5"-7" LCD TFT screen

YLmazGNDZ — Thu, 23 Dec 2021 14:37:46 GMT

Hi,

I want to use 5"-7" LCD TFT screens. Is there a suitable integration where I can do this? What do you think I should use? I will do mass production. I am waiting for your well-integrated suggestions to avoid stock shortages and get quick results. I'll check the touchscreen too. I would be happy if there is an integration that does both. Or there are different integrations. Thank you for your interest.

Have a nice day.

NFS boot failed

stamppot — Mon, 07 Sep 2015 12:42:44 GMT

Hi,

I´m trying to get a embedded board design of ours to boot from NFS. It is based on a blackfin BF527. The board itself is functional, but I´d like it to boot from NFS to increase development velocity. I have followed all of the instructions found here: uclinux-dist:nfs [Analog Devices Open Source| Mixed-signal and Digital Signal Processing ICs], but booting still fails with the following error:

TCP cubic registered

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0)

Listening in with wireshark, I can see that no NFS packets are exchanged anywhere. All required drivers for NFS and such are compiled into the kernel, not as modules.

The relevant u-boot commands:

nfsargs=set bootargs root=/dev/nfs rw nfsroot=${serverip}:${rootpath},tcp,nfsvers=3,retry=3 rootdelay=5 nfsrootdebug console=ttyBF0,115200 earlyprintk=serial,uart0,115200
nfsboot=tftp ${loadaddr} ${nfsfile};run nfsargs;run addip;bootm
nfsfile=vmImage

Please advice, as this is starting to drive me nuts.

AD7877-the S/W pointer is appearing away from point of cotact coordinates on touch panel?

Akunhana — Wed, 11 Jun 2014 10:44:25 GMT

Hi,

We are interfacing i.MX6SL EVK board to AD7877 touch screen controller and are using 3.5 inch Screen touch Panel. Touch panel x-axis size is 76mm and y-axis size is 61mm.

While touching on the panel the pointer(S/W pointer) is appearing 2-3mm away from the point of contact.

We would like to know, whether this is a S/W issue Or is it H/W issue (related to the calibration of Ad7877)?

Pls give your inputs

2008-02-04 10:21:12 /dev/ptmx - wrong

Duane Ellis (UNITED STATES)

Message: 50631

The "/dev/ptmx" feature is (pseudo terminals) has a problem.

In the end, the function ptsname() returns a device name that does not exist.

For example if the PTY is 7, it should return /dev/pts/7 -which it does

The device /dev/pts/7 (with the slash) does not exist.

The device /dev/pts7 {without the slash} does exist.

The work around is: muck with the filename returned by ptsname()

Works just fine on x86-linux, but wrong on blackfin-uclinux.

#include <stdio.h>

#include <stdlib.h>

#include <errno.h>

#include <string.h>

#include <fcntl.h>

int

main( int argc, char **argv )

{

char *cp;

int h;

h = open( "/dev/ptmx", O_RDWR | O_NOCTTY | O_NONBLOCK );

if( h < 0 ){

printf("Cannot open PTMX, error: %d %s\n", errno, strerror(errno));

exit(1);

}

cp = ptsname(h);

printf("PTMX Name is: %s\n", cp);

for(;;)

;

}

-Duane.

Message: 50636 Duane:

On the target:

root:~> cat /proc/filesystems | grep pts

nodev devpts

root:~> mount | grep pts

devpts on /dev/pts type devpts (rw)

When I have telnet into the board (activate a pseudo terminal)

root:~> ls -l /dev/pts/*

crw------- 1 root root 136, 0 Aug 6 11:53 /dev/pts/0

root:~> find /dev/ -name "pt*"

/dev/ptmx

/dev/pts

When I run your application (on the target)

root:~> /var/a.out

PTMX Name is: /dev/pts/1

Can you double check that devpts is mounted properly?

>> root:~> mount | grep pts

>> devpts on /dev/pts type devpts (rw)

That seems to make a difference. I did not have it mounted.

I'll have to test my other combinations to see if it is completely fixed.

2008-01-02 14:07:42 JACK on Blackfin?

ADIApproved — Mon, 05 Aug 2013 07:10:20 GMT

Steve Strobel (UNITED STATES)

Message: 49187 I have had several people recommend that I use JACK to handle the audio for my 4-input, 8-output AD1938 project (see <http://blackfin.uclinux.org/gf/project/uclinux-dist/forum/?action=ForumBrowse&forum_id=39&_forum_action=ForumMessageBrowse&thread_id=24943> for more info). Has anyone tried JACK on Blackfin? Any suggestions for simple wave/mp3 play/record utilities that work with it?

Thanks,

Steve

Message: 49314 According to the info: http://jackaudio.org/ - "JACK is a low-latency audio server, written for POSIX conformant operating systems such as GNU/Linux and Apple's OS X", it looks it should be able to be ported to blackfin uclinux.

Message: 50386 Hi all,

I was wondering if anyone has successfully built JACK for the Blackfin?

I am about to attempt it but don't want to re-invent the wheel! Its also been quite a while since I did anything with uCLinux so gonna be a bit rusty.

I've read the 'Porting Apps to uClinux' in the docs section. Any pointers as to porting a daemon to uCLinux would be appreciated.

Thanks,

Rob
