IBL Size

Senthil Kumar

Hi,

We are integrating few functionalities in existing IBL for our custom board. After the integration, the IBL binary file size may go above 64 KB. It seems RBL and eeprom communication through i2c is 2 byte addressing. So only 64 KBytes access is possible with 0x50/0x51 address.

Will RBL support 3 byte addressing mode in i2c to read/write eeprom greater than 64 Kbytes.

It is not supported. It will require a two stage boot.

If the image is bigger than 64k a two stage boot would be a good idea anyway. The ROM runs the I2C bus at a slow rate. A two stage boot lets you enable the PLLs and run the I2C at the max speed that your EEPROM can take.

Rahul
