Explain in more detail why it doesn't work?
It works here and I am sure for others?

I did, but it doesn't work. Anyway, how to set the serial F on PE2 and
PE3?
The documentation says yes and no in different tables/figures as I said
before.
RCM4000: Ethernet and serial

It can't work because the PE2 and PE3 are not connected to the 50-pins
connector.
If you look at the schematics of RCM4000 you will see they are configured to bring signals to NAND flash.
Instead the RCM4010 is sold without the NAND flash (and with a couple of 0R0 installed) so the PE2 and PE3 are available.
Honestly I didn't understand this reading the user manual. I had to check the signals' path with a multimeter and then I got confirm from the schematics.
So, are you sure you can use serial F on PE2/PE3 with RCM4000?

The IO Config tool doesn't always make code that works.
Sometime (and yes, I reported this to Rabbit, and they agreed) it makes byte-wide writes to the some of the configuration registers which should really just be bit-wise, which blow away existing bits in those registers causing the processor to just hang.
I see this often, and always use the IO Config tool as a basis and then twek the code it generates.
I can't remember the specifics but it happened to me anytime I was using all the serial ports on an rcm4000
I'll see if I can find the old code....
