so have you figured out?
do KERNEL_MODULE_AUTOLOAD and KERNEL_MODULE_PROBECONF work?
if not, you can surely write into /etc/modules-load.d/ within a bitbake recipe in a do_post_install stage

Re: White Dots intermittently on TV
That's what I thought, ie microwave or central heating thermostat (external sources). But the heating hasn't always been on, I have tried the nuc in a different room, on a different ring main. Also, I have never seen this while running a Mygica 510b with transparency.
I was thinking of the internal fan, but, that is running all the time. As for temperature, the device doesn't have to switched on very long before it happens.
Thanks

Re: INTEL DH55TC Desktop board (Intel Core i3 540) and Windows 7 x64 Professional SP1 does not work with 16 GB of RAM
Hello Kevin, thank you very much for your answer.
I think that memory are full compatible. As I mentioned in my post, BIOS recognize all the 16 GB of RAM, if init with CENTOS 7 Live CD works perfectlly with 16 GB, even forcing a full read of memory RAM.
Only fails with Windows 7 x64 Professional.
This is why i can't understand what is happened.
I have been searching for bugs in Windows 7 but nothing founded relative to this issue.

Re: ADC analogue pin value too high
Hi CMata,

When the tmp36 is connected to Galileo my multimeter reads 1.35v and when it is not connected it reads 0.7v

NUC 5i5RHY cold boot - no video, no WOL
I just setup a NUC 5i5RHY and I have a problem. If I power-on NUC after few hours (cold boot) I have no video ( I need to power on manual the monitor) .Restarting NUC, or boot after few minutes after a power-off works fine.
RAM: Kingston Hyper X Impact (HX316LS9IBK2/8)
SSD: Samsung 840 Pro (SATA), Samsung 850 EVO (M2).
Also WOL don't work (before cold boot LEDs form LAN port are off on NUC and LED form router for NUC is also off)
WOL works ok if I restart NUC after few minutes, but after few hours is dead no LAN power, no WOL ...
Please tell me if I have a defective unit, to start RMA.

Re: D54250WYK dead? No
Funny thing is that it was working alright with and without bios pin. Yesterday out of the blue it turned off and now does no matter what I do blue led blinks only ONE time. No singal beeps, no 3 beeps when no ram etc. It just blinks once which is annoying because there is no code for that.

Re: FTDI USB Driver "kernel-module-ftdi-sio" Edison does not assign ttyUSBx to a USB - RS422 FTDI cable
I now have all the parts to build the thing. I have $2,000 worth of parts that I can't get it working because there is no FTDI driver. So I followed your refereence on BPS Building Error and was determined to give it another try.
The relevant post is this:
And by the way, I think I've found the root cause of that.
In the libwebsockets recipe there's a hardcoded reference to sysroot location specific for 64-bit host OS
So if you change the "x86_64-linux" in the below recipe line according to what the name of that directory is on 32-bit system (don't have one at hand to try), I think it's going to work fine.
export OPENSSL_CONF=${TMPDIR}/sysroots/x86_64-linux/usr/lib/ssl/openssl.cnf
This is line 22 in the recipe file at
edison-src/device-software/meta-edison-distro/recipes-connectivity/libwebsockets/libwebsockets_1.23.bb
I cannot find the libwebsockets recipe anywhere. I did a grep for the suspect line in all the files I downloaded and no hits. I did a search for libwebsockets in the instructions and that word is not in there. Where is it?
EDIT: This directory edison-src/device-software/meta-edison-distro/recipes-connectivity/libwebsockets does not exist.
The string x86_64-linux occurs in 102 places under edison-src
Can someone give me a way to build a kernel with a FTDI driver that works PLEASE!
PS. AlexT_Intel has a blog and suggested I follow his recipe which I did. I posted my results there but the quick summary is that it doesn't work either and it seems from the blog that the process has not been tried in ww05-15 but "should" work.

Re: Speed of GPIO using MRAA via Javascript GEN2 Galileo

}
function runMain()
{

Re: Can't enter WEP key in Hex
Added detail...
systemctl enable wpa_supplicant - execute this after you get it working, so it auto-loads the supplicant at the next reboot
And, boy, am I glad I posted my solution here 5 months ago - it was a great reference when I needed to do this again, long after I'd forgotten how.

PWM to ESC
Hi everyone!
I'm looking into getting a brush-less motor to spin from my Edison using the Sparkfun PWM Block, from the PWM i'm linking over to a Simon 12A ESC to the Motor.
I have connected all the parts up, putting the yellow/white receiver wire into the PWM Blocks SIG on CH0, I have then started on the MRAA code side in C++.
My tests are bassed off (Georgi Todorov, PCA9685) stuff. So far I think the PWM Block is found and being written to (I get MRAA_SUCCESS returned).
Here is my code so far (but no response form the ESC);
#include <iostream>
#include <string>
#include <mraa.hpp>
#include "Motor.h"
using namespace std;
mraa::I2c* i2c;
mraa_result_t retval;
void reset(void) {
if (retval == MRAA_SUCCESS) i2c->writeReg(MODE1, 0x00); //Normal mode if (retval == MRAA_SUCCESS) i2c->writeReg(MODE2, 0x04); //totem pole cout << "reset out: " << retval << endl;
}
void setPWMFreq(int freq) {
uint8_t prescale_val = (CLOCK_FREQ / 4096 / freq) - 1; if (retval == MRAA_SUCCESS) retval = i2c->writeReg(MODE1, 0x10); //sleep if (retval == MRAA_SUCCESS) retval = i2c->writeReg(PRE_SCALE, prescale_val); // multiplyer for PWM frequency if (retval == MRAA_SUCCESS) retval = i2c->writeReg(MODE1, 0x80); //restart if (retval == MRAA_SUCCESS) retval = i2c->writeReg(MODE2, 0x04); //totem pole (default) cout << "setPWMFreq out: " << retval << endl;
}
void setPWM(uint8_t target, int value) {
setPWM(target, 0, value); // value 0 - 4095. More like value (0 - 3838)
}
void setPWM(uint8_t target, int on_value, int off_value) {
i2c->writeReg(LED0_ON_L + LED_MULTIPLYER * (target - 1), on_value & 0xFF); i2c->writeReg(LED0_ON_H + LED_MULTIPLYER * (target - 1), on_value >> 8); i2c->writeReg(LED0_OFF_L + LED_MULTIPLYER * (target - 1), off_value & 0xFF); i2c->writeReg(LED0_OFF_H + LED_MULTIPLYER * (target - 1), off_value >> 8);
}
int getPWM(uint8_t led){
int ledval = 0; ledval = i2c->readReg(LED0_OFF_H + LED_MULTIPLYER * (led - 1)); ledval = ledval & 0xf; ledval <<= 8; ledval += i2c->readReg(LED0_OFF_L + LED_MULTIPLYER * (led - 1)); return ledval;
}
void setAllPWM(int last, int value) {
for (int ii = 0; ii < last; ii++) { uint8_t t = ii; setPWM(t, 0, value); }
}
int main()
{
cout << "--Motors----------------------------------" << endl; i2c = new mraa::I2c(1); cout << i2c << endl; retval = i2c->address(0x40); cout << "address:" << retval << endl; if (retval == MRAA_SUCCESS) { setPWMFreq(400); reset(); setPWM(0, 700); // read this does something (but nope) int data = getPWM(0); cout << "-- data:" << data << endl; setPWM(0, 2000); // maybe this? nope also data = getPWM(0); cout << "-- data:" << data << endl; } else { cout << "failed:" << endl; } cout << "exiting Motors" << endl; while (1) {} return 0;
}
With a simpler header of:
#include <mraa.hpp> #define MODE1 0x00 //Mode register 1 #define MODE2 0x01 //Mode register 2 #define SUBADR1 0x02 //I2C-bus subaddress 1 #define SUBADR2 0x03 //I2C-bus subaddress 2 #define SUBADR3 0x04 //I2C-bus subaddress 3 #define ALLCALLADR 0x05 //LED All Call I2C-bus address #define LED0 0x6 //LED0 start register #define LED0_ON_L 0x6 //LED0 output and brightness control byte 0 #define LED0_ON_H 0x7 //LED0 output and brightness control byte 1 #define LED0_OFF_L 0x8 //LED0 output and brightness control byte 2 #define LED0_OFF_H 0x9 //LED0 output and brightness control byte 3 #define LED_MULTIPLYER 4 // For the other 15 channels #define ALLLED_ON_L 0xFA //load all the LEDn_ON registers, byte 0 (turn 0-7 channels on) #define ALLLED_ON_H 0xFB //load all the LEDn_ON registers, byte 1 (turn 8-15 channels on) #define ALLLED_OFF_L 0xFC //load all the LEDn_OFF registers, byte 0 (turn 0-7 channels off) #define ALLLED_OFF_H 0xFD //load all the LEDn_OFF registers, byte 1 (turn 8-15 channels off) #define PRE_SCALE 0xFE //prescaler for output frequency #define CLOCK_FREQ 8000 //8kHz default emax esc clock void setPWMFreq(int); void setPWM(uint8_t, int, int); void setPWM(uint8_t, int); int getPWM(uint8_t); void setAllPWM(int, int);
I don't now much in regards to arming the ESC or if the Frequencies are setup correctly, just randomly trying stuff at this point.
Any help would be great, fun stuff, love to get me motor spinning.

Re: cold reset of IPMI required after S2600WT maintenance?
The behavior described is not normal. (of course you knew that or you would not be making this post.)
When you added the x710 card, did you remove the AC from the system?
The system stand-by power is on any time AC is connected.
I am thinking something weird might have occurred if you hot plugged the card.
