Developer’s Serial Bootloader, Rev. 13
Freescale Semiconductor 63
10.1 Bootloading operation (command line version)
Open a command prompt in the Linux or Windows directory where the copy of hc08sprg executable
and S19 files are.
Assuming the serial board is connected to, for example, a second serial port (COM3 /dev/ttyS1, with speed
sets to 115200 bd/s and short trim is used) and is not yet powered on, invoke the bootloader using following
sequence: hc08sprg.exe 3:D* 115200 k60_test.s19
Figure 38. Bootloader invocation
The bootloader now expects the ACK command to be received from the MCU bootloader-enabled
application. Then turn the power on for serial board and if all connections are OK, the MCU begins
communication with the PC. The calibration procedure does not occur if the bootloader version with
known communication speed is used followed by IDENT command. The information that is acquired from
the MCU is then displayed on the screen (Figure 39).
