Custom Project for H750-DK board from cubeide and touchgfx get stuck in __ExtMem_Boot_bin_Start()

[Kasun Dinesh]

HI,

I am trying to create a touchgfx application project from cube ide for H750 board. I was able to get everything compiled after merging lot of things from the project created from touchgfx it self for h750 board. But once i run my custom project, it gets stuck inside _binary____ExtMem_Boot_bootloader_bin_start() at 0x8001ca0.

This is my call stack

Please help me out. Thanks

Sure you're not missing an interrupt handler?

Step around, what's it actually stuck up on?

[Kasun Dinesh]

It is stuck on this bootloader binary. Can't debug or go step by step. It requires the bootloader because h750 code is running in external memory.​

I have changed the interrupt vector as well as in the example provided by touchgfx.

#define VECTOR_TABLE_LOCATION Image$$ER_QSPI_FLASH$$Base

Problem got solved after adding

#elif defined(VECT_TAB_QSPI)

 SCB->VTOR = (unsigned int)&VECTOR_TABLE_LOCATION; /* Vector Table Relocation in External FLASH */

to the section below in systemInit function

 /* Configure the Vector Table location add offset address for cortex-M7 ------------------*/

#ifdef VECT_TAB_SRAM

 SCB->VTOR = D1_AXISRAM_BASE | VECT_TAB_OFFSET; /* Vector Table Relocation in Internal D1 AXI-RAM */

#elif defined(VECT_TAB_QSPI)

 SCB->VTOR = (unsigned int)&VECTOR_TABLE_LOCATION; /* Vector Table Relocation in External FLASH */

#else

 SCB->VTOR = FLASH_BANK1_BASE | VECT_TAB_OFFSET; /* Vector Table Relocation in Internal FLASH */

#endif

#endif /*DUAL_CORE && CORE_CM4*/
