Can RCW be configured to boot from NOR

[muaxi8]

Can the T4240 custom board be configured to boot from NOR Flash ? and if so, what is the address of

NorFlash programming RCW? I don't see that address in the document 《QorIQ-SDK-2.0-1703-IC

Rev0.pdf》

Documentation is given for programming RCW from I2C eeprom。

I used CodeWarrior to program RCW to the 0xe8000000 address, but the board wouldn't bring up

RCW is put at the begging of NOR flash.

In u-boot, RCW address is 0xE8000000.

In CodeWarrior initialization file C:\Freescale\CW_PA_v10.5.1\PA\PA_Support\Initialization_Files\QorIQ_T4\T4240QDS_init_sram.tcl, NOR flash is defined as the following.

# 0xE8000000 0xEFFFFFFF TLB1_4 NOR 128M

So in CodeWarrior, RCW address is also at 0xE8000000 .

You could reset the target board and dump NOR flash to check whether the read RCW image is correct.
