Part Number: SK-AM62P-LP

Tool/software:

Hi,

I’ve added the device name to the EEPROM on the SK-AM62P by writing data to addresses 0x50 to 0x55 at I2C address 0x51.

While I can successfully read this data in U-Boot using the command "i2c md 0x51 0x50 0x55", I'm having trouble accessing the same data from Linux. Can you help with how to read this data from Linux?

I am attaching the screenshot for U-boot:-

Hi Nick,

We resolved our issue.

To write data in 0th address below command:-

==> echo -n -e "Hello World" > /sys/bus/i2c/devices/i2c-0/0-0051/eeprom

To read the entire data use below Command:-

==> hexdump -C /sys/bus/i2c/devices/i2c-0/0-0051/eeprom | head
