AM62A7: Build an SD card using create sdcard.sh, but the serial port does not print logs

Hello,

You can follow one of the methods from the following link to create SD card:
https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/09_02_01_09/exports/docs/linux/Overview/Processor_SDK_Linux_create_SD_card.html

Hello,

Yes, I built the SD card using the create sdcard. sh method in the link, but the serial port does not print logs.

Regards,

Daohong

The log of./create sdcard.sh is as follows.

################################################################################

This script will create a bootable SD card from custom or pre-built binaries.

The script must be run with root permissions and from the bin directory of
the SDK

Example:
 $ sudo ./create-sdcard.sh

Formatting can be skipped if the SD card is already formatted and
partitioned properly.

Would you like to re-partition the drive anyways [y/n] : y

 
Now partitioning sdc ...


################################################################################

	Select 2 partitions if only need boot and rootfs (most users).
	Select 3 partitions if need SDK & other content on SD card.  This is
        usually used by device manufacturers with access to partition tarballs.

	****WARNING**** continuing will erase all data on sdc
