retrieved, amongst other things.42We first try to get the information from SMBIOS. if we don't find it43there, we have to read from arbitrary I/O ports to probe for such44interfaces. this is normally safe. do you want to scan for IPMI45interfaces? (YES/no): yes46Probing for 'ipmi bmc kcs 'at 0xca0... no47Probing for 'ipmi bmc smic 'at 0xca8... no48 49 Some hardware monitoring chips are accessible through the isa I/O ports.50We have to write to arbitrary I/O ports to probe them. this is usually5

interface module integrates UART, SPI, I2C, and other interfaces, which can be used to communicate with other systems, making the interface module A universal interface converter. The system hardware architecture is shown in figure 2. 3 USB firmwareProgramDesign The USB firmware program of the system module adopts the GCC compiler design that complies with the ansi c standard, and combines hierarchical modular structu

Openmoko gta03 smartq5 initi6410 bootloader Qi reading and analysis of enterprise-level bootloader (I)(For more information, see the source. It cannot be used for commercial purposes) (Welcome:Www.embed-training.com/) As openmoko 0 xdroid's open-source man jserv said: the use of Qi is not limited to the openmoko freerunner hardware platform. The smart device changes the original openmoko gta03 bootloader code to its smartq series. The advantage is that it is used to burn the file system. Qi wi

Kernel 3.1 introduces a new set of API Regmap to extract the common parts of related registrations, enabling, and reading and writing about the I2C SPI IRQ to improve the reusability of the code and make it easier to use when using the kernel-like infrastructure components. 0 Basic Structure struct Regmap_config { int reg_bits;//register address number of digits, must be configured, such as I2C regis

In the drive development process, we sometimes encounter this application: for example, the firmware of a chip is not fixed, can be upgraded later. Then, every time the system is powered on, a test is required, and if a new firmware is detected, the firmware is upgraded the first time it is powered on. After that, because a new firmware version number is saved for detection, no more boot upgrades are available. Take a I2C touch screen chip For example
