Porting u-boot on phytec phyboard mira

[shabbirbohra94]

phytec  imx6_all   #barebox‌ #u–boot‌

phyboard mira has barebox bootloader but I am trying to port u-boot instead of barebox.

Referring I.MX BSP PORTING GUIDE I made a custom u-boot image for this board and flashed this image to SD Card using dd command as follow: 

   sudo dd if=u-boot.imx of=/mmcblk0 bs=512 seek-2 skip=2 conv=fsync

Configured the switch to boot from SD card but could not sees anything on scree.

What Could be the reason ??

What other method can I try to load u-boot from Barebox?

I found out why I was not able to see the Boot log, it was due to incorrect serial console setting. I changed serial console to uart2 which was set to uart1 previously. Now I am able to see the u-boot log but however getting a PMIC error.

Hello Shabbir Bohra,

The Phyboard Mira is manufactured and supported by Phytec so they may be able to provide some assistance on their board.

That being said, if you are booting an i.MX6 based board you need to skip 1k so the command would look something like:

$ sudo dd if=u-boot.imx of=/dev/sdx bs=512 seek=2 conv=fsync

Also, make sure that the bootloader is set to boot from the SD card as it needs to be configured differently depending on from where it will boot.

I hope this helps!

Hello Sir,

The Board is Booting from SD card only, because I have tried flashing original Barebox image and it is working. The issue is only with the custom

u-boot image .

I also tried this command:    $ sudo dd if=u-boot.imx of=/dev/sdx bs=512 seek=2 conv=fsync

and the result is same.

Hello Shabbir Bohra,

I would recommend contacting Phytec, as they may be able to provide the correct uboot configuration for their board. It could be that the hardware description for the board is not correct or complete and that's why it cannot load correctly.
