btrfs on Helios4 is now on by default and there is a uboot-btrfs extension to easily enable this for other boards or even at compile time.

With the latest changes in Armbian and most importantly the update of u-boot to v2025.10 for Helios4, it is now possible to boot SATA and USB from u-boot flashed to SPI NOR flash, with the dip switch set to SPI boot mode. This even includes booting straight from u-boot to btrfs now.

Yes, give me a couple days as I am in the middle of project.

Hello, I have the same issue. UART output: Trying a 2023 build to see if it starts, but looking online it looks like this is caused by a kernel build being incomplete and when it's wrong the device specific kernel files are smaller than usual. I noticed the 2023 image is about double the size. Same error on that, though channel 0 CS = 0 MR0=0x98 MR4=0x3 MR5=0xFF MR8=0x8 MR12=0x72 MR14=0x72 MR18=0x0 MR19=0xS = 1 MR0=0x18 MR4=0x3 MR5=0xFF MR8=0x8 MR12=0x72 MR14=0x72 MR18=0x0 MR19=0x0 R0=0x988 MR4=0x1 MR5=0xFF MR8=nel 1 training pass! change freng done channel 0, cs 1, advanced training done ng done ng done change freq to 856MHz 1ng done ng done ng done ng done ddr_set_rate to 416MHZ,Boot1 Release Time: May 29 2020 17:36:36, version: 1.26 CPUId =mmc: ERROR: SDHCI ERR:cmd:0x102,stat:0x18000 mmc: ERROR: Card dOR: SDHCI ERR:cmd:0x102,stat:0x1mmc: ERROR: SDHCI ERR:cmd:0x102,stat:0x18000 mmc: ERROR: Card did not respond to voltage select!
