Summary: Simple GPIO test fail in BF548-EZKIT

Details:

Simple GPIO test fail in BF548-EZKIT.

When press button, there is no response for simple-gpio-test.

Kernel config is attached. Bellow is the log:

root:/> simple-gpio-test /dev/gpio8

Going to sleep until the gpio goes high.

(if this is a button, you should push it :p)

BF548-EZKIT:

LED1 => GPIO6 PB1 => GPIO8

LED2 => GPIO7 PB2 => GPIO9

LED3 => GPIO8 PB3 => GPIO10

LED4 => GPIO9 PB4 => GPIO11

LED5 => GPIO10

LED6 => GPIO11

Not a bug.

Use the right gpio device node.

BF548-EZKIT connects GPIO_PB8..11 to PB1..4 (SW13..10).

So don't use PORT A GPIOs please use PORT B.

root:/> modprobe simple-gpio

simple-gpio: now handling 160 GPIOs: 0 - 159

root:/> simple-gpio-test /dev/gpio24

Going to sleep until the gpio goes high.

(if this is a button, you should push it :p)

The gpio went high! Time to bail!

could you update the cheat-sheet.h header so there's a BF548-EZKIT section ?

--- Vivi Li 2009-02-18 01:50:19

OK, it works fine. Thanks!

cheat-sheet.h and simple-gpio-game.c are updated.

Close this bug.
