Hi,

I need to program a EEPROM (I2C link) with a LPC1769 microcontroller. EEPROM data is 32 kBytes long and I can't store it direclty in the RAM (not enough ressources). I find the solution to store it in a const variable table (directly store in Flash) 32Kbytes long (example toto[32768]= {0x00,0x01,0x02 ..}; .The problem is if data change, I need to fill again the table with new value (values are from a .hex file).

I want to know if it is possible to ask the linker file to load the .hex file directly in Flash(maybe changing the file format if necessary). In this case, I don't have to fill the table. I just need to recompile the source code to update data.

Regards,
