This should be simple. I am building a ucLinux system using kmenuconfig. My hardware supports two SPI devices, one of which is already committed to flash memory. I have built a kernel with SPI enabled, and booted it, and run 'busybox mdev -s', and rebooted, and it finds a SPI device: spi_m2s spi_m2s.0: registered master spi0 spi spi0.0: setup mode 3, 8 bits/w, 41500000 Hz max --> 0 m25p80 spi0.0: s25fl129p1 (16384 Kbytes) Creating 3 MTD partitions on "s25fl129p1": 0x000000000000-0x000000010000 : "spi_flash_uboot_env" 0x000000010000-0x000000410000 : "spi_flash_linux_image" 0x000000410000-0x000001000000 : "spi_flash_jffs2" spi_m2s spi_m2s.0: registered child spi0.0 spi_m2s spi_m2s.0: SPI Controller 0 at 40001000,clk=83000000 I have a SPI-looking device in /sys/devices/platform: ~ # ls -la /sys/devices/platform/ drwxr-xr-x 9 root root 0 Jan 1 00:07 . drwxr-xr-x 5 root root 0 Jan 1 00:07 .. drwxr-xr-x 6 root root 0 Jan 1 00:07 m2s_eth.0 drwxr-xr-x 3 root root 0 Jan 1 00:07 musb_hdrc drwxr-xr-x 2 root root 0 Jan 1 00:07 nop_usb_xceiv drwxr-xr-x 2 root root 0 Jan 1 00:07 serial8250 drwxr-xr-x 3 root root 0 Jan 1 00:07 serial8250.0 drwxr-xr-x 3 root root 0 Jan 1 00:07 serial8250.1 drwxr-xr-x 4 root root 0 Jan 1 00:07 spi_m2s.0 -rw-r--r-- 1 root root 4096 Jan 1 00:07 uevent What I *want* are: /dev/spi0 /dev/spi1 Or suchlike. How do I get them? Enquiring minds want to know. Eric -- cc:NSA
