Cheat and make the /tmp point to the shared memory area…

[type=link] /tmp=/dev/shmem

Programs require the runtime linker (ldqnx.so) to be at a fixed location

[type=link] /usr/lib/ldqnx.so.2=/proc/boot/libc.so

We use the “c” shared lib (which also contains the runtime linker)

libc.so

Include the disk files so we can access files on DiskOnChip

libcam.so
io-blk.so

filesystem required shared libs

cam-disk.so
fs-qnx4.so
[data=copy]

Include a console driver

Okay, and how did you dinit your 486’s boot disk?

My disk is IBM DBOA-2540, may be too old. :cry:
I has been low level format the disk, the problem disappear.(use Maxtor low level format program called “low.exe” in DOS )

My prevenient step of dinit with the problem is here:
1.use fdisk: change->type(77)->start cyl(0)->end syl(523)->loader->boot->save->quit
2.reboot(prompt: Can’t mount )
3.dinit -h /dev/hd1t77
4.mount /dev/hd1t77 /hd
5.cp my.ifs /hd/.boot

may be the IPL don’t support the older hard disk format? :slight_smile:

I have a question about touchscreen.
The board PC : Advantech PPC-150T-RT
15" Embedded LCD Touch Panel
Main Features
15" XGA TFT LCD display
Touchscreen options :

  1. Microtouch’s Capacitive
  2. Resistive
  3. Strengthened Glass
  4. SAW(Surface Acousstic Wave) *With vandal-proof option for public site use
    Analog RGB signal input
    Open-frame architecture

It use /dev/ser4.

my script of config is here:

Photon -D 500 -R 500 -U 20 &
…(font, devi-hirun…, io-graphics…)…
devc-ser8250 3f8,4 2f8,3 3e8,10 2e8,5 &
devi-microtouch microtouch fd -d/dev/ser4 abs &
calib

But when “calib” is running, I press benchmark on top-left corner, the benchmark jump to the bottom-right corner. (normal should be on the botton-left corner )
And I can’t active the button " Press to complete calibration ".
what’s wrong?

If I were you, I’d hit Esc when message appears. It seems to be DMA problem with your HDD - it doesn’t support this feature… :wink:

RTFM, please. ;)

Hi

If I correctly remember, “S” meant that the boot loader couldn’t find the boot image.

Possible reasons-

  1. Your disk geometry is wierd (eg formatted and dinit’ed for LBA and the booted as CHS)

  2. Surface is bad.
