1. The IPMB based on the physical I2C implementation, and the agreement's orders to IPMI IPMB transfer request and the response is written based on the way (that is in charge of I2C writing ways to do from the I2C send written orders), so if a IPMB bus to implement two I2C bus? Otherwise, the written response how to through the main way to send back?
2. Do the case management SHMC with normal BMC in development have to differ?

CodePudding user response:

Reading data from the machine cycle, I2c host at the end of the command is to read command, or must't get data from the machine

CodePudding user response:

SHMC is when to send the request to the host, after sending the request immediately after the switch to the I2C send the response from machine model wait IPMC, accordingly, IPMC free cases I2C from machine model, after the IPMC receives the request from SHMC, to switch to the I2C host, to SHMC write response, after writing the response, IPMC again to switch back to the I2C from machine state,
The host in the communication protocol I2C address (rqAddr) is used to write to the SHMC IPMC response to use,

CodePudding user response:

What are you doing and also recently in BMC, can leave a contact number

CodePudding user response:

Can I leave a WeChat, BMC research study together

CodePudding user response:

Is the I2C controller generally have four patterns: Lord, Lord closed; From the hair, from the closed
Is the role of the primary and secondary depending on which side of the clock the clock line is to be;
So the Lord accept the meaning of active reading is the main equipment cache the value of the
And from a signaling is the beginning of each main equipment launched mass, then from the device to write data in the cache, waiting for the master signal transmission to complete it again refresh cached data

CodePudding user response:

I2C controller generally have four patterns: master, the Lord closed; From the hair, from the closed

So send out the request switch into slave mode can be waiting to receive immediately, this is no problem,

refer to 4th floor, persistence is a kind of life attitude response:

can I leave a WeChat, BMC research study together

can add me, I am familiar with this

CodePudding user response:

refer to 7th floor with wave current response:

Quote: persistence is a kind of life attitude reference 4 floor response:

Can I leave a WeChat, BMC research study together

can add me, I am familiar with the

How to add you? I hope can exchange together

1, PMB physical layer based on I2C implementation, therefore, a IPMB bus to implement two I2C bus, namely by the SDA and SCL line connecting the upper machine and lower machine, so as to realize the communication of IIC,
2, should be BMC's protocol format is different, the rest of the great court
