I am trying to get a MRF24j40 on a BeagleBone Black to talk to an arduino with a mrf24j40. I have successfully communicated arduino to arduino but as of yet have not been able to receive the packets being sent out on the BBB.
The setup: I have GPIO_13 going to reset (pin 2), GPIO_14 going to wake (pin 3) and GPIO_29 going to interrupt (4). The 3.3v is going to vin on 10 and ground on pin 1. I am using SPI1 with the HDMI ports disabled. D0 is mapping to pin 7 (SDO) and D1 is mapping to pin 5 (SDI), P9.31 the clock goes to pin 6 and P9.28 goes to pin 8.
I have been able to log into the BBB via ssh. I then load the cape for the MRF24j40 using the echo to /sys/devices/bone_capemgr.9/slots
This appears to load the driver properly.
I have then been able to do:
iz listphy
iz: /lib/arm-linux-gnueabihf/libnl-genl-3.so.200: no version information available (required by iz)
iz: /lib/arm-linux-gnueabihf/libnl-3.so.200: no version information available (required by iz)

Registered new device ('wpan0') on phy wpan-phy0
I decided to set all my addresses to simple things on the arduino side in case there is some sort of endian problem so the pan id is 0, the address of the sender is 0 and it sends the data to 1, thus I try to set the beaglebone to pan id 0, address 1 with a destination address of 0.

ifconfig wpan0 up
Then I run
izchat 0 1 0
I get nothing on the BBB side even though the other side is constantly transmitting... and when I type into izchat, I do not receive anything on the other side.
Any help here would be appreciated... I just want to see some data before I start coding. Like I said, this has been tested arduino to arduino and does not have problems.

I have a custom nrf52 chip on a pcb with swd pins exposed. I have cloned and installed the latest openocd from https://github.com/ntfreak/openocd. The latest version includes all the latest pathes for the nrf52 chip, so no need for any additional changes as suggested in many older guides online. I am able to connect to the chip using ST-LinkV2. when connected I can read and write memory locations using mdw and mdb. I can also run some basic openocd commands like dump_image e.t.c, which confirms that the setup is good. But halt and program commannds always lead to errors like:
JTAG failure -4
JTAG failure -4

jtag status contains invalid mode value - communication failure
Polling target nrf52.cpu failed, trying to reexamine
I have read different guides online, and one of the possible solutions involves the APPPROTECT register which has to be disabled to enable any writes to flash.
APP_PROTECT, But the dap commmand which is supposed to help us access this bit,
dap apreg 1 0x04 0x01
returns an error:
invalid subcommand apreg 1 0x04 0x01
Please, I will like to know if anyone has had success programming a new empty nrf52 chip with the stlink-v2 and the steps which are necessary, or if any one has encountered similar problems. Thanks.
Here is my config file:
#nRF52832 Target
source [find interface/stlink.cfg]
transport select hla_swd
source [find target/nrf52.cfg]
#reset_config srst_nogate connect_assert_srst
I solved the "protected nRF52" chip problem this way, on Windows, using a Particle.io Debugger https://store.particle.io/products/particle-debugger setup to program nRF52 chips from Arduino as described in https://www.forward.com.au/pfod/BLE/LowPower/index.html
Note: The recovery process described here does NOT need Arduino to be installed
Download OpenOCD-20181130.7z pre-compiled openocd for windows from
http://gnutoolchains.com/arm-eabi/openocd/
The latest version of openocd src on https://github.com/ntfreak/openocd should also work as it includes the apreg cmd in target\arm_adi_v5.c
unzip, open cmd prompt to unzip dir, enter cmd

Can now use arduino ide to flash softdevice and code low power BLE
Even though the dap command is listed by openOCD help, it isn't implemented for transport hla_swd that you have to use with ST-Link.
If the ST-Link is a generic type from China, it can be upgraded to CMSIS-DAP which uses the swd transport and supports the nrf52.dap apreg 1 0x04 0x01 command to disable the readback protection and erase the flash. You'll need another ST-Link to do that, or you can instead install CMSIS-DAP on a generic STM32F103C8T6 board.
After that you can either use ST-Link to program the nRF52 or continue using CMSIS-DAP, which can also be used to program STM32 MCU.
Nucleo board embedded ST-Links can also be upgraded to J-Link, which allow the use of the "recover" option in nRFgo Studio to erase the flash, it should also work with "nrfjtool --recover" or OpenOCD.
If anyone encounters this problem, I solved the problem by getting an original Jlink-Edu. I also had to pull the reset pin of the microcontroller high to get the jlink working.
There are lots of JTAG messages.
I think you might be missing the
transport select hla_swd
line in your (board) cfg file. The NRF5x chips only work properly with SWD, and ST-Link uses the hla_swd variant.
I want to connect an 5" HDMI display (26 header pins) to a Raspberry Pi 3. I also want to use UART0 (Tx=GPIO14, Rx=GPIO15).
So I remapped UART 0 to Tx=GPIO36 and RX=GPIO37 by using the command in config.txt file:
dtoverlay=uart0 ,txd0_pin36,rxdo_pin=37,pin_func=7 # alt 3
I also included the following commands in rc.local:
raspi-gpio set 14 ip
raspi-gpio set 15 ip
On entering raspi-gpio get command, I am getting TXD0 and RXD0 enabled at GPIO14, GPIO15 and GPIO36, GPIO37 respectively, but still serial communication is not working. Though it was working on GPIO14, GPIO15.
Now how to enable serial communication on GPIO36, GPIO37?
I have an LG B470 flip phone. I want to be able to send and receive text messages from my Mac Laptop running OS X 10.10.5.
I have the phone plugged in via USB. I can send SMS messages using the minicom terminal. However, attempting to list or read SMS messages from the phone/modem causes the modem to stop responding:
AT
OK

Manufacturer: LG ELECTRONICS
Model: LGB470

OK
AT+CMGS="+12146168895"
> Hello World.
+CMGS: 169
OK
AT+CMGL="ALL"
I get no response and can no longer communicate at all. Typing is not echoed back and if I turn local echoing on and attempt to send the AT command I get no response. The only way to get the modem to respond is by restarting the phone (unplugging and plugging back in the phone's USB, etc. does not help).
The same thing happens after AT+CMGR commands.
Question
Why does the phone/modem stop responding after AT+CMGL and AT+CMGR commands? How can I fix this so I can get incoming SMS messages from my phone to my mac? Any tips on how to debug?
Setup
I did not install any drivers. When I plugged my phone into my mac via USB it was recognized automatically. It is shown as an internet modem in System Preferences->Network. Some character devices were also created:

tty.lgusbmodem1411 (lg usb modem 1411) and tty.lgusbserial1411 (lg usb serial 1411) disappear and reappear when I unplug and plug in the phone's USB. tty.LGB470-LGPCSuite is always there and seems to reference the LG PC Suite software which is not compatible with my phone.
I can also connect to it via Bluetooth and transfer files via the "Bluetooth File Exchange" app.

Additional Info
As reported by the ATI command, my LGB470 phone uses the Qualcomm QSC6270 "HEDGE (HSDPA/WCDMA and GSM/GPRS/EDGE)" chipset. I can not find documentation on the GSM modem/AT commands, however.
I have 4 NodeMCU boards, 3 of them I can use and 1 I can't seem to upload any of my code to. It does boot, and I can get a readout of it on the serial port.

I also tried doing a reset with the flash button held down:

I don't get any compile errors with my code, and the code works perfectly fine on the other 3 NodeMCU boards. When I try to upload (regardless of boot mode) I see the blue light near the ESP8266 chip blink a couple of times, and then I get the following errors output:

I've also tried grounding D0 and connecting the EN pin to 3.3v, which changes the boot mode to ets Jan 8 2013,rst cause:2, boot mode:(1,7) and the red onboard LED turns on, but still doesn't allow me to upload code.

I have a Pololu PGM03A isp dongle to programm microcontrollers via avrdude. It worked great under Yosemite, but under El Capitan, it seems to disconnect and reconnect randomly every 1 - 5 sec. I can see this by the green status LED and in the terminal:
Macintosh:~ xxxxx$ ls /dev/cu.*
/dev/cu.Bluetooth-Incoming-Port /dev/cu.usbmodem00070153
/dev/cu.serial1 /dev/cu.usbmodem2169
/dev/cu.usbmodem00070151
Macintosh:~ xxxxx$ ls /dev/cu.*
/dev/cu.Bluetooth-Incoming-Port /dev/cu.usbmodem00070153
/dev/cu.serial1
Macintosh:~ xxxxx$ ls /dev/cu.*
/dev/cu.Bluetooth-Incoming-Port /dev/cu.usbmodem00070153
/dev/cu.serial1 /dev/cu.usbmodem2177
/dev/cu.usbmodem00070151
As you can see, the usbmodem00070151 is there, then not, and then again available. The usbmodem00070153 belongs to the ISP Dongle too, but it provides an different feature than programming the microcontroller (it's an USART Port or something I think).
Edit: The latter modem now also disconnects.
When I try to flash the microcontroller, it sometimes manages it to write some bytes, but the time between 2 disconnects is to short to finish the job:
Writing | ######################## | 47% 0.08s
avrdude: ser_recv(): read error: Device not configured
make: *** [all] Error 1
Does anyone know how to fix this?
