Re: build Chibios Under Atollic  Topic is solved

Using F7 linker scripts it will compile (at least).

So, I was comparing the linker scripts for H7 and F7 and I see that flash0 anf flash1 although point to the same thing (?) they have different addresses, but not for H7 (bank1+bank2 vs bank1).

Code: Select all

    H7
    flash0  : org = 0x08000000, len = 2M        /* Flash bank1+bank2 */
    flash1  : org = 0x08000000, len = 1M        /* Flash bank 1 */
    flash2  : org = 0x08100000, len = 1M        /* Flash bank 2 */
    flash3  : org = 0x00000000, len = 0
    vs F7
    flash0  : org = 0x08000000, len = 2M        /* Flash as AXIM (writable) */
    flash1  : org = 0x00200000, len = 2M        /* Flash as ITCM */

The issue seems to be here:

Code: Select all

/* Flash region to be used for exception vectors.*/
REGION_ALIAS("VECTORS_FLASH", flash1);
REGION_ALIAS("VECTORS_FLASH_LMA", flash0);

If I change flash1 to flash0 the problem is fixed (aka linker error), if I put flash1 len = 0, the linker will complain that the .vector section won't fit.

Moving this in bug reports, I think it is related to another bug already reported.

TWIMC: As a workaround, replacing flash1 with flash0 on each alias compiles and works ok (on ST-Nucleo-H743ZI)

Code: Select all
