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
