I wanted to play with: kernel on ubifs or perhaps DAX on erofs. Btw, Amlogic's boy did "job secure". The bootloader must be signed with aml-enc, a x86 binary, differently for SD and NOR flash. Anyways, it makes x00kb of trice encrypted and signed 0s.

https://github.com/radxa-pkg/u-boot-aw2501 This is the radxa u-boot build. The important build scripts are in the Makefile.local and the ones in the main directory. I believe the patch directory is in the Debian folder. https://github.com/radxa-pkg/u-boot-aw2501/blob/main/.github/local/Makefile.local https://docs.radxa.com/en/cubie/a7a/low-level-dev/build-system/u-boot Use AI to help you figure it out. My armbian build downloads the official uboot deb package. But I also added a directory for custom uboot packages that overrides the official package.

How can we acces the SPI NOR Flash on Odroid HC4? The usual error seems to be the driver, not a thing we can overlay device tree? Id for xt25f128b is implemented. meson-spifc ffd14000.spi: registered host spi0 spi spi0.0: setup mode 0, 8 bits/w, 1000000 Hz max --> 0 spi-nor spi0.0: supply vcc not found, using dummy regulator spi-nor spi0.0: error -95 reading JEDEC ID spi-nor spi0.0: probe with driver spi-nor failed with error -95 meson-spifc ffd14000.spi: registered child spi0.0

Looks like I'm stupid. I can’t figure out which _defconfig is used to compile u-boot for cubie-A7A. I understand that 2022.07 is used as the source, but there is no necessary _defconfig in the configs folder. Accordingly, I don’t understand which file to write a patch for, or which patch to make changes to. I ask for help in writing the required patch.

In case you're interested I’ve uploaded my experiments with the current and edge kernels for my board (X88pro13, RK3528) to GitHub x88pro. LAN and USB are working; HDMI is not. Wifi only in current with aic8800 chip. Device Tree for my Board : userpatches/kernel/archive/rockchip64-.../dt/x88pro.dts might interest you.
