I’m starting an evaluation of PowerPC MPC8540 and experimenting
problems in starting QNX.
Here is my setup:
Here is the problem:
The metrowerks comes with the U-boot boot loader, which is claimed to
be able to boot QNX.
I generated an OS image in Momentics.
I can download this image into RAM via TFTP.
Whenever I try to start QNX the system reboots or
freezes.
For tftp download make sure that the image is raw and not srec.
You should be downloading the image to addr 0x100000, also provide this
address with the go command.
Regards,
Joe

problems in starting QNX.Here is my setup:
- Metrowerks evaluation board PCI-8501 (with MPC8540 processor)
- QNX 6.3.0
- mpc85xads binary BSP
Here is the problem:

Here is the console ouptut from startup to freeze!

Everything seems to be ok until I try to start QNX. I’m currently
looking at the serial port configuration in the boot script file:

What version of the BSP are you using?
Is the CCSRBAR in the correct location (try specifying the “-c” option
to startup)? (This changed from 0xFDF00000 to 0xE00000000 in the newest
release of the BSP given the change in the default memory map for U-BOOT).

For pre-1.1.2 U-BOOT ROM Monitors, change 0xe0004500 to
0xfdf04500.
330000000 corresponds to the CCB clock frequency, which may change
depending upon board dip switch settings.
