RPX Lite only seeing 16MB RAM

Is there a way to persuade the RPS lite startup that there is really
64MB RAM, and not 16?
The board (one from Embedded Planet) definitely has 64MB RAM,
but the OS only reports 16.
IS this a hardcoded limit? Or should the startup pick it up
by itself?
If possible, I would prefer not to have to have the source
to have to modify this.

Yep, it’s a hardcoded value in the startup code. You can just build a
custom version of startup for you version of the RPX lite with a different
value. But since you wish not to do this, you could also use the -M option
to startup to specify addition memory to startup.

OK thanks

We’ve tried -M 16777216,50331648,1
(start at 16MB, for 48MB, RAM)
or -M 0x01000000,0x03000000,1

This didn’t work. Board booted ok but still only reported
16MB.

When you add -vvv to startup, what does the asinfo area report (with and
without the -M option).

Well, the code is there, and the -M option should just work.

Have you verified you sure you’re rebuilding the image and uploading the new
one?

Yes, the image is definitely updated, this was verified explicitly.
Customer will check to see if OR register is changed between
what the PlanetCore sets up, to after the OS has taken over.
Also tried smaller sizes than 48M (8M & 16M) which all didn’t
make a change.

There is an issue which was fixed after release with adding info to the
asinfo syspage entry properly. Should teach me to look at the release
version and not just current.

Let me know how you make out.
