Just want to know how to set the priority of interrupts with STM32 MCU with mikroC PRO.

Thanks a lot,

Henry

Hi,

In order to jump to the new location for the application program by the bootloader code, I also tried to set the reset entry value (address of 0x00000004) to 0x3000 with

FLASH_Write_Word(0x00000004, 0x3000);

The value did not change. Any clue on that?

Thanka a lot,

Henry

Hi Darko,

It is STM32F103

Henry

Trying to build a bootloader with MiKroC Pro for ARM and need to use assembly in C to jump to the application program. Tried these assembly instructions:

asm MOVR1 #0x3000;

or

asm MOV R1 #0x3000;

The C complier said the assembly instruction MOVR1 or MOV was not found.

Any clue on that?

Henry

Hi there,

Do we have the same goto assembly instruction in MiKroC Pro for ARM?

Thanks a lot,

Henry

Hi there, Could you direct me to the creator of the USB HID bootloader example? It is a very good example and I need to ask a couple of questions: 1. how do we build the application program, complie it from 0x00000000 and then flash them to the desired memory location along with the vector table? Or...

Hello, Despite the statement, that it is not possible, I have managed to write a bootloader in mikropascal, to write an application with relocated interrupt vectors and to update the application via CAN. And to jump from the bootloader to the application and vice versa. If you like to know details,...

Hi there, Wrote some codes to test whether we can change the vector table for my future OTA (over-the-air software update) application: void app (void) org 0x3000 { FLASH_Write_Word(0x8009010, 0x12345678); // write buffer with 32 long words } void main(void) org 0x5000 { NVIC_VTOR = (0x4000 << 8); /...

Hi,

Using this? -

NVIC_VTOR = 0x2000;

Thanks for any reply,

Hery

Hi Filip,

Thanks for the advice.

And what command we can use to relocate the vector table in MiKroC?

Henry

Tried to build a OTA bootloader for in application programming of STM32F103. The bootloader code starts at 0x00000000. The application code starts at 0x00003000. It is thus needed to set the reset entry value (address of 0x00000004) to 0x3000. Tried two methods: FLASH_Write_Word() or NVIC_VTOR = 0x3...

Hi there, Try to use the flash library for STM32F103 as: unsigned long status; unsigned long status2; unsigned long data_; status = FLASH_ErasePage(0x08008000); status2 = FLASH_Write_Word(0x08008000, 0xAAAAAAAA); prepareForFlash() ; The compiler eliminates both 'status' and 'status2' saying that the...

I got the same problem - PC out of scope error in debug mode.

Can anyone provide any insight?

Thanks a lot,

Hi Marina,

TIM2_DIER.UIE = 1

does set the UIE bit to 1 as I spent more time on debugging it and realized that it was cleared by another command.

Hi Marina, The compiler was re-installed and the problem goes away. It may be related to the compiler in some ways. Now, I am trying to work on Timer 2 and have some problems: 1. The compiler cannot recognize TIM2_CR1.DIR valuable as it cannot take this command: TIM2_CR1.DIR=0; 2. I tried to use thi...
