I am using v4.3.5 of hex55 to generate a boot image for a SPI flash.
Command line = hex55 -boot -v5505 -serial8 myApp.out -o myApp.bin
The problem is that myApp.bin does not have the 0x09AA signature as the first word. I saw a previous post that said he needed to update hex55 utility. Wherer can I find an update?
