MC56F82748 bin file modification.

MC56F82748 I need add some header information to bin file for bootloader, is there any suggestion about how to modify the bin file?

Hi, Terry,

I do not think you can change or add something in the *.bin, because the *.bin is binary file, it is binary code directly.

If you use S-Record file, you can add header part with S0 as prefix.

Hope it can help you

Hi xiangjun,

According to our customer's requirement, i should offer bin files for updating which should contain some header information, so updating can be judged whether should be conduct.

as your opinion, is this unreachable?

Hi,

I do not think it is okay to modify the *.bin file directly. As a workaround, you can change your application code, for example in your application code, in a specific address, you can write header, mark, version of application code so that the bootloader can read the version from the specific address.

Hope it can help you

Hi,

I attach the MC56F83XXBLUM.PDF, pls refer to the section 1.1.7.1 User’s Application Bootloader Configuration, which writes the BOOT_START_DELAY and BOOT_VERSION_PROMPT constants to a specified location by application code. Pls refer to the section.

Hope it can help you
