 EEPROM / I2C Commands

Katana®752i User’s Manual

The icrc32 computes a CRC32 checksum.

icrc32 chip_address[.0, .1, .2] count

The iloop command reads in an infinite loop on the specified address range.

iloop chip_address[.0, .1, .2] [# of objects]

The imd command displays I

2

C memory. For example:

imd 53 1800.2 100 

displays 100 bytes from offset 0x1800 of I

2

C device 0x53 (right-shifted 7-bit address). The 

.2

 at the end of the offset is the length, in bytes, of the offset information sent to the 

device. The serial EEPROMs all have two-byte offset lengths. The RTC has a one-byte offset 
length. The temperature sensors have zero-byte offset lengths.

imd chip_address[.0, .1, .2] [# of objects]

The ipmifirmload command reloads the IPMI controller firmware from an image held in the 
monitor image. The optional boot and run arguments specify to reload the firmware from 
an image held in memory.

ipmifirmload [boot boot_image_addr] [run runtime_image_addr]

The imm command modifies I

2

C memory and automatically increments the address.

imm chip_address[.0, .1, .2]

The imw command writes (fills) memory.

imw chip_address[.0, .1, .2] value [count]

The inm command modifies I

2

C memory, reads it, and keeps the address.

inm chip_address[.0, .1, .2]
