Hi everyone,
I am setting up my tools for an MPC5200 based device I have designed. I have been using these tools (which like all development software here, are my doing) on the MPC8240, on the MC68340, and some others (TI, Xilinx parts) but now the 5200 seems to be more stubborn than they usually are. The problem I am stuck with since yesterday is the fact that I cannot preload the boundary scan register (BSR) with a value. I can read it allright and I do read the actual states of the signals, but the data I shift into the 5200 BSR does not appear to influence the BSR at all, next read I get the same value I had prior to the preload, with perhaps some input value changed (I have a few floating). I can also read the ID code allright, and the device responds to its high-Z command prior to the first BSR shift I do; after that, power cycling is the only way back to highz, although reading the inputs still works. I have the bsdl file and the 5200 UM files; so far I have no clue what I am doing wrongly. It may be just that it's been a while since I last messed with my JTAG software (not very likely, I am already pretty much in it again, and it is not huge). Anyone with any knowledge on that?
Thanks,
Dimiter
