Firmware download procedure

Danger:

High voltage is present on the PSR-ZVS demonstration

board.

Caution:

Users must take care about relevant safety procedure before handling the board, even

before initiating a firmware upgrade.

The firmware upgrade procedure requires the STM8_pgm.exe program provided by

Raisonance. The user shall install the Raisonance RIDE 7 tool. Please refer to

www.raisonance.com.

The new firmware is normally provided into a zipped file containing:

•

Firmware (stlux385_PSR_ZVS_V3Rxx.hex file, where the final “xx” refers to the

release number)

•

Batch file (program.bat)

The batch file instruments the “STM8_pgm.exe” program to erase and program the new

firmware to the STLUX385A. The batch file also verifies that the download was successful.

The following steps shall be performed:

Modify the “program.bat” batch file to map the current STM8_pgm.exe location.

Use an isolated power supply and apply 14 V (+/- 0.5 V) via TP31 (+14 V) and TP25

(GND) without any other power voltage (especially on the AC power line). This

condition guarantees the safest firmware upload condition for both the user and the

board.

Use the “program.bat” procedure. The result of this action is shown in Figure 29:
