Instruction¶

This instruction explains how to update your firmware.

1. Entering to the ISP mode While shorting following pads, plug the USB connector. You can use a jumper wire.

When the mbed is plugged in this way, it will appear as a disk called "CRP DISABLED". When you see the drive, you can release the wire.

2. Trash the old firmware
Open the "CRP DISABLED" drive, so you can find a file called "firmware.bin". Please trash this old firmware.

3. Copy the new one
Please Drug&Drop the downloaded latest firmware into the "CRP DISABLED" drive. After that, do eject operation like usual USB flash drive.


4. Power cycling
Unplug the USB cable and wait about 5 seconds. After that, please plug it again. At this time, you don't need to press the "ISP" button.
"MBED" drive will be shown. You can use mbed HRM1017 as usual.


On OS X, you can not process this with finder. You need to do with terminal like below.

rm /volumes/CRP\ DISABLD/firmware.bin
cp /Users/$USER/Downloads/lpc11u35_sscity_if_crc.bin /volumes/CRP\ DISABLD/
sudo umount /volumes/CRP\ DISABLD/
