Buildroot SD card Firefly image boot fails with: "failed to find part:boot&

Chip Platform Rockchip
1

Tested on Buildroot 2016.05 and master @ a26aa9686ad457d208df3b85a39c9befa04caaa3

Here’s the image for convenience: https://github.com/cirosantilli/media/blob/bc206d0c3aed5e85b4fd68346ce99db8b334c0ce/buildroot-firefly-sdcard-2016.05.img but it is just simply generated with the defconfig from buildroot.

Followed instructions under board/firefly/firefly-rk3288/readme.txt

Then from a TTL I see:

    arm pll = 600000000HZ
    periph pll = 300000000HZ
    ddr pll = 200000000HZ
    codec pll = 594000000HZ

The official Ubuntu image worked on my sdcard.

On buildroot’s bugtracker: https://bugs.busybox.net/show_bug.cgi?id=9226

Hi
Did you get the same problem with the cross compiling toolchain in the android sdk?

3

@Isle sorry for late reply, thought I would get an email.

Haven’t tried that. Buildroot builds it’s own cross compiler toochain.

If I get to it, I will post what happened.

I have managed to boot from TTL as follows:

  • enter recovery mode (hold recovery and restart board by resetting)

  • download upgrade tool, and official Ubuntu image, and run:

    sudo ./Linux_Upgrade_Tool_v1.2/upgrade_tool uf Firefly-RK3288_Ubuntu14.04_201607222032.img

    This burns the image to the eMMC.

  • that image works. From inside of it, clear eMMC to ensure that it will not be used instead of the SD: sudo dd if=/dev/zero of=/dev/mmblk0

  • try again

However I can’t get HDMI / VGA output to my screen, only TTL access.

I also tried to insert the cable after boot, but it did not help.

5

hi
what did you get from cmd:
ls /sys/class/display/

6

That directory does not exist.

I will also try to get my hands on a better power supply, currently using USB.

Here’s the image for convenience: https://github.com/cirosantilli/media/blob/bc206d0c3aed5e85b4fd68346ce99db8b334c0ce/buildroot-firefly-sdcard-2016.05.img but it is just simply generated with the defconfig from buildroot.

7

hi
your img seems strange。
you can extra the official img to see the difference

8

Sorry, what do you mean?

I don’t know much about board bringup, so I don’t know what to compare. If I did, I’d have patched buildroot already :slight_smile:

I highly recommend you patch buildroot to work, would be great for your ecosystem :slight_smile:

9

HI
your image from github :buildroot-firefly-sdcard-2016.05.img
how did you made it ?

10

@isle buildroot… https://github.com/buildroot/buildroot :slight_smile:

git checkout 2016.05
make firefly_rk3288_defconfig
make

Someone had made a config for it: https://github.com/buildroot/buildroot/blob/master/configs/firefly_rk3288_defconfig but maybe it is broken.

11

Hi
Yes ,I have tried ,and got the same informations.
I think,the u-boot couldn’t load the boot.
But I am unfamiliar with the buildroot program.
I will try to fix when I am free.

Hi
I have tested it again ,and the result is success.
the reason is load the wrong uboot ,we need clean up the spl and uboot from the EMMC FLASH
First of all flash a normal ubuntu firmware to the board ,then,boot the os.
clean the spl and uboot by

dd if=/dev/zero of=/dev/mmcblk0 bs=1M count=4

then reboot ,
now,insert your sdcard and power up .

switch to partitions #0, OK
