How to make a SD card with bootloader


(Ed) #21

Thank you! That worked to download u-boot.bin However, when I re-power the BPI-W2, it boots to OpenWRT on the board, not ubuntu on the SD card. Looking at the boot log, references to SD appear around the 10 second mark, which I’ve listed in full below, but specifically, at 13.439279 I see this:

[   13.439279] block: attempting to load /etc/config/fstab
[   13.445329] block: unable to load configuration (fstab: Entry not found)
[   13.452266] block: no usable configuration

Is this preventing the BPI-W2 from booting from the SD card? I have confirmed that there is no /etc/config directory on the SD card:

root@OpenWrt:/# lsblk

The LEDs of eth0 do not work in ubuntu now, it works under router mode.

We are waiting for permit to open schematic and kernel source, will soon.

Hi Jalen,

could you please check the power adapter, does it output 12v ? right ?

And please compare the uImage loaded from tftp and sd card by using below commands under u-boot:

  • tftp uImage
  • fload sd 0:1 1500000 uImage
  • cmp.b 0x1500000 0x3000000 0xc33168

please compare dtb file with the same way.

Hello,

in addition to the above startup problem, the logfiles Bananapi_w2.log (29,8 KB)

after about 1 minute power and reset at 62 ° C core temp Bananapi_w2.log_1 (75,8 KB)

greetings

Hello,

I use a 12V 2A power adapter which I bought with W2 board from the seller. The adapter also has a bpi logo.

I compared the file following the step. It says the same file.

Hi all,

please follow below steps to boot up from emmc and load linux from SD card.

  1. update u-boot(dvrboot.exe.bin) in emmc to latest version via MP_tool or hypertrm. (make sure the SW4 been switched to 0)
  2. run commands under u-boot to reset env vars:
    • env default -a
    • save
  3. plug in SD card and reset the board, it will boot up from eMMC and load linux from SD card.

I suspect that the SPI ROM from RTK is not stable now, if the board can boot up from eMMC normally, we will push RTK to update SPI rom.

Thank you, that worked! Now I eagerly await HDMI support. :slight_smile:


#28

When switch SW4 0 and reset env to default, I can boot to sd card right now. It looks no error for booting.

Thanks.
