreas.

I totally rely on your provided clk and dev files as they should be error-free. Looking forward to get that soon.

Anil

Hi Anil,

Andreas is out of office today. Please expect delayed response.

Hello Andreas/ Bin Liu

Is there any update on this?

We are waiting for the files. Pls run the script at your end and provide that.

Regards,

Anil

Hi Anil,

I since got a hold of the script; will start trying to get this configured and running here very soon.

Regards, Andreas

Hi Anil,

just a quick update; I have the script running but U-Boot SPL isn't working yet the way it should so I'm actively debugging this atm. Will be in touch.

Regards, Andreas

Thanks Andreas. Please Let me know when u have those files working correctly.

Regards,

Anil

Thanks, Andreas.

With your given files, I am able to get uboot logs on the desired UART (main_uart2)

Awesome, glad to hear! Let's close this thread then.
