LS1043A-SDK Image sdcard boot hangs at Kernel start

[tmorrison]

I have built with flex-builder a firmware image and loaded it onto a sd card

I have put that into my board and U-boot comes up, and I do the following:

    mmc read a0000000  8000 14000

    bootm a0000000#ls1043argw

This is the result:

   bootargs=console=ttyS0,115200 root=/dev/ram0
   MMC read: dev # 0, block # 32768, count 81920 ... 81920 blocks read: OK

I know I got past this once, but I need to get past this again...

Hello Thomas Morrison,

Which version LSDK are you using? The latest release LSDK 19.09 or  20.04 doesn't support ls1043argw.

Would you please provide your patches applied on  flex-builder LSDK to support ls1043argw?

I uploaded lsdk2004_yocto_tiny_LS_arm64.itb in the following link.

https://drive.google.com/open?id=1Awquuv3lKTc-qAdSFg22C7rkgIPXWWPK 

Please deploy it on your SD card and check whether you could execute the following command to start Linux Kernel.

 mmc read a0000000  8000 14000

bootm a0000000#ls1043ardb

Thanks,

Yiping

Hi Yiping,

Thank you for getting back to me so quickly.

We are working with 18.03 (with patches for RGW). I know it's old and

decrepit

but we are only using it for the uboot (which I am trying to port "up" to

modern

OpenWrt)

thank you

tom

I tested first by tftp'ing this image over and trying to boot from it - it crashed

(we don't have a NOR flash that it is trying to accessing):

Would you please provide patches for RGW based on LSDK 18.03?

Would you please provide the procedure which you used to generate the itb image?
