use customized kernel (2.4) on STPC?

Hi,

We compiled a kernel on a desktop with RH 7.2 Linux (kernel 2.4.7-10)and wanted to load this customized kernel to a DOM on an STPC Consumer II evaluation board.

However, the kernel could not boot, and stopped right after the message indicating freeing unused memory. (no INIT: ... message). However, same DOM could boot on a Pentium III machine where the kernel was compiled.

We tried the same board, but with an earlier linux kernel version 2.2, it could boot.

Anybody out there has any hints on what might go wrong?

Thanks,

JP

Did you check if your kernel have been compiled for 486 architecture?

By default, the kernel is configured to be compatible with your compilation platform which is usually a pentium class CPU.

Take a look on the 'Processor type and features' section and select 486 as Processor family.

I also suggest to suppress 'Symmetric multi-processing support' to avoid problems during the compilation. This option require some other module you could have suppressed.

In fact, all options from the 'Processor type and features' section are not available on 486 and you could suppress all of them to decrease the size of your kernel.

Hi jdong

Forget 2.4.7, try a newer kernel.

Old Kernels (Suse 7.1, 2.4.10?) hat problems with USB, failing to boot with the STPC Atlas evaluation board.

Today we are using standard 2.4.20 from kernel.org, because due to a packet reassembling bug before, nfs had performance problems.

Dont rely on the bios:

CONFIG_PCI_BIOS=n

CONFIG_PCI_GOANY=n

Best regards
