STM32F3Discovery not working

[indesigns]

Hi,

I have used the MikroC Pro for ARM somewhat, made a few programs that worked...also bought the registered version in dongle form.

Recently, MikroC updated, and now any program that I make does not run...the microprocessor seems to hang. I did a very basic new program to prove the tool chain...and it still does not do a thing. Code snippet below:

sbit Ld7 at GPIOE_ODR.B11;

void main() {
GPIO_Clk_Enable(&GPIOE_BASE);
GPIO_Digital_Output(&GPIOE_BASE, _GPIO_PINMASK_11|_GPIO_PINMASK_12);

while (1) {
Ld7=~Ld7;
Delay_ms(100);
}

}

I'm using Mikro C 6.2 with the STMicroElectronics ST-Link.

Below is the assembly code generated:
_main:
;MyProject.c,3 :: void main() {
;MyProject.c,4 :: GPIO_Clk_Enable(&GPIOE_BASE);
MOVW R0, #lo_addr(GPIOE_BASE+0)
MOVT R0, #hi_addr(GPIOE_BASE+0)
BL _GPIO_Clk_Enable+0
;MyProject.c,5 :: GPIO_Digital_Output(&GPIOE_BASE, _GPIO_PINMASK_11|_GPIO_PINMASK_12);
MOVW R1, #6144
MOVW R0, #lo_addr(GPIOE_BASE+0)
MOVT R0, #hi_addr(GPIOE_BASE+0)
BL _GPIO_Digital_Output+0
;MyProject.c,7 :: while (1) {
L_main0:
;MyProject.c,8 :: Ld7=~Ld7;
MOVW R2, #lo_addr(GPIOE_ODR+0)
MOVT R2, #hi_addr(GPIOE_ODR+0)
LDR R1, [R2, #0]
UBFX R0, R1, #11, #1
EOR R1, R0, #1
LDR R0, [R2, #0]
BFI R0, R1, #11, #1
STR R0, [R2, #0]
;MyProject.c,9 :: Delay_ms(100);
MOVW R7, #4521
MOVT R7, #4

L_main2:
SUBS R7, R7, #1

;MyProject.c,10 :: }
IT AL
BAL L_main0
;MyProject.c,12 :: }
L_end_main:
L__main_end_loop:
B L__main_end_loop
; end of _main


Please advise...if it would be helpful, I could zip the entire project and provide link.

Thanks

Hi Rick,

Welcome to the mikroE forum.

How did you set configuration bits in the Edit Project?

Would you like to attach your project (zipped), or send it directly to my email [stefan.filipovic@mikroe.com]?

Kind regards,

Hi Stefan,

Please find attached.

Using the internal RC oscillator for the clock.

Thanks for you help as well.

Hi Rick,

There is a mistake in the STM32F303VC.mlk file.
Please press Ctrl+Alt+M to open up mlk file, and modify the node for RAM memory range as shown below:

Code: Select all

<RAM>
		<MIN_ADDR>0x20000000</MIN_ADDR>
		<MAX_ADDR>0x20009FFF</MAX_ADDR>
</RAM>

Please let me know does it works after that. Don't forget to Rebuild All Sources (Alt+F9) after modifying.

I will forward this to our developers, I apologize for the inconvenience caused by this.

Kind regards,

Right on Stefan...worked like a charm.

Thanks very much for your help.

Best regards,
