Problem with PQ2FADS BSP

QNX Newsgroups (Archives) qnx.bsp

Hello,

I have flashed the 8M binary image to an MPC8272ADS develoment board
but I do not get any response (via the serial connection) when trying
to execute. I have followed the directions in the “Freescale PQ2FADS
Board Support Package” documentation and it appears the image is
running (run LED stays lit) but I cannot verify serially.

I am utilizing the usual HyperTerm over COM1 (windows host).

Any ideas?

Thanks…

Some things to try, or make sure of:

-the binary image that you generated and flashed was exactly 8Mb (8388608 bytes)
-you’re using a straight through serial cable, not a null-modem cable
-the Hyperterminal baud rate is 57600, no flow control
-the serial cable is connected to the upper D-9 connector on the board

Also, these boards don’t seem to always execute right when power is
applied; I’ve found with the PQ2fads board that sometimes it’s necessary
to depress switches SW2 and SW3 simultaneously, to generate a hard reset.

Hello,

Which version of the BSP are you using? There was a specific update
done to the BSP to add 8272 support
(bsp-freescale-pq2fads-1.0.2-20051041307-*).

You may also be seeing one or both of the following symptoms listed in
the release notes for this BSP:

  • The mkefs command for Windows doesn’t handle redirection properly.
    (Ref# 19065)

Workaround: In the images/make_flash_img directory, change the following
code:

mkefs …/src/hardware/ipl/boards/pq2fads/pq2fads.efs
ipl-ifs-efs-pq2fads.bin

to

mkefs …/src/hardware/ipl/boards/pq2fads/pq2fads.efs efs-pq2fads
cat efs-pq2fads >> ipl-ifs-efs-pq2fads.bin
rm -f efs-pq2fads

  • In order to build the IPL for the MPC8272ADS board, you have to pass
    “make MPU=8272” on the command line.

Thanks,
-Jay.

Thanks for the information. Sorry for the late response but I found
that SW5 was not setup properly. Once I moved the switches, all came
up OK…
