Hi. I have soldered a Spansion FL064LIF01 SPI flash on my ROCK PI 4 SE and it is not recognised by debug console:

Loading Environment from SPIFlash... jedec_spi_nor flash@0: unrecognized JEDEC id bytes: 01, 60, 17
*** Warning - spi_flash_probe_bus_cs() failed, using default environment

The wierd thing is that "lsblk" detect it:

I have connected an ASM1166 SATA controller to m.2 slot and installing armbian to boot from SD and have root on SATA works fine, but fails if install to boot from MTD and have root on SATA. Is there any way to include ASM1166 driver in u-boot to be able to boot the board using MTD+ SATA ASM1166  adapter? 

Is it possible to make u-boot to cycle from eMMC->SPI->SD->USB->NVME->PXE like in RPi5 for example?

Thanks

That is because it is the linux kernel that is driving you own/custom SPI-flash chip. When you power on the board, it follows a certain priority of devices, see schematics of the board. It might be that SPI-flash is not included. And if included, the U-Boot you put in there might assume different wiring or none at all. It is can be because the U-Boot config it is compiled from does not include the right options. So create a custom U-Boot for your custom board.

 

I don't have a custom board. I have a ROCK PI 4 SE. These boards do not come with SPI flash IC soldered on the board, but have space if one chooses to solder SPI flash himself. Since I couldn't find flash IC that Raxda recommends: https://wiki.radxa.com/Rockpi4/hardware/spi_flash (W25Q64FV; GD25Q127CSIG;XT25F32B;XT25F128B) I found equivalent to W25Q64FV. The vendor Id of FL064LIF01 is different so I'm guessing that is why it is not recognized. I read that Piter75 had support for XTX flashes at first so other flash ICs can be added maybe?

This is exactly what my goal is but since I'm new to this I though posting on forum and ask for some help would not hurt.

Thanks

The foreign added SPI-flash makes it custom in terms of Armbian bootloader.

Look how to build U-Boot from Armbian build environment (development basically) or find howto on denx.de. It been a while since I last did that myself, so things might have changed a bit.

Well its equivalent so other than vendor not beeing in a database does not count as custom in my books, but that is beside the point. Armbian correctly recognizes the size and I can write to it and that is important.

Now flashing an existing image is simple. My preferred way is dd as described by Piter75:

dd if=uboot.img of=/dev/mtdblock0 bs=4K for u-boot images

and

dd if=idbloader.img of=/dev/mtdblock0 seek=64 bs=512 conv=sync

dd if=u-boot.itb of=/dev/mtdblock0 seek=16384 bs=512 conv=sync

if used with image tree blob. Nice thing is that if new u-boot hangs or does not boot I can just short pin 23-25 to boot from SD card and try again. Since I have an 8Mb flash I would really like to bake in m.2 to SATA drivers - for ASM1166 in my case. Any pointers are welcome.

Hi, Piter
Where do I download this file now?

I’m using the bootloader rk3399_loader_spinor_v1.20.126.bin because I have a ROCK PI 4A+ with board version 1.74.

rk3399_loader_spinor_v1.20.126.bin

The SPI bootloader only works with a RADXA U‑BOOT — any version based on 2017.09.img. I want to upgrade to a newer, working U‑Boot for SPI booting.

rockpi4a-uboot-trust-spi_2017.09.img.xz

 

The latest Armbian image that works and boots from an SD card is Armbian 23.02.2 Rockpi‑4a current, with Kernel: Linux 5.15.93. Later images won’t boot from the SD card, even if I short pins 23 and 25.

At the same time, upgrading Armbian 23.02.2 to the current Armbian 26.08.X (Kernel: Linux 6.18.X) works fine, and the board boots successfully.

 

I found the latest U-boot for the ROCK PI 4, as well as for other boards, on GitHub. Here is the link and the actual U-boot archive.
inindev / uboot-rockchip
rk3399-rock-pi-4.zip

All current ARMBIAN (26.08) images for Rock PI 4A start up with the new U-boot v2026.04
