Hi, I am new to this group. Following is a code I tried from Derek Malloy's
videos, to read the gpio pin values. When I run this program I get
"Segmentation fault". I can't make out how it happens. Can anybody help me
out?
#include
#include
#define MAX 128
int readButton(int);
int main()
{
Yes "%s" was the culprit. Changed to "%c".
Thank you all, I didn't expect this huge participation in this forum.

I am new to beagle baord. I have a doubt here. Please help.
In the following line
pinconf[0x217c/4] = pinconf[0x217c/4] & 0x | 0x0004; //
gpio_149
Why do you need the division inside the pinconf array for indexing?

It would be helpful if you could share the code to get PWM correctly?

Hello everyone,
I have been using my BBB without any problem for quite a long time. But,
suddenly the BBB stopped booting up from eMMC. When I connect the board via

I am using BeagleBoard Rev C3 running Ubuntu 11.04. I need to use an i2c
sensor, for my project. By default, i2c-2 channel is disable by the OS,
which is available in the expansion header. Is it possible to use the i2c-2
channel without recompiling the kernel? Please give me your suggestions.
