Command 93
H
– FastLIN: Set Session Baudrate
Firmware supports changing the FastLIN baudrate for the current FastLIN BSL session via command 93
H
.
The header block message contains the new FastLIN baud rate selection for the current FastLIN session. The
given parameter is not stored inside the NVM CS, and the FastLIN default baud rate takes effect when the
response has been sent back to the host.
This command is rejected if the BSL communication currently uses a different interface than FastLIN. The
command is also rejected if NVM HW read protection is applied to any NVM region.
The host waiting time before response is sent back/can be asked for:
• 8 ms
NOTE:
When sending this command, the response to the command will use the old baudrate. The new baudrate will
be set only after the response has been transmitted.
Returned error codes
The message can return the following error codes:
- ERR_LOG_SUCCESS
- ERR_LOG_CODE_NVM_IS_READ_PROTECTED
- ERR_LOG_CODE_FASTLIN_BAUDRATE_SET_FAIL
