Hello,
I replaced an old MPC8533 by a new MPC8533, but the PCB does not work. Is there any possible that the old MPC8533 has firmware/software on it? The new MPC8533 is the blank one, does not have firmware/software on it hence the PCB does not work?
Thank you
No, please refer to MPC8533E Reference Manual, 4.4.2 Power-On Reset Sequence
and MPC8533E PowerQUICC®™ III Bring-up Guide to debug the issue.
Thanks
