MicroZed SD Card boot problem

Hello all,

I am trying to build custom Linux for MicroZed 7010 by using Petalinux 2018.3. I would like to boot it from sd card. I have installed Petalinux and I have only changed INITRAMFS mode to SD card mode from "petalinux-config" . Than I have compiled the system without any error. My sd card is SDHC 16GB class 10. I have formatted it with two partitions as vfat and ext4. After compilation process has done, I copied to BOOT.BIN and image.ub file to first partition. For rootfs, I used the command like "sudo dd if=rootfs.ext4 of=/dev/sdb2 conv=fsync bs=1M".

I got below message and booting process has stopped before root login.

"bootconsole [earlycon] disabled"

In u-boot, I have changed the bootargs as

"earlycon console=ttyPS1,115200"

After that, I got lastly this message and I couldn't get into root login.

"Starting tcf-agent: OK"

I have set the boot jumpers correctly. How can I solve this problem?

Thanks inadvanced.

Hi,

Just to confirm using one of our pre-built images are you able to boot your MicroZed?
Verifying this would validate your jumper settings and the quality of your SD Card. Leaving the only variable to look into being your custom image.

Also when you built your image were you starting from one of our petalinux BSPs?

Thx,
Josh

Hello, I have still same problem. I got Dropbear ssh key, before "Starting tcf-agent:OK" message. Probably the rootfs is mounting to system but could not see the root login. Should I add some serial configurations to device tree or does it can be solve by setting the bootargs from u-boot? Is there anyone to have similar issue like this?
Thanks.

If you are using the Avnet posted BSP's pre-built image, you shouldn't have to make any modifications. The pre-built images were tested prior to posting. Reading back through, I see you formatted the first partition as vfat. I'm not sure what specific settings you used, but the recommendation is to use FAT32, like this:
$ mkfs.vfat -F 32 -n boot /dev/sdc1
