Uboot Package Source Files for Debos-Radxa

Can someone point me to the source code for the uboot package used in the current debos-radxa builds?

Particularly I am looking for the source to radxa-cm3-io-rk-ubootimg_2017.09-gcd33ad2313-211223_all.deb found here: https://github.com/radxa/debos-radxa/tree/main/rootfs/packages/arm64/u-boot

I have seen and used the source code at https://github.com/radxa/u-boot but it seems that this code is not what the debos-radxa package is built on. The uboot console shows 2017-09-gcd33ad2313 and is the name of the package, but I can not find this in the repository.

U-Boot SPL board init
U-Boot SPL 2017.09-gcd33ad2313-211223 #stephen (Oct 19 2022 - 10:29:20)

The only uboot branch that has the radxa-cm3-io-rk3566_defconfig in uboot/configs is the stable-4.19-rock3 branch. I have built uboot from this and confirmed it does not work with the latest debos build

Reason being, I am trying to disable the uboot console output on UART2. I am using the CM3 as a “drop in” replacement for the rpicm4 and this is a design requirement. I have switched off the debug output on UART2 using the config.txt, but I still get uboot console before the kernel boot.

If source code cannot be shared, can there be a image version without uboot console output on UART2? Or just the u-boot.itb and idbloader.img that I can write into the partitions of the latest image?


This is the source code.

To disable U-Boot log, changing u-boot source is needed. Please try to add the following patch.

diff --git a/configs/radxa-cm3-io-rk3566_defconfig b/configs/radxa-cm3-io-rk3566_defconfig
index 74e4db6d754..00855c29b08 100644
--- a/configs/radxa-cm3-io-rk3566_defconfig
+++ b/configs/radxa-cm3-io-rk3566_defconfig

Thanks Stephen, for pointing me to the commit hash and the tip to disable the u-boot log.

In the process of testing again, I found my underlying issue which was that my build machine was missing python2 which prevented a successful u-boot itb. I was following the directions here: https://wiki.radxa.com/Rock3/dev/Debian

which shows the required build tools includes “python” and I did not realize I needed python2.

This may be useful to someone else trying to build u-boot, until the wiki page is updated

also, I added CONFIG_DISABLE_CONSOLE=y which did stop some of the console output. Here is what I am still getting. At least I can build u-boot now and make adjustments as needed. Thanks again
