Hi , I have EN29LV640H flash (http://www.eonsdi.com/pdf/EN29LV640.pdf)
On my mpc83xx board.
How can I write data to flash from linux.?
I guess it done with mtd , there is an example somewhere?
Thanks.

I have mpc83xx, and I work with Linux 2.6
I am trying to use power management states.
I succeed to get into D1 state (echo standby > /sys/power/state),
And to waked up by GPIO.
But when I try tried echo mem > /sys/power/state it waked up by reset
(that stuck in the middle)
Or echo disk > /sys
I have mpc83xx,
I saw that I need to use swab32 to any read\write operation from registers,
I don't understand why I need it?
Do I need it for all registers?
Why in the mpc8313 reference in registers description some bits look like
31,30,29,.,3,2,1,0
And some: 0,1,2,3.,30,31
Is it just mistak
myirq=74

I want to receive interrupt from 1 GPIO port (for example 14)
I changed the GPIMR to 0x (so I need to get interrupts from all GPIO
ports)
And then request the irq by :
irq_create_mapping(NULL,74);
request_irq(74,handler,IRQF_DISABLED,"GPIO",NULL);
the return value is 0 (OK)
but I c
All I had to do was to add :
irq_create_mapping(NULL,71)
and yes it not the exact code , I work with 2 computers...
thanks.
