LS1043a SD card boot failed

Hello all:

As title, it's a simple questions, I bought a LS1043a EV board (Yes, that orange case one), but I don't know why I always cannot boot from SD card, I already change the DIP switch to SD boot mode, but I still cannot see anything on debug console, somebody could give me a simple instructions how to boot up from SD card? Thank you so much!

U-boot and Kernel use mainline source code, Debian rootfs, thanks.

Maybe it is u-boot defconfig issue?? I use sdcard_defconfig without secure function.

Thank you

Please try to prepare bootable SD card using attached U-Boot image from the SDK v2.0-1703 pre-built images ISO:

Form Linux Host PC

Insert SD card into Host.

Use the "dd" command

# dd if=u-boot-sdcard-2016.09+fslgit-r0.bin of=/dev/sdb  seek=8 bs=512

From ls1043ardb doard

Insert SD card into target board and power on.

Programming U-boot image to SD Card

=> tftpboot 82000000 u-boot-with-spl-pbl.bin  => mmc write 82000000 8 800 => cpld reset sd

Thank you, but I'm confuse, the u-boot image is already in SD card, why I need to programming again?

and as you said, the 2 part "Programming U-boot image to SD Card" is boot from nor flash and issue the command to flash u-boot to SD card, right?

It cause my 2nd questions, if I making board by myself in the future, the original nor flash is empty, how to flash SD card first time??

Anyway, thanks for your answer.

Please explain how you prepared the SD card which is not bootable.

Hello ufedor:

Step 1.
Compile u-boot ( I adapted GitHub - qoriq-open-source/u-boot and choose ls1043ardb_sdcard_defconfig as default configuration).

Step 2.

Bott EV board from NOR flash, and use your comments as above, flash u-boot-with-spl-pbl.bin to cpld on u-boot, and flash u-boot.bin to my uSD card.

Step 3.

Change SW4 configuration and SW5 configuration 1st bit)： 0_0010_0101 -> 0_0100_0000 to SD boot mode, then insert my SD card on to the EV board.

Step 4. Re-plug the power adapter and no any response from debug console

What's wrong with my steps, thanks.

> Bott EV board from NOR flash, and use your comments as above, flash u-boot-with-spl-pbl.bin to cpld on u-boot, and flash u-boot.bin to my uSD card.

Make sure you use the right binary.

u-boot-with-spl-pbl.bin is the one to write to the SD card, not u-boot.bin

You can also write to the SD from a PC, using dd:

sudo dd if=u-boot-with-spl-pbl.bin of=/dev/sdc bs=512 seek=8

Note that you also need to write the FMan and/or QE firmware, the location of this on the SDcard can differ based on your u-boot version

Hello Mathew

Thank you for your reply, this is my first time to touch HPC board, so I still confuse about your comment, as my understand, my steps have to changing as below:

Step 1.

sudo dd if=u-boot-with-spl-pbl.bin of=/dev/sdc bs=512 seek=8

Step 2.

Change SW4 configuration and SW5 configuration 1st bit)： 0_0010_0101 -> 0_0100_0000 to SD boot mode, then insert my SD card on to the EV board.

Step 3.
Plug-in power cable and boot up.

Seems easy, right? I will test later, but I don't know what is FMan and/or QE firmware? Is it necessary? Or just flash u-boot-with-spl-pbl.bin is enough? I need research 2nd stage (kernel image) when I done this.

Thank you for your support
