AM4379: AM4379

Hello,

In order to help you better, can you please post the query in English.

Regardsm

Prashant

We designed our OP50_Mainboard_AM437x board with reference to AM437X_INDUSTRIAL_EVM_3K0008_REV1_4A and AM437X_GP_EVM_3K0006_REV1_4A. sd card tisdk-default-image-am437x-evm.wic runs normally on the purchased development board. But there is no message output in our OP50_Mainboard_AM437x board debugging serial port. Does the tisdk-default-image-am437x-evm.wic tape need to be modified?

Thanks, tingshan.qin qin. I have assigned the query to our subject matter expert.

Yes typically the U-Boot and kernel should be modified and re-configured to work with the new board.

What I want to know is whether debugging information is output before ddr initialization. Because we changed the ddr chip, the ddr may not work properly. Without any debugging information output, there is no way to determine what the problem is

Thanks!
