[CW6.0 MC9S08DZ60] Absolute section overwritten

Nouchi — Thu, 29 Oct 2020 08:45:52 GMT

Hello,

If do that in the prm file:

Code:

ROM =  READ_ONLY  0x1900 TO 0xFFAD FILL 0x8D; /* fill with an ILOP */

and that in my C file

Code:

const char SoftWareVer[3] @0xBE00 = {0,3,0};

SoftWare constant is overwritten by the FILL directive, is it normal?
I'm looking for a workaround.
any ideas?

Emmanuel

Hi Emmanuel,
the easiest thing would be to split up your ROM part in the .prm, something like this:

ROM1 =  READ_ONLY  0x1900 TO 0xBDFF FILL 0x8D; /* fill with an ILOP */
/* Gap for 0xBE00..0xBE02 where we writhe SoftWareVer[3] */
ROM2 =  READ_ONLY  0xBE03 TO 0xFFAD FILL 0x8D; /* fill with an ILOP */

You will need to update the PLACEMENT as well to reflect ROM1 and ROM2.
