uClinux 2.4.19 with 8MByte limit

Hello,

I have uClinux 2.4.19 on a linux/m68knommu/platform/5272 CPU that has

16Mbytes of RAM. Everything works fine if no more than 8 Mbtyes of RAM is used.

Any attempt to use RAM past the 8 Mbtyes limits hangs the OS. I can't invest the time to upgrade to a new kernel. Do anyone know in which version or patch this problem was fixed?

Any help would be apprecited.

Mike

Mike,

Which memory allocator are you using ?

Any more detail on "hangs the OS" ?

assuming it's a problem in that kernel version and not something else...

regards,

Maybe you need to increase INITRD size into kernel settings ?

The config.uClibc file in my vendor direcotry contains the line: MALLOC = malloc I did try malloc-930716 and malloc-simple, it did not solve the problem.

The decoded kysmoops details are as follows:

We are not using INITRD. The boot loader we use does successfully use the entire 16MBytes of RAM before uClinux is running.

Kind regards,

Mike
