Dear All
While board bring up in custom board iam getting below mentioned error
I2C: ready DRAM: DDR: failed to read SPD from address
It seems you are using a DIMM for your memory (as opposed to directly soldered on the board).
Simply put, DDR DIMMs have a small EEPROM which contains data about the device. You access the SPD EEPROM via an I2C address. If the DIMM detection code talks to this address and does not detect correct data, then you have the problem you are encountering.
Since you are using a custom board, you should read your specs or ask your HW people about the correct SPD address.
I googled it but i am un able to rectify it.. Please resole ASAP manukumar
All the best, RgC
