AM5726: Debug messages in MLO

rekoe

Part Number: AM5726

Hello,

How can I generate debug output within the MLO?
So far I have activated the "Low-level debugging functions" and specified the address of the UART3 0x48020000.

Unfortunately this is not enough to generate messages via printf or printascii.

best regards

Hello,

I am wondering if it would be possible to connect your board to CCS. Usually, while debugging MLO, I boot the board using a SD card/other boot media. Then, I connect to CCS without any gel files and load the symbol "u-boot-spl". It enables me to step through the MLO code without any problems and it is easier to debug than the printf statement.

Hello,

I don`t use the CCS environment. I have only "u-boot", crosscompiler and a SD-CARD.

and now i want to see that the MLO is executed correctly in the processor. furthermore i want to do a small memory test after the SDRAM initialization and there output over the UART is very helpful.

Best Regards

Hello,

If you are debugging a certain file, please add "#define DEBUG" on the top of the file.
