SubjectPCMCIA problem: writing to Intel Flash Series 2+
Summary:

I can read, but not write to or erase, an Intel Series 2+ flash card.

In the event of a reply, please Cc to my email address, as I am no
subscribed.

Hardware:

Toshiba Tecra 8100 laptop
Intel Series 2+ flash memory card

Software:

Linux 2.4.17
pcmcia-cs-3.1.33

Detail:

When I insert the flash card, the card is correctly recognised and the
appropriate modules load. If I do a "cat /dev/mem0c0c" I get a load of
gibberish on the console, which I assume indicates that I am reading
from the card.

If I attempt to format the card, I get the following error:

$ ftl_format /dev/mem0c0c
Partition size = 8 mb, erase size = 128 kb, 1 transfer units
Reserved 5%, formatted size = 7755264 bytes
Erasing all blocks...

block erase failed: input/output error
format failed.

Querying the card, I get:

$ ftl_check /dev/mem0c0c
Memory region info:
Card offset = 0x0, region size = 8 mb, access speed = 150 ns
Erase block size = 128 kb, partition multiple = 128 kb

No valid erase unit headers!

The following gets reported to the log:

kernel: iflash2+_mtd: erase timed out!
kernel: CSR = 0x0000, BSR = 0x4040, GSR = 0x0606

Is there any other info that would be useful?

Thanks in advance...

josh.
