devc-con,-n6

Hi…

After I updated with the latest QNX+ (…), the boot process only gives
me 4 consoles when I am asking for 6 of them (never mind that this was
working before):

[pri=10o] PATH=/proc/boot diskboot -b1 -D0 -odevc-con,-n6
-odevc-con-hid,-n4


when I do:

\

pidin ar | grep devc-con

4103 devc-con-hid -n4
471071 grep devc-con

it seems that devc-con is starting in its default state (with four
consoles) and ignoring my request for six with -n6 above (-odevc-con,-n6).

Any ideas on what I am not doing well? How do I force the OS to start 6
consoles instead of default four (4)? Thanks.

Regards…

Miguel.

If you’ve installed 6.3.0 SP3 or the SP2 to SP3 Upgrade, the system starts
devc-con-hid instead of devc-con. The options are similar, but devc-con-hid
also supports USB.

The release notes should probably point out this change (right now they
simply mention the lack of documentation for devc-con-hid). I’ll fix up
the notes.

I’m betting you want:

-odevc-con-hid,-n6

Hi David…

Thanks. This is indeed what I wanted. Too bad it took me so long to
check back here for an answer.

Question: what does devc-con -n do now? Is it obsolete? If it is
not, then what does it do that devc-con-hid cannot do? If it is
obsolete, why is still included in the command line? May be I should
look in the documentation somewhere? :slight_smile: Thanks.

Regards…

Miguel.

Hi Steve…

Yes, you are correct. That is what I needed. I wonder what do you mean
when you say that ‘devc-con-hid also supports USB’ ?

Does devc-con-hid supersede devc-con? If not, when do we use one over
the other? I suppose that I could search in the docs somewhere? Thanks.

Regards…

Miguel.
