Tool for editing EEPROM single hex byte
I need to modify a byte of the Hex data block coming from an EEPROM and write it back to the EEPROM. Now the problem is if I simply do that, the CRC changes. Is there any tool in Linux for manually editing intel .hex files safely?

Flash and run a .hex file on a different Microcontroller with bigger flash from the same Cortex family
Is it possible to flash and run a compiled code (.hex-file) for a specific Microcontroller (for example STM32F205RC) on a Microcontroller from the same family with bigger flash-memory and RAM (without creating a new compiled version.)?
Example:

Why are data records in intel hex files often limited to 16 bytes, even for long contiguous blocks?
I'm not sure if this is true in general, but all intel hex files I have seen (from Atmel Studio, STM32CubeIDE and MPLAB) use data records with a length of 16 bytes. Even when the addresses written to are completely sequential there are just a lot of…
