Hello!
I am using linux kernel 2.4.18 with included MTD drivers. I got working
Intel Strataflash on our experimental board with physmap driver.
When i write something directly to flash, using "cp" command
(cp ./image /dev/mtd0), then system hangs *after* data is written.
Command returns to shell prompt, but system does not respond any more.
Debug messages from mtd do not indicate any errors.
jffs seems to be working OK.
Any ideas why this happens? Any suggestions for debugging?

Does not respond even to this. Otherwise "magic key" is OK.
Any other suggestions?

- use mtdblock0 instead of mtd0.
- external debugging (some jtag controller, like riscwatch)
- printk()s, if you have the time
