Booting ROCK Pi 4(A/B/C) with mainline u-boot in SPI, NVMe and Armbian v20.11.x

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
