1.6 4.20g security disclaimer

This product is designed and configured as a developer device. As such it includes only basic functionality and

requires you as the developer to add the capabilities necessary for your particular uses. The device does not

include any specific or enhanced security functionality and is configured by default to be openly accessible to aid

your development. Specifically the device does not include or support any limitations or controls on what software

can be executed or booted by the hardware. There is no secure boot, secure update, or other firmware control

mechanisms. This means that anyone with physical access to the device can change the software (firmware)

running on the device. By default the administrative access to the device, including the supplied Linux softwareimages, is also not access restricted. Anyone with physical access to the device can access administrative privileges

(i.e. root access) to inspect or modify the device without a password or other authentication. If your use requires

these interfaces be secured, you are responsible for adding or configuring capabilities to do so.

1.7 Features in this release

SoftwareServo library. Software emulation of the Servo library. PWM servo signals are bit-banged instead of using

the hardware PWM on the Intel Edison device. The SoftwareServo library can be used in any digital pin (0-13). Use

of SoftwareServo library is similar to that of the standard Servo libraryhttp://arduino.cc/en/reference/servo.

softAnalogWrite(). Software emulation for PWM functionality for Intel Edison. PWM signals are bit-banged instead

of being generated by dedicated hardware. Does not have the 8-bit limitation of the built PWM hardware of the

Tangier SoC used for Edison. You may use softAnalogWrite()in any of the digital pins. Use is similar to that of the

standard PWM, but instead of analogWrite(), use softAnalogWrite().

Serial2. Serial2 is now enabled for Intel Edison. This Serial2 is connected to the USB debug port (FTDI) on the

Arduino* board. Using Serial2 disables the console on the USB debug port until Serial2.end()is called.

Introduction

1.8 Known issues

Issue # Section Description

MAKER-200 1.8.1 Uploading Galileo sketches to Edison spawns zombie processes.

MAKER-210 1.8.2 Renbotics ServoShield2 does not work properly.MAKER-211 1.8.3 pinMode() and analogRead() triggers interrupts on an attached pin.

MAKER-200: Uploading Galileo sketches to Edison spawns zombie1.8.1

processes.

If you accidentally upload a Galileo sketch into Edison, the upload process will succeed because the process is

identical on both boards. However, when clloader attempts to start the binary file, it will fail and spawn a zombie

process.

Uploading a sketch from the wrong target should be prevented from being uploaded.

On Mac OS X this breaks upload capability after uploading a sketch built for the wrong target.

Windows is able to recover. The first upload (correct target) fails, but subsequent ones are successful.

MAKER-210: Renbotics ServoShield2 does not work properly.1.8.2

Edison only: Some shields that use I2C may not work because they have pullup resistors that are too strong.

Replacing these with weaker pullup resistors (10 kohm) or removing the resistors altogether should allow the

shields to work.

MAKER-211: pinMode() and analogRead() triggers interrupts on an1.8.3

attached pin.

Edison only: When an interrupt is attached using attachInterrupt(), callingpinMode()and analogRead()for the first

time triggers an interrupt. This is due to the muxing operations done when those functions are called. To avoid this

issue,pinMode()should be called before attachInterrupt(), and analogRead() should also be called at least once foreach pin used before calling attachInterrupt().

7/21/2019 Galileo 1.0.4

10/12

Resolved issues

2.1 Resolved in v1.0.3

MAKER-171: Remove workaround for gpio130 issue.2.1.1

We removed this workaround since the BSP already has the fix integrated. (This applies to prerelease Edison

firmware only.)

MAKER-183: Fix bug in pulseIn.2.1.2

Some outdated code in thepulseIn()implementation for Galileo, which only affected first generation boards,

limited the capability ofpulseIn()in detecting pulses that occur quickly afterpulseIn()is called. Removing these two

lines when things are being set up for first generation Galileo boards resolved the issue.

MAKER-184: Merge Edison and Galileo branches.2.1.3

Done.

MAKER-186: Remove temporary SPI workaround.2.1.4

After calling SPI.transfer()there is a long pulse before the actual clk. This causes external SPI devices to not work atall. It also takes more time to transfer one byte of data because this is present in every transmission of a byte. The

fix removes the issue of a long pulse in SCK that limits SPI to one transaction every 20 ms.

Note: You must update the Intel Edison firmware to the latest release available.

MAKER-187: Wi-Fi library fixes.2.1.5

We updated the Wi-Fi library to make it work on the Intel Edison board with wireless tools. Changes implemented:

Updated wpa_supplicantconfig file path to its new location in/etc/wpa_supplicant/wpa_supplicant.conf.

Removed hardcoded interface name.

Fixed issue that caused the sketch to get blocked when calling Udp.parsePacket(). The flush()function would

read and discard data on the socket without updating the internal remaining bytes counter. This issue isreproducible with WiFiUdpNtpClientsketch.

Fixed issue that prevented the UDP class to respond to the remote client with a UDP packet. The remoteIP

and remotePort were not being updated properly. This issue is reproducible with WifiUdpSendReceiveString

sketch.

MAKER-188: Build Windows release with 7-zip file extension.2.1.6

The final Windows version of the software now uses the 7-zip extension, rather than just .zip.

MAKER-189: Implement an easier interface for fastGpio.2.1.7

Previously the user had to know to use the GPIO_FAST_IOx. We have added new wrapper functions so that users

only have to specify the arduino pin ID.

MAKER-191: Create macros for Edison for fastDigitalRead and2.1.8

fastDigitalWrite.

Done.




7/21/2019 Galileo 1.0.4

11/12

Resolved issues

MAKER-193: Sketch upload for Edison not stable for Linux builds.2.1.9

Sketch Upload for Edison failed to upload after ten tries. A board reboot will fix the issue. With this releases

clloader improvements, sketches terminate and restart when the USB cable is unplugged.

MAKER-194: Prevent Wi-Fi library from deleting wpa_supplicant.conf.2.1.10

The IDE Wi-Fi library deletes /etc/wpa_supplicant/wpa_supplicant.conf. This is acceptable for a sketch, but it

breaks the wpa_supplicantoperation when used outside of a sketch. (This issue is also present in all Galileo

versions, as the code was inherited from there.) By removing the rmcall, and using wpa_cli to initialize the WPA

keys (instead of overwriting the config file with the output of the wpa_passphrasecommand), it is possible to

configure the WPA keys and maintain the wpa_supplicantoperation when the user goes back to the Linux use case.

MAKER-195: Remove Arduino IDE calls to ifup/ifdown in Wi-Fi library.2.1.11

We removed ifupand ifdownin BSP because we are using wpa_supplicantand wpa_clito manage the Wi-Fi. Having

ifup/ifdownwould add another (possibly conflicting) method, so it is safer to modify the Wi-Fi library to use wpa_cli.

MAKER-197: EFI debug output.2.1.12

Galileo shows EFI debug messages during boot time.

MAKER-198: Rename Firmware Update option.2.1.13

We renamed the Firmware Updateoption to Galileo Firmware Update.

MAKER-199: Prevent Galileo Gen 2 from downgrading to 1.0.2 or earlier.2.1.14

Galileo Gen 2 is supported by firmware 1.0.2 or later only.

MAKER-201: Compiled sketches are too big.2.1.15

We increased the sketch limit to 10,000,000 bytes.

MAKER-202: Fix HardwareSerial implementation.2.1.16

Fixed by declaring HardwareSerial to be virtual.

MAKER-203: Add a version number for IDE releases.2.1.17

We have added version numbers to the IDE, to reduce confusion over releases.

MAKER-209: Add Intel release number to IDE version.2.1.18

Done.

2.2

Resolved in v1.0.4

MAKER-30: Need better wireless support.2.2.1

SD Card image now includes the following Wi-Fi firmware support:

iwlwifi-6000g2b-6

iwlwifi-6000g2a-6

iwlwifi-135-6




7/21/2019 Galileo 1.0.4

12/12

Resolved issues

MAKER-95: RTC 79563 Loopback of USB client to host fails after few2.2.2

cable pulls/inserts.

This issue has been resolved.

MAKER-118: USB is unusable on 1.0.1rc5.2.2.3Improved USB stability on Galileo.

MAKER-177: pinMode breaks PWM on same pin on Edison.2.2.4

When analogWriteis called, it checks if the pin is currently set as PWM. If it is, then it does not turn it on again. This

also skips the muxing of the pin.pinModedoes its intended muxing operation for GPIO but keeps it marked as a

PWM pin (if it was previously marked as a PWM pin). As a result, ifpinModeis called after analogWrite, all the

analogWritecalls after thepinModecall will not do the muxing operations. This was the same situation on Galileo,

and the fix for Edison is the same.

MAKER-205: shiftout() must be supported.2.2.5

The software shiftout()function is now supported.

MAKER-213: Wi-Fi library does not work on some home wireless2.2.6

networks/routers.

The Wi-Fi library did not work for some wireless networks. We increased the delay, so it should work for most, if

not all, routers. If it doesnt resolve the issue for your router, increase the delay on the library to ensure that it

connects and gets an IP address successfully. Experiment until you find the optimal delay value so that your router

will work but the delay is not too long.

MAKER-214: Update tone library.2.2.7

We updated the tone library to work on first generation Intel Galileo boards, and replaced digitalWritewith

fastDigitalWriteto increase supported tone range and accuracy.

MAKER-215: Port Ethernet Shield library.2.2.8
