Hello, I saw that here is also a mailing list dedicated to device model issues but it looks obsolete (last post February 2014) so I am using this forum.
I have a problem nearly identically to http://lists.denx.de/pipermail/u-boot/2015-April/210754.html
The SPI initialization does not work:
Invalid bus 0 (err=-19) *** Warning - spi_flash_probe() failed, using default environment
This is the device tree compiled into u-boot:
U-Boot> fdt addr 0x8FEB8A7C U-Boot> fdt print / { #address-cells = <0x00000001>; #size-cells = <0x00000001>; aliases { serial0 = "serial@40600000"; spi0 = "/axi_quad_spi@44a00000"; }; memory { device_type = "memory"; reg = <0x80000000 0x10000000>; }; axi_quad_spi@44a00000 { compatible = "xlnx,xps-spi-2.00.a"; reg = <0x44a00000 0x00010000>; spi-max-frequency = <0x423a35c7>; #address-cells = <0x00000001>; #size-cells = <0x00000000>; status = "okay"; is-dual = <0x00000000>; num-cs = <0x00000001>; flash@0 { compatible = "n25q128a11"; reg = <0x00000000>; spi-tx-bus-width = <0x00000001>; spi-rx-bus-width = <0x00000004>; spi-max-frequency = <0x0d3ed78e>; #address-cells = <0x00000001>; #size-cells = <0x00000001>; partition@qspi-fsbl-uboot { label = "qspi-fsbl-uboot"; reg = <0x00000000 0x00100000>; }; partition@qspi-linux { label = "qspi-linux"; reg = <0x00100000 0x00500000>; }; partition@qspi-device-tree { label = "qspi-device-tree"; reg = <0x00600000 0x00020000>; }; partition@qspi-rootfs { label = "qspi-rootfs"; reg = <0x00620000 0x005e0000>; }; partition@qspi-bitstream { label = "qspi-bitstream"; reg = <0x00c00000 0x00400000>; }; }; }; };
Has anybody an idea how to debug this further? Thanks, Marco
