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 ------------------------------------------------------------------------------ vRanger cuts backup time in half-while increasing security.
