Set the SD card to start TWR-LS1021A, the serial port has no output information

[hfkjsaoidu213]

Hi,

  I am using LS1021A TWR board for development. But after read the pdf file Layerscape Software Development Kit User Guide(Supports: LSDK 20.04_290520), booting through SD card mode encountered the following problems.

1）Execute the following flex-installer command to automatically install LSDK default rootfs_lsdk2004_LS_arm64_main.tgz and bootpartition_LS_arm64_lts_4.19.tgz.

   flex-installer -i auto -m ls1021atwr -d /dev/sdb

Here is what the terminal looks like after executing this command.

2) Plug the SD card into the TWR-LS1021A board. Set the SD card to boot.

3)Then power on the board.

  But the serial port does not have any output information.

pls help me confirm above question, thank you very much.

The target board is Version 2.0

[yipingwang]

Would you please configure your target board booting from NOR flash, then provide u-boot console log?

Please check whether the block size of your SD card is 512bytes.

On your host PC, please deploy SD card with the following command(please note "bs" is the block size of your SD card), then plug in SD to your target board, after configuring the switch setting to check whether there is output information.

dd if=firmware_ls1021atwr_uboot_sdboot.img of=/dev/sdb bs=512 seek=8

[hfkjsaoidu213]

嗨,

     yipingwang,I used the IMG you provided, load it to the SD card under Linux using the dd command, and then power on the board.The serial port still has no output information.

• Attached file is the u-boot console log started from NOR Flash.

[yipingwang]

Would you please provide u-boot console log similar as the following?

There is no output information of u-boot. After about 2 minutes, kernel information is directly printed out.As the attached file.

[yipingwang]

Please type "reboot" under Linux Kernel prompt.

[hfkjsaoidu213]

There is no command input line, so cannot type "reboot".

[yipingwang]

When did you purchase this TWR-LS1021A? The CPU on the target board is Version 2.0 or 1.0?

[hfkjsaoidu213]

Hi，

yipingwang，The target board is Version V1.0, 1.0GHz.

What is the difference between 1.0 and 2.0? Is it the supported SDK that is different?

[yipingwang]

The LSDK is only used for LS1021A 2.0 platform. For  LS1021A 1.0, you could use QorIQ SDK 1.8 release.
