Hi,
we are developing custom bootloader, we are facing some issues when we configured SDRAM its not jumping to the specified address.
Working:
let us consider:
application two start address: 0x3022a000
Application one start address: 0x30025000
Binary file created with below memory configuration , and this file is writing respective Application one,
and its jumping to APP1 address it executing successfully.
Not working:
when We Configured SDRAM for storing string and sending through UART1 its not working.
When i configured SDRAM application not jumping to the specified location. its getting halt
code:
void JumpApplicationOne(void)
{
/*! @brief Jump to application function pointer datatype. */
typedef void (*F_Bootloader_Jump_t)(void);
PRINTF("jump_application1\n\r");
//NOTE: Don't modify the below code and no Debug printf
// Disable both D and I caches, Application will enable them back.
SCB_DisableDCache();
SCB_DisableICache();
// Data memory barrier.
__DMB();
DisableGlobalIRQ();
// Relocate vector table.
SCB->VTOR = (__IOM uint32_t)APP1_BASE_ADDRESS;
// Define Application function.
uint32_t jumpAddress = *(uint32_t*)(APP1_BASE_ADDRESS + 4U );
F_Bootloader_Jump_t jump = (F_Bootloader_Jump_t)jumpAddress;
// Set stack pointers to the Application stack pointer.
__set_MSP(*(uint32_t*)APP1_BASE_ADDRESS);
__set_PSP(*(uint32_t*)APP1_BASE_ADDRESS);
// Jump to Application.
jump();
}
How to resolve this issue.
if any further information required let me know.
