LS1046ARDB Unable to boot from SD card

pholden — Fri, 09 May 2025 20:51:34 GMT

I am unable to boot from SD card. I have tried to use the "flex-installer -i auto -m ls1046ardb -d /dev/sdc" and have tried "flex-installer -b boot_LS_arm64_lts_5.10.tgz -r rootfs_lsdk2108_ubuntu_main_arm64.tgz -f firmware_ls1046ardb_sdboot.img -d /dev/sdc" from my build/images directory. They both end in a kernel panic (below). Any suggestions?

Hello,

Are you able to boot from the emmc nor flash? If the board is configured with the default switch settings and power is supplied to the board, then the boot loader (U-Boot) image
located in QSPI NOR flash virtual bank 0 runs.

After confirming it boots please review again your switch configuration and try again using the pre-build images.

Of course it booted with the default settings. I then switched the boot config switches to allow for sd-boot (as defined in the LS1046ARDB user guide), and this is what I got with both my slightly modified image AND the pre-built image.

@pholden
I've seen the same error when I was playing with LS1046AFRWY.
Look at this line:

[ 3.092365] Please append a correct "root=" boot option; here are the available partitions:

It seems that you didn't specify the `root=` option in u-boot env variable `bootargs`.
In my case it was

bootargs "root=/dev/ram0 rw console=ttyS0,115200 earlycon=uart8250,mmio,0x21c0500 ramdisk_size=0x10000000"

but then I forgot to upload the ramdisk via TFTP, and run "boot" command.

The same kernel panic is possible when you point wrong partition number of mmc in "root=" option.

This is what my bootargs looks like:

bootargs=console=ttyS0,115200 root=/dev/ram0 earlycon=uart8250,mmio,0x21c0500 mtdparts=1550000.spi-0:1m(rcw),15m(u-boot),48m(kernel.itb);7e800000.flash:16m(nand_uboot),48m(nand_kernel),448m(nand_free)

What should it look like for sdcard? Do I just change root to mmcblk0p1? I'm not about the rest. It doesn't look right either for SD card boot.

Did you download the flex-installer tool following the LSDK2108UG? , please try to flash only the firmware and test the image, also try with a diferent SD card and share screenshots of the process you followed.
