Bugfix Fontpack update for large blocks:
The update of a font pack with a size > 768000 byte was interrupted and a manuel switch to bootloader had to be performed to get the font pack flashed. Rootcause was a missing address adjustment during the block read back function which caused a false error detection. Blocks > 768000 are read in two step while only one buffer is used for comparation. To fill the correct data into this buffer a dummy read of the flash data was added to get the data pointers to the correct offset. Another bug was regardings the read back itself where only the first byte was checked. After array indexing the complete buffer is noch verified.
