Re: MPC860 CP / CPM Misbehaving

In message [ref] you wrote:

The SDRAM timings (UPM registers) are setup by a BDM/JTAG debugger script.

The UPM setup is only half of the story. Please check with your SDRAM
manufacturer's manual for the _complete_ initialization sequence that
is necessary on your chips.

The same script is run when I download the other software, which works.

This is no indication that the setup is right. We have seen pSOS+ and
VxWorks running fine on some systems, and Linux  constantly  crashing
on the same hardware because of bad SDRAM initialization. See the FAQ
section in the DULG.
