Eeprom driver for mini2440

linux在mini开发板上移植（14）之移植I2C-EEPROM 驱动 Linux 对S2C 的I2C 接口提供了完善的驱动，因此我们只需在内核中配置一下即可使用。. The 24C08 EEPROM (Byte) is connected to the I2C bus: I2CSCL and I2CSDA. JTAG The JTAG is led out on a 10 pin connector with mm pitch. Ethernet The ethernet interface uses a Davicom DM chip. Note: Each board has got the same MAC address. It can be configured by software for Linux and for WinCE inside the BSP DM driver code. Actually, the underlying fb driver is totally ignorant of console rotation. So to have a slightly bigger console font use: MINI # setenv bootargs ${bootargs} fbcon=font:VGA8x8 MINI # saveenv For more fonts check the kernel configuration file root@mini~# cat eeprom.

Mini Hardware. Dimension: x mm; CPU: MHz Samsung S3CA ARMT (max freq. MHz) RAM: 64 MB SDRAM, 32 bit Bus; Flash: 64 MB / MB / MB / 1GB NAND Flash and 2 MB NOR Flash with BIOS. Mini DM 驱动分析（二） 在真正的开始分析dm driver的probe之前，首先来看看dm 驱动中几个十分重要的结构 1、dm_driver static struct platform_driver dm_driver = {.driver = {.name. If you imagine all of the bytes in a Kbit EEPROM standing in a line from 0 to — because there are 8 bits to a byte and therefore you can fit bytes on a Kbit EEPROM — then a memory address is the place in line where you would find a particular byte. We need to send that address to the EEPROM so it knows where to put the.

10 de ago. de 下面我们就以mini的I2C设备at24c08 EEPROM为例，介绍如何完成这两个工作。 The behaviour exposed to Linuxis defined by the driver. Now everything is in place to install the binary OSELAS toolchain for the www.doorway.ru-Pengutronix-Mini board support package. 12 de mai. de mini M nand版本可使用的u-boot. 支持IIC接口EEPROM的操作,并可保存ENV（参考hiboy apt-get install uboot-mkimage.
