MCLoader & XPort

Try the original HIJACKING way since I couldn't get it to work with our own DEFINE the second time I tried it.

If you are using MPLAB you can look under view and program memory to see what your code looks like.

Try the original approach:

1: Change the LOADER_USED line in the LIB
2: DEFINE LOADER_USED 1 in your code
3: Compile
4: Check program memory, there should be code in position 0 and 2 then FFFF until $EB00

Syntax in PBP can be a little bit tricky. Some functions don't really like that you have a formula as argument. They want to have a WORD or BYTE only.

DEFINE LOADER_USED 1
DEFINE HSER_RXSTA 90h
define HSER_TXSTA 24h
DEFINE HSER_BAUD 9600

This is with the DEFINE LOADER_USED in the lib file like this

ifdef LOADER_USED
LIST
ORG 60160 ; Own loader address
NOLIST
endif

Any luck now??

Jumper,

It seems like that's better. Here is dump result:
:4
:0
:9E
:AA
:FD
7
:AE
:50
8
:80
:E1
:EF
:75
:F0
:E9
:50

But we should be able to do this with a custom DEFINE, no??

I didn't really look into this because I never use any other loaders but maybe this forum can come up with an answer.

This will not be solved today since we have passed Midnight a long time ago here.

Maybe moving this to a new thread might be a good idea after we have solved these problems. Then all our misstakes will be forgotten......

Jumper,

Looking at the .lst listing. the code appears to start at $EB00, even though the ORG directive specifies 60160

EB00 is 60160

Remeber some numbers are in Decimal and some in HEX

I might be doing the math wrong, but by my calculation EB00 is

E(15) * 4096 + B(11) * 256 + 0 + 0 = 64256
