Bootloader, Application, Structures and deep pointer

Bootloader: C:0x0000 - C:0x7FFF
Manages CAN-Communication and in-field update.
Application C:0x8000 - C:0xEFFF
Applications is controlled with bootloader over CAN 2.0.

Compiled both seperatly and merge the Hex-file. Interrupts and function calls work.

At level of 8 successive funtions calls the acces to an struct in Applications XDATA mem is incorrect. The expected pointer is not given.

Any adwise?

  • I am very happy with the way it does things, that it is intended for, it does such things beautifully

    No one would expect a racehorse to do the work of a mule, or vice versa.

    The post I comment on illustrates how blatantly ignorant some are matching the application and the processor.

    Whoaaa ... wait a minute. Easy on the coffee, maybe try decaf ?

    I'm not the one who's trying to do floating point math in an ISR, or implement paged virtual memory on a '51, or juggling function pointers around. My '51 project works just fine, and the MCU is quite suited for the task I have.

    If you want "C is C" stay with your beloved PC.

    I haven't programmed on a PC in, uh, years, and nothing I ever did on a PC was even close to a commercial project. I started directly with DSPs and uCs, and my very first project was pretty much pure assembly, except for some boring clerical parts that were easier to do in C.
