Embodiment Construction
[0017] The present invention provides a method for quickly debugging DDR memory particles through U-Boot:
[0018] Modify the DDR initialization part code in U-BOOT, so that DDR in U-BOOT obtains the SPD information part, and replace the written SPD array with the storage location of the SPD data in the EEPROM read by I2C pointed to by the spd pointer , so that there is no need to program the EEPROM each time to speed up debugging.
[0019] The present invention will be further described in conjunction with the accompanying drawings.
[0020] Using the method of the present invention, at the get_spd position in U-BOOT's / driver / ddr / main.c, ret is forced to be set to 0, and the SPD data is saved into the array in the form of a hexadecimal array, which is the written SPD array ,
[0021] Then overwrite the array to the storage location of the SPD data read through I2C pointed by the spd pointer through memcpy, refer to the following code example:
