68HC11_romloader

HC11 Romloader is a small program that is bootstrapped into an 68HC11F1 and does program the internal program memory (FLASH). The ROM content (payload) of 512 bytes is attached as hex dump. This hex dump can be generated from the binary ROM image (output you your assembler) using the romconv tool included.

Get started:

• Compile/assemble your HC11 code that shall be written into the internal FLASH ROM
• Take the resulting binary output file (ROM image 'dump.bin') and feed it into the 'romconv' utility. This will create a file 'dump.hex'
• Copy/Paste the content of 'dump.hex' into 'romload.asc'
• Assemble romload.asc
• Load romload.asc in bootstrap mode (via serial port). The HC11 internal Flash and EEPROM will be erased.
