Hi @harisankar2001 I will write detailed comments,
It seems like you are facing an issue with reading the Part Number from DIMMs on LA1224RDB using the decode-DIMMs command. The error message you are encountering suggests that the kernel might not support your hardware.
First, let's ensure that your kernel has the necessary I2C support enabled. You can check this by running the following command:
grep I2C /boot/config-$(uname -r)
If you see the I2C support is enabled (marked with 'y' or 'm'), then proceed to the next step. If not, you will need to recompile your kernel with I2C support enabled.
Next, make sure that the i2c-dev module is loaded. You can load it by running:
sudo modprobe i2c-dev
Now, let's check if the ee1004 driver is loaded correctly. Run the following command:
lsmod | grep ee1004
If the output shows the ee1004 module, it means the driver is loaded. If not, try loading it again using:
sudo modprobe ee1004
Once the ee1004 driver is loaded, try running the decode-DIMMs command again. If you still face the same issue, it's possible that the EEPROM on your DIMMs is not supported by the ee1004 driver. In this case, you might need to look for an alternative driver or method to read the Part Number from your DIMMs.
