Hello,
I have a self build u-boot-with-spl.bin, which works when I put it onto an SD card and boot from that SD card (see also here BeagleV-Ahead automatic SD card boot ). I now want to try to flash that onto the eMMC. I therefore did the steps from the documentation (see here Quick Start — BeagleBoard Documentation ):
I got fastboot by android-sdk-platform-tools
I setup the udev rules
I downloaded the xuantie-ubuntu-23.04-20230705.zip (see here BeagleV-Ahead Ubuntu 2023-07-05 - BeagleBoard )
I upacked it and had a look into the fastboot_emmc.sh script
I then tried to do the steps, escpecially fastboot flash uboot ./u-boot-with-spl.bin using my own u-boot-with-spl.bin
The output then looks like this:
Sending 'uboot' (941 KB) OKAY [ 0.250s]
Writing 'uboot' OKAY [ 0.002s]
Finished. Total time: 0.257s
However, when powercycling the board, it boots the old, preexisting u-boot again! I can confirm that because in the uart output, I see the build date “10 June” instead of todays date!
What am I doing wrong?
Hi @Kilian , i’d fully expect:
fastboot flash ram ./u-boot-with-spl.bin
fastboot reboot
sleep 10
fastboot oem format
fastboot flash uboot ./u-boot-with-spl.bin
fastboot reboot
To correctly update the u-boot on the eMMC partition…
Regards,
Kilian

Unfortunately I don’t get it working: Whenever I execute the step fastboot oem format I get the message < waiting for any device > and then nothing more happens. I tried to flash ram my selfcompiled u-boot-with-spl.bin as well as the u-boot-with-spl provided in the zip. I also tried to hold down the USB button while executing fastboot reboot, but it didn’t help either. Any idea how I could debug this?
Best regards,
Are you scripting it, or running one at time?
First, hold down USB, and hit reset… so your in bootloader mode:

Wow, thanks! When running all commands from a script, it does work indeed. But why does it not work when issuing the commands manually?
Sorry, just something i also noticed, glad it fixed it for you…
This is really the first board I’ve utilized that used fastboot…
Regards,
me too! about the fastboot, me too!
