BSL Tool - Configuration
•
Target Device - select the target device from the pull-down list.
•
Protocol - select the desired BSL protocol and BSL interface:
-
Normal LIN - BSL communication uses real LIN frames, Master-Request frames, and Slave-Response
frames. In order to distinguish these BSL LIN frames from real LIN frames, the checksum is inverted.
Communication is via the target device integrated LIN transceiver.
-
Fast-LIN - UART like BSL communication using the device integrated LIN transceiver. This is the default
protocol for new, unprogrammed devices.
-
UART - full-duplex UART communication over UART1 of the target device.
•
Baud Rate - selects the communication baud rate.
•
Pin VS - selects the usage/behavior of the VS pin (Pin 6):
-
Off - the µIO-Stick integrated charge pump is switched off, VS must be supplied by the target system,
