Hi,
I'm using a Redhat 6.1 kernel (2.2.12-20), and a ISA board with memory from
0xe00000 to 0x1000000.
I'm writing a driver to this particular board and I'm not able to access to its
memory.
A similar driver already work on the same PC with Lynx OS, so it is not a
question of hardware compatibility.
I try to use adresses 0xc0e00000 to 0xc1000000 directly in my module, but it
dosen't work.
I also patch my kernel : file arch/i386/mm/init.c, function mem_init with
code found in "Linux device driver" from alessandro rubini, but it doesn't work
also.
What's going wrong ? How can I be sure to acces to this board memory ?
Thank you in advance
Best regards,
Michel
