H7A3 - Code not loaded into ITCM-RAM Hi all,i have an issue with an STM32-H7A3, which is going into hard fault, when calling a function, which is moved to the ITCM-RAM.I have defined a section for ITCM-RAM in the Linker-Script: _siitcmram = LOADADDR(.itcmram); /* size of ITCM-RAM */
.itcmram : { /* ITCM-RAM Section */
. = ALIGN(4); /* Alignment: 4 Bytes - "Word" - u32 */
_sitcmram = .; /* define a global symbols at itcmram start */
*(.itcmram)
*(.itcmram*)
. = ALIGN(4);
_eitcmram = .; /* define a global symbols at itcmram end */
} >ITCMRAM AT> FLASH /* reseve memory in flash for this section */ I copy the code from the flash to the ITCM-RAM in the startup // BEGIN MODIFICATION - STM-CubeMX Code above
/* Copy from flash to ITCMRAM */
ldr r0, = _sitcmram // start: itcmram start
ldr r1, = _eitcmram // end: itcmram end
ldr r2, = _siitcmram // size
movs r3, #0
b LoopCopyCCMInit
CopyCCMInit:
ldr r4, [r2, r3]
str r4, [r0, r3]
adds r3, r3, #4
LoopCopyCCMInit:
