WiLoader Revision G
The MCU’s type is selectable from the list of MCUs. Also using the “Read Sig” button, the
software reads MCU’s signature via WiLoader and automatically selects the correct MCU.!
The Erase button clears the memory when the flash memory is selected, and if EEPROM
memory is selected, it will write 0xFF all through this memory.!
When the Preserve EEPROM option is selected, the contents of the EEPROM will be buffered
during the Chip Erase operation and afterwards will be written again.!
The Table button opens the website page with the address http://www.engbedded.com/
fusecalc to help the user select the fuse bytes and the user can get the desired value of fuse
bytes by selecting the MCU and choosing the needed options.!
Note: The verify operation is page wise and will work like a write flash operation. Thus, if the
hex file selected does not contain all the contents of a page from flash, the remaining bytes
should be 0xFF for the verify operation to completed successfully.!
Note: The .eep file is exactly in the same format as intel hex files and is therefore treated by the
software as a hex file.!
Note: In the read operation, the memory content will eventually be written by the software on
the user-selected file. If the file or path itself does not exist, the software will create both the
path and the file itself. If the address is given relatively, it should be relative to the location of
the executable file WiLoaderFX. For example, if the user only writes sample.hex in the address
field, through out the read operation, a file with this name and the intel hex format will be
created along with the WiLoaderFX file in the bin folder. When using the Arduino patch, the bin
folder is located on the hardware / tools / avr / bin path and the WiLoaderFX file has been
copied by the patch software in that location.!
