Hardware Requirements

A free USB port is required to update HardWaves devices.

Surfer

No additional hardware is required to update Surfer, since it directly connects to USB host port.

One - HW1

A USB-to-LVTTL UART cable is required.

A FTDI cable like TTL-232RG-VSW3V3-WE can be used, but requires a patch.

Using a sharp cutter, a part of plastic case has been removed, and brown wire has been moved on the pad shown in the image, between orange and green wires.

Any case, UART used signals are: RXD, TXD, RTS, DTR, GND and Power.

WARNING!!! A voltage of +3.3 [VDC] is required.

The image above shows HW1 Programming port. Odd pins ( #1, #3, #5) are in the bottom row, while even pins (#2, #4, #6) are in the top row.

Signals direction is indicated from the point of view of HW1 board.

1 GND Power GND Power & Signal Reference
2 /RST IN DTR MSP RESET Signal
3 BSL_TX OUT RXD TX Data (ONE -> Host/PC)
4 TEST IN RTS MSP TEST Signal
5 BSL_RX IN TXD TX Data (One <- Host/PC)
6 VDD Power +3V3 +3.3 [VDC] Power Supply

Software

Since TI BSL may erase EEPROM Segment A, programming with standard utilities will brick One.

A dedicated software utility will be available for download together the first software update.
