Function
Description
Initialize
Checks if the flash loader, which was dumped to RAM, is
available, initialized at the correct baudrate and ready to
operate. This function checks for a prompt character (“>”). If this
operation fails (e.g. no flash loader present), none of the
following functions will be enabled.
Blank Check
Reads out every byte of each flash-sector to check for non-
blank cells. The result is displayed in the flash-diagram on the
right side (red = not blank sectors; green=blank sectors).
Chip Erase
Erases the entire flash-ROM (all sectors).
Sector Erase
Erases one sector indicated by the sector number.
Call
This function will divert operation of the device to the specified
location. This terminates the flash loader.
Read
Reads out a given number of bytes beginning at the specified
address and displays the results in hexadecimal format on the
log-window.
Prog 32bit
Programs one word to flash at the specified address.
Read to File
Reads out the Flash content and writes to the given bin-file.
Prog File
Handles the transfer of the specified MHX-file to the flash
loader.
