how to dump the currently-used RCW value from u-boot or from linux

[t_alex]

My new board P3041-DS comes with SW1.1-SW1.5 set to 0_0001 which means RCW source is from I2C1 extended addressing.

Is there any way I can dump the RCW value from u-boot or from linux?

(More detail: The issue is when I tried to set RCW from Nor flash SW1.1-SW1.5=0_1101 ethernet networking is working for u-boot but not in linux. So i think

there are some difference in RCW configuration I would like to find out).

Hi,

You have 2 options:

1. U-boot log - the RCW is printed out by u-boot - is enough to have a serial console (set it up to 115200 baudrate) and a working u-boot

2. CodeWarrior - attach to your board using the Attach connection and read the RCW from RegistersView.
