OPERATION
68EVB912B32UM/D 3-28
Before using the FLOAD command, a target device must have been selected using the DEVICE
command that reflects the locations of the on-chip Flash EEPROM, on-chip RAM, and the I/O
registers when the part is reset. Failure to follow this restriction will cause the FLOAD
command to fail and may require that the EVB be reset.
Flash EEPROM programming voltage (Vpp) must be applied to the target MCU. If the target
system is another M68EVB912B32 board, Vpp may be supplied via header W8, with header W7
set accordingly. For more information on these EVB headers, see Table 4-1.
Because the FLOAD command downloads a small "driver" program into the target MCU’s on-
chip RAM, D-Bug12’s breakpoint table is cleared before beginning execution of the "driver".
This is necessary to prevent previously set breakpoints from accidentally halting the execution of
the driver program.
example:
S>FLOAD
Flash Programming Voltage Not Present
S>FLOAD
