Hi there,
I am trying to get an OLinuXino-A64 board with a SPI flash to work:
- U-Boot in the SPI flash, with TF-A, SPL and DTB - Linux in the SPI flash, loaded and run by U-Boot
I can build U-Boot with SPI_SUNXI_SPL just fine. It boots from the flash, and jumping to regular U-Boot works, too. However, the second U-Boot no longer recognizes the SPI bus. I figured out that there is a dedicated option `CONFIG_SPI_SUNXI`. Now when I activate that and try to build again, the linker is having trouble finding core device driver functions:
MKIMAGE u-boot-dtb.img COPY u-boot.bin CC spl/common/spl/spl.o CC spl/lib/display_options.o CC spl/drivers/spi/spi-sunxi.o AR spl/lib/built-in.o AR spl/common/spl/built-in.o AR spl/drivers/spi/built-in.o AR spl/drivers/built-in.o LD spl/u-boot-spl drivers/spi/spi-sunxi.o: In function `sun4i_spi_set_mode': /home/bob/build/racklet/olinuxino-a64/u-boot/drivers/spi/spi-sunxi.c:459: undefined reference to `dev_get_priv' drivers/spi/spi-sunxi.o: In function `sun4i_spi_set_cs': /home/bob/build/racklet/olinuxino-a64/u-boot/drivers/spi/spi-sunxi.c:167: undefined reference to `dev_get_priv' drivers/spi/spi-sunxi.o: In function `sun4i_spi_release_bus': /home/bob/build/racklet/olinuxino-a64/u-boot/drivers/spi/spi-sunxi.c:329: undefined reference to `dev_get_priv'
and so on.
I am using the U-Boot config and patch for SPI flash in DTS and defconfig in here: https://github.com/orangecms/arm-cpu/tree/main/olinuxino-a64
I'd be glad to get this to work; any hint is welcome. :)
Thanks and stay safe! Dan
