[beagleboard] selection of correct operating system

2018-08-05 Thread salahgafoor 
HI,

I've a requirement of following things to be done using my beaglebone black 
rev.C running Kernel 4.9


   1. Should have Linux environment
   2. Ethernet, RS232, I2C connectivity
   3. GPIO Interface
   4. LCD Interface
   5. Fast booting

Kindly suggest me a best suitable OS image for above mentioned applications.

I had a bad experience of incompatibility issues when several libraries 
changed when Kernel version changed from 3.9 to 4.9, where I had to change 
my software to make it work in new Kernel version 4.9. Can we avoid such 
problems in the case of beaglebone?

[beagleboard] Re: BeagleBone Black doesn't sometimes start. Only Power LED is on

2018-03-14 Thread salahgafoor 
Hi all,

I've two beaglebone black revC boards with debian 7.9, kernel 3.8 and 
debian 9.3,kernel 4.9 respectively.

I tried to power up these two boards using VDD pins on a board having some 
another interfaces like LCD etc,

But, only first board is booting up(debian 7.9). For second board, only 
power led is glowing.

Please help me on how to debug this

[beagleboard] Enabling UART in new kernel 4.9 with debian OS 9.3

2018-03-10 Thread salahgafoor 
Hi all,

I'm using UART2 channel for serial communication in my bbb. I've modified 
following lines to enable uart2


##Example v4.1.x
> #cape_disable=bone_capemgr.disable_partno=
> #cape_enable=bone_capemgr.enable_partno=BB-UART2

 When I checked the ttyO signals, I could observe following ports


> root@beaglebone:~# ls -l /dev/ttyO*

lrwxrwxrwx 1 root root 5 Jan 28 14:17 /dev/ttyO0 -> ttyS0

lrwxrwxrwx 1 root root 5 Jan 28 14:17 /dev/ttyO1 -> ttyS1

lrwxrwxrwx 1 root root 5 Jan 28 14:17 /dev/ttyO2 -> ttyS2

lrwxrwxrwx 1 root root 5 Jan 28 14:17 /dev/ttyO4 -> ttyS4

lrwxrwxrwx 1 root root 5 Jan 28 14:17 /dev/ttyO5 -> ttyS5


when I tested the uart in loopback mode, I couldn't receive any data at the 
channel.

After that, I've configured the pin manually as follows

config-pin P9_21 uart

config-pin P9_22 uart


And now, I'm getting data over uart. But, the ttyO signals are the same as 
follows.
In my understanding, ttyO should be like this

crw-rw 1 root tty 247, 0 Jan  1  2000 /dev/ttyO0

crw-rw---T 1 root dialout 247, 2 Jan  1  2000 /dev/ttyO2

 
Why it's showing this difference? And what's the actual method to enable 
uart?
My BBB has kernel 4.9 and debian OS 9.3

Hi Wulf Man,

I've added the related dtbo files in /lib/firmware/ and the links I've kept 
in the /boot/uEnv.txt as follows:

###Overide capes with eeprom
#uboot_overlay_addr0=/lib/firmware/.dtbo
#uboot_overlay_addr1=/lib/firmware/.dtbo

But, it didn't help!! :(

[beagleboard] Re: Enable UART pins on BBB with Ubuntu 16.04 Kernel 4.4.68

2018-02-26 Thread salahgafoor 
Hello,

I've also faced the same issue.

Even though I tried editing the /boot/uEnv.txt file, I cannot enable uart

cape_enable=bone_capemgr.enable_partno=BB-UART2


I had to use 
config-pin P9_21 uart
config-pin P9_22 uart

to enable my uart2 channel.

@Zach : Please try the same and let me know. I don't know if it will work 
in Ubuntu.

@Robert or anyone else, why enabling uart in uEnv.txt is not successful 
always?

[beagleboard] Re: Configuring GPIO pins as active high

2018-02-26 Thread salahgafoor 
Thanks @Robert

I could solve the issue by setting active_low value in 
/sys/class/gpio/gpio66

But I think that's not the recommended method.

Comments please!!

[beagleboard] Configuring GPIO pins as active high

2018-02-23 Thread salahgafoor 
Hi,

I want to configure some of my gpio pins (P8_07 to P8_10) of my beagle bone 
black revC board as inputs with active high state.

OS running in my board is Debian 9.3, with Kernel 4.1.
