CN9132 COM startup error messages

Hi Solidrun support,

I bought a CN9132 COM module and mounted it on our based board with COM Express Type interface support.

I changed the BOOT MODE to SPI. So, the COM board starts up with a factory u-boot image and got below error messages,

Could you please help to resolve it and reach to ping ok via the ethernet interface of COMe connector?

I have contacted the CN9132 team to look at your errors logs. We will get back to you soon.

The errors have gone while loading the uboot flash-image.bin (generated from cn913x_build) via serial console today. It is likely the flash image came with the board has some problems.

Now, I want to load ubuntu image to on-board eMMC and change BOOTMODE to eMMC. Could you please tell me how to do it?



As I did not have CN9132 basebard,
Would you please share how to upgrade “cn9130-cex7_config_0_ubuntu-4cbe176.img.xz” to eMMC via u-boot tftp ?



The board failed to boot ubuntu image provided on Solidrun web site.

  1. download ubuntu-cn9132-cex7-mmc:1:0.img.xz
    $ wget\:1\:0.img.xz

  2. flash the image into a USB disk (/dev/sdb)
    $ xz -dc ubuntu-cn9132-cex7-mmc:1:0.img.xz | sudo dd of=/dev/sdb bs=4k conv=fdatasync status=progress

  3. insert the USB stick to the baseboard with CN9132 COM mounted and power on it.
    Likely, the Linux kernel could not mount root filesystem.

CN9132 boot log is as below URL, cn9132-boot-log-0911

The boot up stopped at line# 631 (Waiting for root device ) below,

If the rootfs is found and runs the init script, etc. and eventually enters ubuntu shell. This is the outcome I’d like to see it.

Could you please advise how to resolve it?

I flash the image file into a SATA storage and insert back the baseboard which has CN9132 mounted. It can boot into ubuntu shell. Something wrong in USB boot ?!

can you please post your boot log. Most likely the root args passed to the kernel are incorrect for a USB boot.
