elftosb command file

[rans]

Hello,

I try to understand elftosb command file.

Is there a documentation which defines how to sef the values in the command file ? I did not find these in the elftosb user guide.

For example: how to set startAddress , initialLoadSize , entryPointArdress?

options {
flags = 0x00;
startAddress = 0x8000;
ivtOffset = 0x400;
initialLoadSize = 0x2000;
entryPointArdress=0x0000A000;
}

Another question related to mfgtool/elftosb:

Is it that elftosb adds IVT header (not only FCB) ?

Thank you,

ranran

You can also try this tool, with this tool, You can flash bare image into various boot devices easily and don't need to care about headers (ivt, boot data...)

Hi ranran

for bd file documentation one can refer to attached MCU Manufacturing User's Guide.
IVT structure is fixed and predefined. The needed information needs to be provided in
the .bd file while running elftosb command. If related information isn't provided, the tool
will use default value for it.

Best regards
igor
