Flash eMMC on LS1046ARDB

Chanh — Sun, 15 May 2022 03:37:44 GMT

Hi all,

I want to flash the eMMC on LS1046ARDB. I only found some guide on flashing using TFTP (need an ethernet connection, which is not suitable for me).

May I know any other method to flash eMMC without ethernet (e.g. using USB interface)?

Thanks.

Hi Srinivasaraochi,

For the step:

"Write this image to QSPI Flash."

If I refer to the LSDK User guide section "4.1.5.3 Program LSDK composite firmware image", I can download either by TFTP server (which I am not able to do so due to ethernet), or download to mass storage, but how I could connect the emmc as a mass storage?

Thanks.

You could use the following command to load firmware image to memory.

=> ext2load usb 0:2 0xa0000000 firmware_ls1046ardb_emmcboot.img

Hi Yiping,

For the command you mentioned, is it the method that I need to copy the firmware to an USB, then connect the USB to the board?

Thanks.

Yes, you need to copy the firmware to an USB partition.

Hi Yiping,

I copy the image to an USB and connect it to the board, but when I use ls command to list the bin file, I cannot see any file there. before that, the usb info seems report error:

There is no Mass Storage USB mass storage device detected, this is abnormal.

Please try other USB mass storage device on the target board.

Please use u-boot from the formal released LSDK.

@yipingwang

I have visited the customer place and verified with other mass storage and its working fine.

Thanks Yiping and Srini for your support, with another USB device it works now.
