WB-IMX233-CORE is a processor module. Made on the basis of IMX233-OLinuXino-MICRO design with minor changes

processor Freescale i.MX233 - ARM926J 454Mhz
64 MB RAM
microSD slot
SPI, I2С, UART, GPIO, JTAG

Differences from IMX233-OLinuXino-MICRO

revision C3 uses SAMSUNG K4H511638J-LCCC memory. The memory operates in the mode CL=2.5@133Mhz,

that requires modification of The u-boot loader. Modified u-boot: https://github.com/contactless/wirenboard/blob/master/contrib/u-boot/u-boot.sb.cl25

revision C3-H uses Hynix memory, the settings are above
revision C3-A uses Alliance memory, u-boot: https://github.com/contactless/wirenboard/blob/master/contrib/u-boot/u-boot.sb.new.cl25.pwr1

Pins used by the bootloader

The following pins must have a specific state at boot time:

Name	position	GPIO	state	pull-up/pull-down
LCD_D03	6@CON1	35	high	3k3 up
LCD_D02	5@CON1	34	low	22k down
LCD_D01	4@CON1	33	low	22k down
LCD_D00	3@CON1	32	high	3k3 up
LCD_RS	27@CON1	51	high	47k up
