# # Generic kernel configuration for PIC32 processor. # # This file contains all the devices and all the options available # for the pic32 platform. It's not expected to be buildable, as some # devices and options are mutually exclusive or incompatible. # It's intended to be used as a reference or as a starting point # when creating configuration for a new board. # # For details, see http://retrobsd.org/wiki/doku.php/doc/kconfig # architecture "pic32" cpu "PIC32MX7" # Processor variant board "CHIPKIT_MAX32" # Board type # Linker script ldscript "max32/bootloader.ld" # Need to set locally timezone 8 dst maxusers 2 # Standard system options options "HZ=100" # Rate of clock interrupt options "CPU_KHZ=80000" # Oscillator frequency of CPU core options "BUS_KHZ=80000" # Frequency of peripheral bus options "BUS_DIV=1" # Bus clock divisor 1/2/4/8 options "EXEC_AOUT" # Run a.out binaries options "EXEC_ELF" # Run ELF binaries options "EXEC_SCRIPT" # Run shell scripts options "UCB_METER" # Collect kernel statistics options "NPROC=10" # Number of processes, default 10 options "NBUF=10" # Number of i/o buffers, default 10 options "NFILE=24" # Number of files, default 24 options "NINODE=24" # Number of i-nodes, default 24 options "NMOUNT=2" # Number of mounted filesystems, default 2 options "SMAPSIZ=NPROC" # Size of swap map, default NPROC options "HALTREBOOT" # Reboot the processor on halt() options "KERNEL_HIGHLIGHT" # Highlight kernel messages # LEDs signal "LED_DISK" pin RF0 invert # disk activity indicator signal "LED_SWAP" pin RA1 invert # swap activity indicator signal "LED_TTY" pin RA2 invert # tty activity indicator signal "LED_KERNEL" pin RA3 invert # kernel activity indicator # Root filesystem at /dev/sd0a, swap at /dev/sd0b config unix root on sd0a swap on sd0b dumps on sd0b # Serial UART ports device uart1 # Serial-to-USB converter device uart2 device uart3 device uart4 options "UART_BAUD=115200" # default speed signal "UART4_ENA" pin RB13 # power enable signal # USB UART ports device uartusb # USB device mode, CDC function options "UARTUSB_BAUD=115200" # default speed options "USB_AUTOBOOT=YES" # don't wait for on boot options "USB_MAX_EP_NUMBER=3" # parameters of USB device... options "USB_NUM_STRING_DESCRIPTORS=3" # ...specific for CDC function # Console options options "CONS_MAJOR=UART_MAJOR" # use UART device as console options "CONS_MINOR=0" # uart1 is /dev/tty0 # SPI ports controller spi2 # SD card # microSD card device sd0 at spi2 pin RC14 # select pin options "SD_MHZ=10" # speed 10 MHz signal "SD0_ENA" pin RA5 # SD card enable signal # General purpose I/O ports # Flags define a mask of available pins # For 64-pin devices: device gpio1 flags 0xffff # port B device gpio2 flags 0xf000 # port C device gpio3 flags 0x0fff # port D device gpio4 flags 0x00ff # port E device gpio5 flags 0x003b # port F device gpio6 flags 0x03cc # port G # For 100-pin devices: device gpio0 flags 0xc6ff # port A device gpio1 flags 0xffff # port B device gpio2 flags 0xf01e # port C device gpio3 flags 0xffff # port D device gpio4 flags 0x03ff # port E device gpio5 flags 0x313f # port F device gpio6 flags 0xf3cf # port G signal "GPIO_CLEAR" pin RA5 # clear on startup # ADC driver device adc # PWM driver device pwm # GLCD driver device glcd # HX8357 driver device hxtft # Skeleton driver device skel # Pseudo terminals service pty 4 # System log service log # Power control device power signal "POWER_LED" pin RA3 signal "POWER_SWITCH" pin RA4 signal "POWER_CONTROL" pin RA5 # picga controller spi1 # RAM disk: picga device picga0 at spi1 pin RA4 # chip select signal options "PICGA_BUS=SPI1CON" # TODO: delete this option signal "PICGA_CS" pin RA4 # TODO: delete #-------------------------------------------- # Custom RAM disk devices # # sdramp -
