Hi All,
I am working on a bootloader for STM32F429ZIT6. And for the project we are using Touch GFX and FreeRTOS.
The problem I have currently is:
- If I create a regular project without touchgfx code or free rtos code in it. I can properly jump from bootloader to user application.
- But If I create a project with either TouchGFX or FreeRTOS The jump is failing from bootloader. But I can run this project using debug normally.
I read a lot of posts online regarding this. And everyone have to say something with Interrupt but none of the solutions are working. Below is my code
BOOTLOADER.(where I am jumping to user application)
if(!bootLoaderVerifyCRC(rxBuf, packetLength - CRC_PACKET_LENGTH, hostCRC))
{
bootLoaderSendAck(1);
uint32_t goAdress = *((uint32_t *)&rxBuf[2]);
uint32_t* baseAdress = (uint32_t *)goAdress;
if(verifyAddress(goAdress) == ADDR_VALID)
{
bootLoaderUARTWriteData(&addrValid,sizeof(addrValid));
__disable_irq();
__set_MSP(*baseAdress);
uint32_t goToAddress = *(volatile uint32_t *)(baseAdress + 1);
void (*jumpToLocation) (void) = (void *)goToAddress;
jumpToLocation();
}

}
and in the system_stm32f4xx.c file I have added below line
#define VECT_TAB_OFFSET 0x20000
But individually this code works if I debug instead of jumping.
I am stuck here for a long time. Any help is highly appreciated.
Thanks,
krishna
