Hello,
I found Flash Device driver related files in linux-2.4.3-pre3-2001-03-11
I have Intel TE28F160B3(2MBytes, 16bit port size, bottom boot type) flash memory.
Question1:
Can I use my intel flash memory for your flash device driver?
I got flash vendor id : CFI_VENDOR_INTEL_STANDARD
so , I modified your code like this.
} else if ((primary_vendor == CFI_VENDOR_INTEL_SHARP_EXTENDED) ||
(primary_vendor == CFI_VENDOR_INTEL_STANDARD) ) {
Is it possible ??
Question2:
when kernel booted, I found this messages.
Found 1x16bit 2MBytes CFI Flash device of type Intel Standard at 0xFFE00000
registered flash device /dev/flasha (minor 0, 4 partitions)
and when I got shell prompt. I made like this.
mknod /dev/flasha c 60 0
mknod /dev/flasha1 c 60 1
mknod /dev/flasha2 c 60 2
mknod /dev/flaaha3 c 60 3
mknod /dev/flasha4 c 60 4
I tried like this.
ls -al >> result.txt
cat result.txt >> /dev/flasha4
cat /dev/flasha4
but I coudn't find my result.txt contents..
Is it impossible??
Questions3:
I read your README but I had a question.
Where can I find flash_erase ??
W. Denx wrote flash_erase /dev/flasha start_addr end_addr
Thanks for any comments and replyings...

Hi,
Did anyone have stability problem with MontaVista's kernel
2.4.0=test2-1.2.2-1 ??? I'm running it on a board similar to Sandpoint
with a 7400 processor and sometimes it crashes because "current->mm ==
NULL" (from do_page_fault).
I'm not using any initrd but a shell (ash) instead. This seems to
happen when I run a lot of programs in my script. I also seems to be
related to a synchronisation problem since it gets a lot more stable
when I add "printk"s in the functions switch_mm and activate_mm.
This could also be related to the fact that I'm running in little-endian
but since it only crashes once in a while, I would doubt it! So I'm a
bit suspicious about this test kernel, did anybody else have problems
with it??
Sébas..

That version of the kernel does have problems. Get the latest linuxppc_2_5
source and try that. I haven't tested the last couple weeks but before then,
it was very solid. Sandpoint support is in it.
