Dear All,
Please let me know process to I2C EEPROM boot of MPC8323ERDB board.
I have the I2C EEPROM (0x50) working in u-boot as well as in Linux stage.
Our requirement is as follow:
Whenever our MPC8323ERDB board fails the NOR boot in R & D or in the trail, we can boot from I2C EEPROM without JTAG/external cable connection.
Please let me know the which uboot file need to write in the I2C EEPROM and what is the compilation procedure and what setting is required in the hardware/software to boot from I2C EEPROM.
I am using SDK1.7.
EEPROM part number Inventory PROM 24LC01BTISN.
Thanks,
Sagar
We recommend using SDK 1.9 or SDK 2.0 for LS1021 or LS1043 boards.
These SDKs support eMMC loading for LS1 boards.

Have a great day,

Pavel, can this information be used for the LS1 boards to boot from eMMC if the board has an eMMC?
Sorry for delay.
Look at new attachment.
Use this software for EEPROM file generation.
Have a great day,

Dear Pavel,
Can you send me procedure how to generate specific file for boot sequencer.
I got .cpp file there, cross-compiled, but do not know which file need to flash in the EEPROM and how to generate it.
Thanks,
Sagar
Look at attached files.
Have a great day,

SDK 1.7 does not support the MPC8323 processor. NXP offers LTIB Linux BSP for the MPC8323E RDB board:
It looks like that this BSP can be used for your board.
The boot sequencer provides the means to load the hardware reset configuration word and to configure any memory-mapped register before the boot-up code runs. The MPC8323 does not have possibility to boot from I2C EEPROM.
See the MPC8323 Design Checklist:
