Michael, thank you for replying,

Although I work in electronics, hard and soft (or firm, better said) for 
more than 40 years (I saw the birth of the first microprocessor, the 
Intel 4004), I must confess that I know almost nothing of jtag and 
boundary scan.

That said, this thing is driving me nuts; I have also tried openocd with 
no results; I can't get it to halt.

One thing I can't understand, for instance, is why urjtag detects a chip 
with irlen of 8 when I know the core cpu is an arm926ejs with an irlen of 4.

So, I guess you won't be surprised if I confess that I don't know what 
you mean by "if every pin your flash is connected, can be controlled via 
boundary scan"

jss
